Fatigue. I don't know the age of your 1845, but my VDP, with accessory pumps, are attached to a plate that is then attached to the engine. All this weight is carried by just two 1/2" bolts connecting the VDP to the plate. Given the vibration of the diesel engine, that's way too much stress for...

Do you bait it? I notice they say you don't have to use bait. I have two miniature dachshunds who have their nose in everything. The sticky traps work pretty good but I don't use them in the garage due to the dogs. This trap looks safer and more humane.

Me neither. There's a nearly vertical drop from the side of the engine cover to the muffler opening. When I began working on the engine this morning, I removed the paper towel shown in the previous picture and shone a light down the hole where the fuel injector goes, to see if I could catch a...

You might consider asking Terry about this behavior. I had this happen on my 1845 and the pump needed a rebuild. I'm not trying to scare you and your pump is different than the one used on the 1845. But this doesn't sound normal for a variable displacement pump. The only time I experience a...

I shared this on the Kubota Forum, but I thought it would be beneficial to repost the picture here. This is from my Kubota ZD1211 mower. The engine would not turn over and I couldn't figure out why, since it ran perfectly when parked for the season. For a while now, I've been concerned about...

I think I may have identified the problem. Next, I need to determine if there was any damage. Given that seeds can compress somewhat, I'm hopeful for a positive outcome. My plan is to use a depth micrometer to measure the clearance between the pistons and the cylinder head deck. If the...

Thanks of the comments. I thought I'd share a picture for those who might be curious. I've covered the injector and glow plug holes with a paper towel to keep them protected. I suppose the logical step is to start from the top, so I plan to remove the valve cover first. Then, I'll see what's...

Update. I removed the glow plugs and injectors, then attempted to manually rotate the flywheel. It moved to a certain point and then stopped. Next, I reversed the direction, moving the flywheel backward until it reached a stopping point. Following that, I used a Power Probe to actuate the...

I have a Kubota D1105 engine in a ZD1211 mower. When I tried to start it for the first time this year, the starter made a clicking sound. I knew the battery was going bad as it was getting slow to start last year, so I replaced the battery. However, when I turned the key over, the engine still...

Regarding motor oil, Kohler oil has more anti-wear additives, such as Zinc. Many of these additives were removed from conventional motor oil for emissions related reasons. In theory, it should be a fantastic oil for engines with no catalytic convertor. Shell Rotella Diesel oil is very similar.

Regarding other alternatives, take a look at Avant Tecno. They're WAY more expensive than a PT but do have diesel engines in their smaller versions. And, I'd bet they are more sophisticated than a PT wrt design, hydraulic filtration, lift capacity, etc... They can be found used on equipment...

As to the wheel motor seal, I remember reading a White motor is supposed to run at no more than 50% capacity for the first few hours. I don't remember how many hours...seems like 5 hours. That would be pretty low though. At one point, Kubota recommended limited use for the first 50 hours. I...

The reason there’s no diesel option for the small tractors is cost. Or, I should really say price. It would make the unit several thousand dollars more expensive, which would be uncompetitive in many ways. When I bought my first 425 twenty years ago, it was $8500. Now, I see it is $16,000. Heck...

Okay, this question has been asked many times and there’s a lot of content in the archives. However, the problem with forums is the content is difficult to find without spending a lot of time browsing the search results. So, here’s my comment. I first bought a 425. I liked it so much, I wanted...

I think emission regulations forced carb changes, making them more sensitive to contamination. I have three Honda engines and ALL run rough (surging at idle). I've cleaned those carbs so many times that I just ignore it. On some engines, a little extra choke helps them to run better. I...

I realize this thread is solved. However, a stuck fuel cutoff solenoid on the carburetor will also cause this problem, for any future troubleshooters. It lets just enough fuel in to start and run, but not enough to keep running. I found this problem on one of my machines, even though I put...

BTW, can you PLEASE take some pictures of your engine compartment, from different angles if possible? I really want to see the layout. This sounds like a fantastic machine.

Well, thinking about this for a second, if the front wheel motor can take the 1200 lb. rating, then adding 250 lbs to the rear would be nothing. PT uses the same motors front and rear. White (or whoever owns them now, I forgot) makes this series wheel motor with heavy duty bearings. I bought...

That’s just a bit over 3% increase per year, compounded. Frankly, it's not an unreasonable increase. Still, $16K for just the machine with a small HP gas motor does seem a little expensive for some reason. You can get a nice Kioti HST tractor with loader for that price. I won't go over the...

On a standard tractor or the PT, I've always had to do as you say. You might try going to high RPMs with the auger slightly raised, once you reached final depth, to see if it will "throw" the dirt out. I think the problem is related to hole being bigger than the auger. As the dirt starts up...

That's because your tools require less maintenance. :)

I have a mini-x and compact track loader. Both are two speed. Tracking the mini-x at "high speed" can be challenging on anything but a smooth surface. If I was forced to have only one machine for digging and clearing operations, it would be the mini-x. It's amazing what they can do with...

One question...do you know the purpose of the capped fitting on top of the tram pump? Perhaps it's to connect a pressure gauge? Regarding magnets, make sure you get the "high temperature" neodymium magnets. One example is DX06SH at K&J Magnetics. Standard neodymium magnets start to degrade...

Agreed. Too bad they have such short lives.

That's interesting. I have two Dewalts and have never lost prime in ether. Maybe there's an air leak somewhere.

Thanks guys. Turns out, I have the correct filter. Apparently, the fit of this aftermarket filter is very tight around the inside, raised part at the bottom. My 89-year-old dad was willing to apply more force than me and it finally slipped on, when I was away from the tractor. He always...

I need to know the height of the air filter. As part of the carb cleaning, I took the old dirty filter off and threw it away a couple weeks ago. The new filter came in and it's too tall. I've double checked the part number and can't figure out what's wrong. The new filter is ~2.25" tall. A...

Hi Peter, In my opinion, these Power Tracs don't have enough cooling capacity. Once upon a time, I used my 1845 to mow my lawn/pasture. In the dry summer, I had to run back to the shop once every mowing job to blow out the oil radiator. And my yard is only 3 acres. I finally fabricated a...

I've had two of these Subaru-powered PT's. On the first one, the fuel solenoid at the carb leaked or failed and filled the engine with fuel. I took out the engine and threw it away (should have kept it for parts)...replaced with another brand. Filling the engine with fuel is a fairly common...

You beat me to it Peter. I started working on my post this am and got called away. :) You're right about the cylinders. Those gear pump assemblies are totally unfiltered, correct? Only the main VDP charge pump. So, any particles in the reservoir will make it into those circuits. On the...

Put a strong magnet where the metal fragments "pile up" in the tank. That's where the "swirl" from incoming hydraulic fluid allows the fragments to gather. You’re not going to like this next comment. I made a post, years ago, about creating a cheap "filter assembly" for the pump/motor...

It's oil (air) cooled. No coolant. Sounds like unburned fuel. Could be a number of causes. Does it still smoke bad after it's fully warmed up? Also...check your oil level in case you have a leaking injector.

I guess I should also mention...I'm replacing the seals because the bucket leaks downs VERY fast with a load. So fast that I'm reluctant to use the forks to pick up something heavy. I was always taught this type of leak down is caused by problems in the control valve, not cylinder seals as one...

Thanks for the comments. The cap is indeed smooth...and is made from Aluminum. Given the force required to remove them, I wonder if the cap could even be warped on removal. I have no idea as to what tool PT uses to tighten the cap at the factory. I also find it amusing that PT makes its own...

I need to replace the seals in my 425 lift cylinders. Last time (on another machine), I had to use a pipe wrench to take the cylinder caps off. A strap wrench would slip. Also, one of the vice grip chain wrenches for oil filters and other round objects slipped too. A pipe wrench leaves quite...

Anyone have pictures of the engine compartment of the gas-powered 1430? I'm curious to see what they did.

I have the plastic tank...

I'm in need of a new gas cap and wondered if anyone has replaced their gas cap with something better than the original design. Over the years, I've owned 3 different 425's and they all leaked gas from the cap. I understand one can run the tank half empty to address this problem (or, half full...

They added that hose to at least one generation of the 425 as well (I didn't mention it to avoid complicating the post as most 425's don't have it). I think they later went back to the old design on the 425. To be clear, it is possible, of course, to create a hydraulic circuit where the...

Terry told me to definitely use a wrench on both my machines (425 and 1845) and tighten it as tight as I could get it, when I inquired why PT hydraulic pumps fail so early. I think this is a very common problem that most PT owners don't know about. When I first got a PT, more than 20 years ago...

Imagine the rear wheels were moved 1 mile to the rear. The front wheels would barely move, verses the rear wheels, when making a hard turn. However, the front and rear wheel motors on PT's smaller tractors are directly connected on each side...e.g., the output from the left rear motor is the...

Moving the rear wheels would affect the geometry. On my machine, the rear wheels follows the front in the same track. Moving the wheels back means the front and rear are on different paths, since the pivot point is no longer centered, which would affects the hydraulics.

Getting back to this old post...if you look closely at this machine, it has been modified. Apparently, someone added the Kubota engine, elongated the tub and moved the rear wheels further back. This might explain why the hydraulic pump failed as this would change the geometry of the machine in...

When the oil is that cold, the pump can cavitate (create air bubbles) which will cause a lot of problems if done repeatedly. As others have said, let the tractor warm up for several minutes or use a tank heater. And by several minutes, I mean SEVERAL. Feel the hydro tank with your hand. If...

Personally, I would not buy a 2430. In my opinion, the backhoe is not sufficiently robust. Therefore, if you are looking at the 2430 because you want the backhoe (would use it a lot), I'd look at another machine. For occasional use, just rent a mini excavator. Some of your 425 attachments...

I researched this issue a few years ago and made a post on here somewhere. The bottom line...you want a fluid that has low viscosity when cold, if you start the tractor in cold conditions, in order to avoid pump cavitation. Frankly, this is the most important consideration. Based on the...

This... Moly is best for non-roller bearing surfaces...like on the arm of an excavator for example. Other greases are best for roller bearings, like found in the mower spindles for example.

For anyone with the robin engines (or even the Kohler)... On both my 425's, I took the time to install an electric fuel pump with a solenoid shut off valve (search amazon for: Advanced Fuel Components Gasoline Fuel Lock Off Valve 12 Volt Tractor Anti Drip). This isn't the valve on the...

Same here on 1845. In fact, they were cheaper from PT than many other sources I checked...seems like they were about $50 each. Please remember...going to a larger diameter wheel and tire will reduce the total torque available. The max travel speed will increase though. On the 1845, I found...

Moss, I think a lot (most?) small engines have that option as a native part of their design. I'm pretty sure this isn't a special option unless you want a screen with an appropriate cutout. But why go with another brand? Until relatively recently, EVERY larger commercial piece of equipment...

I thought PT was now offering a kit to make these swaps easy....

Number 4 is your biggest problem. With time, you can keep escalating the risk of destruction until it comes out or you ruin the head. But not if you need the tractor weekly. You can bust out an EZ out with a punch and lots of patience. Can’t hurt to hit it a few times to see what’s up. I’ve...

I recently threw away the Kohler that came out of my first PT (same engine you have). Was saving it for parts but got tired tripping over it. I assume you can't weld a nut to the broken stud? That's usually that best method as the heat tends to loosen the bolt as well. If that doesn't...

On my 1845, I was driving along mowing long lanes one day happy as could be. It was dusk and, on one run, I noticed this fog in the air. That's odd, I thought. Did the temperature change that rapidly...you know, dew point, science and stuff...to cause the instant fog in the low part of my...

Thanks for providing the price...I was wondering what that would cost. I might order one for safety reasons. I don't like a plastic tank, that leaks gas if someone fills it too full, sitting right next to a battery in a hot engine compartment. There's always oil soaked debris in the tub as...

The short answer is no. On small engines, the alternator is like a trickle charger. It produces enough to keep the engine running, for example, but that doesn't take much. The PTO solenoid is electromagnetically operated and the inrush current requirement is significant. If the battery is...

I assume the engine does not bog down when flipping the PTO switch. I also assume you know where the PTO valve is located in the engine compartment. 1. Check battery. A low battery will cause this behavior even though the tractor will still start and run fine. Power Trac batteries have a...

I have most of those attachments. The vast majority I got used or they came with a used tractor. Also, most of my attachments are for the 425. The experience may be different with a more powerful tractor. Buckets: All buckets are good (I have all of them including the utility grapple). I...

Anyone know what gas engine they are putting in the 1430? I currently own Kohler, Subaru and Generac engines. I vastly prefer the Kohler engine...at least the older Kohler horizontal engines used in the 425. I have one of these engines on an Exmark mower. Those engines can go up to 4000...

WOW! Looks like somebody at PT believes in the myth that engines like this need backpressure. This looks WAY too restricted to me. While a large header/exhaust pipe can reduce power at low RPM's due to reduced exhaust velocity and scavenging, a lot of back pressure is not needed in a 4-cycle...

Looking at your pictures again, your oil radiator doesn't look bad at all to me. If it's not leaking, it's not really likely to leak in the future. You can get a "fin comb" from Amazon to straighten those fins (e.g., Supco FCRH6). Unless there's something I'm not seeing in the photos, I'd be...

There's nothing special about the PT oil cooler. You can use a substitute IF it has the same or greater cooling capacity. Count the number of "pipes," pipe size, and overall dimensions. You should be able to get "close enough." You may even get a better cooler. The more cooling capacity...

A key purpose of the charge pump is also to cool the VDP. On larger tractors, like my 1845, the wheel motors also have a separate case drain for bypass and to help with cooling. Consequently, these circuits are not "pure" closed loop. A BIG downside of closed loop is the lack of any...

Agreed. If you have really low pressure, it's probably time.

Power-Tracs use a closed loop drive circuit. Oil in the drive circuit is not filtered and does not return to the tank (except for what bypasses and is made up by the charge pump). So, tank turns are not really an issue regarding the VDP. The charge pump is a gear pump. MossRoad (check out...

Somewhere on here, I did a calculation and write up about the HP needed for the 425 (I have two 425’s). It's been a while, but if I remember correctly, the 425 needs a full 25 HP when under a full load, such as mowing a slope for example. This makes sense as the 425 has a 25 HP engine, right...

I have 8 hydrostatic machines and the L3901 is the loudest BY FAR. Frankly, this is a design fault on the part of Kubota. There's a number of well known ways engineers can reduce hydraulic noise. That said, I wear headphones on all my machines so I guess it's not a big deal in the end.

I was able to dig the tractor out yesterday and do some tests. Placing the tractor on a dirt pad I had leveled with another machine, I was able to get it to spin the tires in low range at 2000 RPMs (I didn't test any RPMs lower than 2000). Placing the tractor in midrange, it would not spin the...

Thanks for all the comments guys. I still haven't had a chance to dig the L3901 out of the barn yet (it's stuck behind some other equipment) and I had some family issues to deal with this week. As to some of the other questions... The tractor has about 100 hours (I'll update) and I did the 50...

I totally get what you are saying, with a little caveat...stick with me. A hydrostatic tractor has the "equivalent" of first gear. That occurs when you're applying just a little tram. Under that condition, the pistons in the variable displacement pump move just a small amount of hydraulic oil...

To answer some comments: I have R4 tires and run the machine at 2800 RPM's (max power) most of the time. Four filled tires plus a heavy tiller and a bucket does add a lot of weight and may be impacting my experience. I'm pretty sure the tractor would spin everything with unfilled tires and...

My tires are filled and I keep the tractor in 4wd all the time along with a tiller on the back for counterweight. It does NOT want to spin the wheels in low, never mind mid-range. I've had a few times digging soft dirt (wash near my creek) and it didn't want to spin the tires at all in low...

It seems to be only transmission related. If I put a heavy load on the front bucket, the steering is a bit "jerky" if I'm not moving. But that is normal per my local Kubota dealer.

Well, this isn't a fair test. I'm talking about normal operating conditions. Not setting up an extreme test where I "know" it will fail. However, you may be right that my experience is normal. Do you have an L series tractor? If so, can you use it for most normal work in mid-range? I can't...

I have several hydrostatic machines and I'm fully familiar with how hydrostatic machines work. I bought an L3901 a couple year ago and haven't used it too much (because, as noted, I have other machines). However, this year, I got the tractor out and it was time to see what it would do. Which...

I have an L3901 and don't like the water separator. To remove the water, I have to remove the bowl and poor the contents into something. On all my other machines, there's a valve on the bottom of the bowl. It's simple and quick to open the valve and drain the water. Is anyone aware of an...

If you have a new PT-425, it would be great if you could post a few pictures of the engine compartment and pump arrangement. The picture below really caught my attention. In addition to the Kohler engine, it looks like they may have gone to a metal gas tank, added a water separator, and put...

Most of you probably know this...but I didn't.... I've noticed PT talking about measuring charge pump pressure to get an indication of the "health" of the variable displacement pump (VDP). As most know, a charge pump provides "make up oil" to VDP to avoid cavitation in a closed loop system...

So I finally got around to installing my four new larger capacity wheel motors on the 425 (it's a long story I'll detail later with pictures). However, the right front motor has a "clicking" sound at a certain point in its rotation. This sound is three very rapid clicks. The other motors may...

Symptoms...starter would not engage at times. Ken...not sure...looks the same I guess. Tom

Starting a new thread to make this issue more discoverable. The starter problem is a known issue with certain 18xx units. Something about a slight voltage drop in the original wiring design. PT makes a "kit" to fix the problem. The kit is basically a standard auto parts store solenoid...

As discussed numerous times, the wheel motor circuit is closed loop. So, when replacing a wheel motor, air can be introduced to the circuit. I assume there's a way for the air to be automatically purged by the VDP, probably by the charge pump circuit. Does anyone know how this works? I once...

So, I'm getting things together to put the Subaru 35 in the 425. I've seen other equipment use rubber motor mounts under the engine. In addition to the vibration damping, I've read this is done to extend bearing life in the engine. Anyone have thoughts or knowledge of this issue? Tom

You guys may recall my thread, a few months ago, about the death of my Subaru. The root cause was gas in the oil. Seems to be happening a lot lately. I didn't bother tracking down the exact source of the leak. I suspect it was the carburetor but I don't know for sure. By the way, I still...

Taian Dongyue Carrying Machinery Co., Ltd. - Multifunctional Wheel Loader Looks like a copy of the Avant/Multione. The quote for the 50HP model, DY1150, is $19,500. Telescoping boom, Kubota/Perkins engine, rear hydraulics with 3-point hitch option, etc... Very cool. I wonder if one of the...

I wanted to send my variable displacement pump back to PT for testing since I have the engine out. I have a bunch of JIC plugs and caps. So, I power washed everything and started the process. I first tried to remove the rear PTO pumps since I wasn't sending these back. In the picture below...

I recently blew a hose on my 1845. Unfortunately, it blew at the exact wrong moment, as luck would have it. I was sitting crossways in a road blocking traffic. So I had to quickly move the tractor out of the way. And, unfortunately, I wasn't home and didn't have time to research the tow...

I called Terry and my engine is shot. Less than 500 hours. :( So, go with a 28HP EFI (really, a 25HP at 3600 RPMs) or upgrade to a bad boy 35HP Robin? Frankly, I'm a little scared of the 35...BUT...I see a lot of advantages as well. I think this should be a fairly safe upgrade. I'll be...

Was running my tractor a bit yesterday and it wasn't acting right, even though then engine wasn't hot yet (i.e., not the infamous vapor lock issue). I only used it for about 15 minutes. I went to crank it today and the engine wouldn't turn over at first. It finally turned over and started but...

I'm looking at Kubota RTV's and noticed a rather long thread about excessive play in the suspension. New units at the dealer where known to exhibit this problem. Is this fixed now? It seems Kubota ether hasn't responded, or said they were "working as designed." I'm getting an 1120 demo...

I'd like to buy my father a UTV. He's 80 and lives with my Aunt, who's 70. The number one criteria is easy access. A lot of UTV's strap you in like a formula one car. Although they're both in good physical health, that won't work for them. Any recommendations? P.S...a golf cart would...

I received a Gravely 5660 with a property I purchased and gave it a try yesterday. It's got a brush mower on the front. While the tractor cut well, I found it very hard to use. The front would "ride up" while mowing forward. I had to lift up on the handles all the time while mowing to do a...

One of the odd things, to me at least, is the Power Trac showroom. While the room is great, the products on display almost look like rejects. Very ugly welds, cut out mistakes, running paint. Every time I visit that showroom I'm unimpressed with the workmanship. A lot of the stuff seriously...

Power-Trac is having an overstock sale. Ten percent off tractors and 15% off attachments. You don't have to buy a tractor to get the discount on attachments. Check their website for details.

I called B&P and had an interesting discussion with one of their engineers. Here's a few highlights for the knowledge base: + My older, new generation 425 has the 21cc M4PV21 pump, not the NT10 pump. The NT10 is now discontinued. + He strongly recommended the use of hydraulic fluid (46AW or...

I'm about to upgrade my White 14.2ci wheel motors with White 21.2ci (or bigger) motors. Any way to easily figure out the speed changes? The current motors are very fast. I'd guess 10 MPH. The tractor is faster than my 1845 and I have larger than normal tires on that tractor. I'd rather have...

I was reading recently that adding a 2 micron filter will double the life of hydraulic motors and pumps, compared to a 10 micron filter. So, I'm back to the idea of adding a filter to the PTO. This wouldn't be a permanent installation. I would imagine hooking it up periodically. I know this...

Ok, let's talk UTF once again. At least for the Bondioli & Pavesi NT10 pump used in the 425. This pump is optimized for a hydraulic viscosity range of 15 - 35 cSt (mm2/s). Of course, you cannot talk about viscosity without talking about the associated temperature. Most viscosity ratings are...

I need to add some additional dust plugs and caps to the quick connect couplers. Anyone know the correct size for the PTO and Quick Attach couplers for a 425?

On my original Moss Road Vintage (MRV) 425, I don't recall being able to stall the engine using the tram. However, I would usually back off, since this is poor technique and causes pump cavitation, so I can't say for sure. But, my 13 year old vague recollection is the tractor would lug way...

Since I was out with the camera today, I thought I'd post a few pictures. The machine: Another view: Some steering protection to keep a little dust and mud off the shaft. The rear "dust catcher." Debris will gather on the outside near the intake. This forces the machine to draw air...

To keep from hijacking the other thread, I started a new one. I have an older machine with the cable. I can watch the cable move on the pump. So, I'll push the cable forward slightly (or backward, doesn't matter) then stop, in about a second, the machine will lunge. It's almost like pressure...

I remember when Kubota first launched their diesel ZTR's several years ago they had a lot of problems. If I remember correctly, the combined pump and motor arrangement was failing. Particularly on hills (maybe starving the pump leading to cavitation? don't remember the full story). My...

I have an 1845 that I once used for mowing (before I wised up and bought a used Exmark). Like many others here, I had a lot of problems with overheating. I eventually screened the entire inside of the hood and created a type of "prefilter" for the rear that largely addressed the problem. By...

Does anyone know if the Robin engine is the same physical size as the Kohler engines Power Trac used previously. As luck would have it, I have a 25 HP Kohler in my garage that came out of a 2002ish vintage 425 (I bought the tractor originally and sold it to my neighbor when I bought my 1845)...

Well, I took my trip to Tazwell last week. Terry had a 425 and 1430 lined up for testing. Keep in my...I owned a 425 for 2 years (2002 model) and currently have an 1845. The 1845 has the same "front section" as the 1430 and most attachments are interchangeable. Here are my impressions...

I was reading back through the archives and noticed PT was working on a 430 using a Kohler fuel injected engine and the 1430 wheel motors. Any idea what happened to this tractor? It seems like the perfect compromise.

I bought a new 425 around 2001 and used it for a year or so before selling the tractor to my neighbor. It was a great little machine but I needed more power for the projects I was tackling then. I "upgraded" to an 1845 and haven't looked back. However, I recently purchased some land that's...

I recently purchased a 12KW stationary backup generator. I need to connect it to my 1000 gallon buried propane tank. I want to connect this myself and have already pulled the permits. I'm thinking of installing a T at the tank, then running a new dedicated line to the generator, which is...

Ok, here's a dumb question for you. How bad do MIG welders stink? I've never been around a welder but I have a need for one. I was thinking about picking up a MIG welder and learning how to weld. However, I understand they are very sensitive to wind and I live in a very windy area. So, I...

I spent the day replacing my well pump. The pump is at 240 feet and the static water level is 50 feet. I also installed a sand separator. The pump runs, but no water. I suspect it's air locked. Any ideas? I hate the idea of pulling it again.

It's time to replace the hydraulic filter on my 1845 and I can't find my manual. Also, I can't remember where to connect the host to bleed air from the variable displacement pump. Do I connect to the "T fitting" at the top of the pump as shown in the image below?

Thinking about ordering one but was wondering if this issue was ever resolved. Sent a email to them but never received a response.

I'm looking at a 2005 zd25. The right side drive is "sluggish" and hesitates when trying to move forward. If the tractor is cold, it will even stall the engine. I seem to remember that some of the earlier Kubota ZTR's had a hydraulics problem. Any ideas as to the cause and possible fix?

Neighbor has a Ford 2000 and the lift only goes up a couple feet. It will maintain this level, but won't go any higher. Any ideas as to the cause? Could he have the draft control in the wrong position?

Is anyone importing Chinese 2 wheel tractors to the US? I'd love to have a BCS but can't justify it for a "vegetable garden". But the Chinese have a lot of 2 wheel tractor designs. Someone must be importing them (if the engines can pass EPA).

Does anyone import those Chinese 2 wheel tractors that are so common over there? I'm talking about the type that looks like a BCS or old Gravely.

I've read several times on this forum that the PT uses a "closed loop" drive system. I asked terry about this once and he denied it. In any case, how could it be true? The hose coming from the filter is huge. If it was only feeding the charge pump, and only make up fluid at that, why so big...

My father is looking at a used Kubota 1700. Unfortunately, he often calls me for pricing help but doesn't get the proper details to make an accurate assessment. Here's what I know... Year: don't know, but it has ROPS and Power Steering Hours: 900ish Transmission: Shuttle Shift Visual...

Occasionally, when I stop and try to move forward/backward slowly, nothing happens when I slightly push the treadle. If I push the treadle a little more, then the tractor will lunge forward/backward. The behavior is similar to when you first start the tractor and need to energize the break...

I'm building a 30" x 36" pole barn style garage. There are 26 posts in total. My question...do I need to anchor the posts to their concrete pads? The posts are all just sitting on their respective pads (to minimize rot) and will have, on average, about 18" of fill. I'm a little concerned...

What's the "best practice" for setting posts for a pole barn. I'd like to set the posts on a concrete pier but it's too much work. Instead, can I just pour a nice pad, set the posts, and fill the hole with gravel around the posts? I assume gravel would be better than dirt because of better...

I rented a small articulated vibrating roller to level a pole barn pad. It uses a Honda engine and variable volume pump. I took a picuture of the engine compartment in case anyone might be curious. Very neat and clean set up.

I've roughed out a site for a pole barn to store my tractor and for a shop. The lower side of the site is about 7 inches lower than the upper side (side 2 in the attached picture is 7 inches lower than side 1). I'm thinking of using gravel to make up the difference when I go to pour the pad...

Twice in the last few months, I've had the VV pump bolts fail. The second time, I replaced the grade 5 bolts with grade 8...and they failed in less than 50 hours (too brittle I suppose). The only warning sign was additional vibration. Everything continued to work fine. There's a lot of...

When I first got my 425, I was a little disappointed with its digging ability. One day, I decided to attach the "Potato Digger" plow to loosen the dirt first. This worked great and I had no problem digging out several FEET of dirt for a new deck project. Recently, I needed to level a pad for...

I need to put up a pole barn to store my tractor. I have a couple questions as follows: + I ordered a nice set of plans. However, the plans have a pole right in the middle of the floor. I don't like that. Anyone know a source for plans with the poles only around the perimeter? + What's the...

I don't see why people think Power Tracs are cheaper than regular tractors. When I was first considering the 425, my next choice was a Kubota BX series because of similar size, stability on hills, 4WD, etc? Comparing the 425 to the BX, and going by current prices, by the time you put a bucket...

I want to add a bypass filter to add more filtration. However, I always delay because I don't know where to tap into a circuit. Looking through the service manual, I saw a page for the tilt seat. I took the tilt seat off my 1845 because I didn’t like it much. I just connected the two hoses...

Anyone know of a source for dust caps for Flat Face hydraulic couplers? No one seems to offer the dust caps because most people don't use them (or so I was told by a hydraulics supplier). However, they are still recommend by Parker and others. I've been collecting these couplers off ebay and...

Edit: I accidentally hit return before I finished typing the Title ("Quick Attach Bolt On"). Apparently, there's no way to edit titles. I have an extra Quick Attach plate and I want to bolt on a trailer receiver hitch. However, I’m concerned that the bolt heads will stick out too far in the...

While mowing, I discovered an oil leak around the right rear wheel motor area. I guess I’m lucky…this is my first oil leak. I thought it was the wheel motor for sure and called Terry. Since I’m not getting any oil around the hub on the outside of the tractor – only inside the tub – Terry said...

Anyone know the maximum pressure to the wheel motors? I'm talk about the point where the release valves kick in.

Anyone know where I can buy these for a reasonable price? I just need the rear tires and wheels, but I need a total of four (2 rights and 2 lefts). Thanks.

Scott\'s mower won\'t go.... I have a 2001 John Deere manufactured Scott’s mower (S2348). I’m having an intermittent problem. Sometimes, when I crank the mower and let the brake off, the engine quits. If I push the brake back in, the engine will catch back and run. I thought the safety...

Anyone know a source for wheels for the 1845? I run duals now but want to move to singles (26x12x12). I've got two ruined tires at the moment so it's a good time to move up to 6 ply turf tires.

When I bought my first PT, I got about 150 hours on the steering cylinder seals before I had to rebuild both cylinders. The steering got progressively worse until I had to move the steering wheel quickly, or run the engine at full RPM, to steer. I have an 1845 now and with just over 150 hours...

Inspired by Sedgewood's example, and YAFOMPTM (Yet Another Flat On My Power Trac Mower), I decided to address this problem once and for all (I hope). After an exhaustive search, I discovered the tires in the Attachment. I ordered...they arrived three days later. I'll try them this weekend...

I think we need a politics forum on this site. I certainly come here to read about a lot more than just tractors. I come here to read about Pole Barns, Welders, Rural Living, etc.... I know that political issues get heated and may drive some people away. But if we had a Politics forum, the...

My tractor has a three post starter relay like the one in the picture below. The small post in the middle goes to the starter solinoid. I ordered a new one and they sent me a four post relay. One small post going to the starter solonoid and one going to the ignition. Can I still use this...

\"Dig-It\" Tow Behind Hoe Anyone own or have experience with one these? If so, any comments, good or bad. Thanks.

For a while now, I’ve been thinking about getting a backhoe. I don’t have time to build one from a kit and I need one now more that ever. The PT hoes seem to be reasonable priced. So…does anyone know if the PT hoes, for the 2430 for example, will fit a standard universal skid steer quick...

Anyone know the series of couplers that PT uses (i.e., 60 series, 4000 series, 6600 series, etc) for the aux PTO? I think they are Italian made buy I can't find the brand. I also wonder if they are metric. PT tends to find esoteric parts that can't be easily ordered online so I wouldn't be...

When I get a larger PT, I would like to explore the option of adding a Skid Steer Universal Quick Attach system to the tractor. Advantages include the ability to choose from a much wider variety of attachments and manufactures, a ready market for used attachments to buy or sell, and the ability...

I've never been very happy with the quality of the PT hydraulic oil breather cap. I'm concerned this cap could let in too much contamination (particularly water contamination). Anyone know of a better breather cap (the ¼ turn variety)? I know there are some good threaded caps available...

I’m interested to get some opinions on the differences between the 1445 and the 1845. I seem to recall that someone (Charlie or Sedgewood?) was trying to gather some data to compare the two tractors. Besides the obvious differences, such as dual wheels and tilt seat on the 1845, some of the...

RegL or iono, how's it coming with the 1430? Seems like there are few Power-Trac 1430 owners on this site and I would be interested in your experiences to date. For example, how's the power of the tractor compared to your expectations? Any surprises (besides the corrupted fuel tank)...

PT has a used 1430 on their site with less than 100 hours for only $12K including a bucket and mower. Also has a new engine. Seems like a pretty good deal to me. Anyone know the story behind this tractor. The "new engine" at only 100 hours seems a little suspicious.

Take a look at the attached picture of the engine cover on the new 425. It looks different than my engine cover. And, what is the item visible in the engine compartment? I don't think it's the gas tank because its too low.

I’m building a new deck on my house. Due to the complexity of the design, I am building part of the deck on a temporary structure. This will allow me to suspend the deck posts of their holes and pour concrete up to the bottom of the post. This makes getting the post in exactly the right spot...

Navigate over to the PT site and click on the "photos" section. They have some new photos and even have an “actual” picture of the 1445. As I suspected, they are using photos of the 1460 in the area of the site that talks about the 1445. PT doesn't seem to pay much attention to these types of...

Over the weekend, I was able to test drive a very nice 1430. The machine is 3 years old but only has a little over 300 hours. My impressions: Good - Noise: I expected the unit to be much louder than my 425. This was not my experience. I used the machine for about an hour. I feel both are...

This may have been discussed b/f but here goes.... I know PT does not recommend filled tires for the 400 series. But what about the 1400 and larger series?

For some time now, I've wanted a wing mower. I have almost exactly 3 acres to mow. And I don't particularly like to mow. Consider it a waste of time. It was taking almost 3 hours to mow, including a break. With the wing mower, its down to about 1 hour and 15 minutes. I think I can get it...

As posted earlier, I’m seriously thinking about upgrading to a 1430. I am arranging a visit to PT in the next couple of weeks (btw, they are closed the week of the 4th again this year) to test-drive the 1430. Therefore, I will probably want to sell my 425 and most attachments. However, I have...

I've been thinking for a while about upgrading to something a little bigger than the 425. When I first bought the 425, I envisioned using it primarily as a lawn mower with the ability to do a few other tasks occasionally. Instead, I have tackled a host of new projects that would benefit from a...

60\" Mower Blade Tip Speed. I remember a conversation several months ago about the hypothetical blade tip speed of the Power-Trac 60" mower. As part of the belt post, I looked up the speed of the Gresen motor at 8 rpm. I believe this speed to be 3187 RPMs based on 1000 RPMs for each 2.51 GPMs...

I want to purchase a 10’ dump trailer to use around the house and to bring in mulch and stuff. I checked the price on the 10’ “economy” model EZDUMPER and was amazed to find it was over $3600. That’s more than I can afford and I don’t have the welding skills, or welder for that matter, to make...

Over the weekend, I decided to take one on the 60” mower spindles off to see if I could determine where all the grease goes. Before I mow my three acres, I always grease the spindles and it takes 10-12 “pumps” of the grease gun. That’s a lot of grease. I couldn’t determine where the grease...

We had nice weather this past weekend so I decided to do the 75 hour tune-up to get ready for summer. I say 75 hours because I use a more aggressive schedule than PT recommends. First, I gave the tractor a good bath. Then I changed the oil and filter, air filter, fuel filter, and hydraulic...

I have attached a small spreadsheet I created to compare the different PT models. Specifically, I wanted to compare HP and Torque ratings for each tractor, by the weight of the tractor. I was trying to get an understanding of how powerful a given tractor would be for its weight. For example...

Since I have a Cold this weekend, I decided to spend a little time and spec out the tractors I intend to build when I get my new welder ( yeah, right). Here are the specifications (see the attachments for drawings): TomCat T1 Engine: Briggs and Stratton Vanguard 26.5 HP Diesel (made by...

Almost no posts this weekend. Come on guys. OK. Here's what I did with my PT this weekend. With all the bad news, I find that seat time is a wonderful way to take your mind off things you can do nothing about. So, I decided to do a little maintenance on the PT. Now that I have the tach...

I want to build a detached garage with a basement. For reasons I won’t go into here, I would like to keep the visible footprint of the garage as small as possible while having the most space available. One idea is to build a 24’ X 24’ garage with a full basement. However, I would like the...

I bought a new “spec. home” from a builder about a year ago. At that time, I had the house checked for Radon. The house had a Radon reading that was ten times the recommended level so I had a fan installed that pulls air from below the basement slab. I’m now in the process of finishing the...

Can someone with a Kohler CH25 Service Manual please post the length, height, and width of the engine. I can't find my manual. Tx.

What are the \"US\" models I'm sure this has been asked before, but I did not find the info when I search the archive. My question is: What are the Yanmar models that were imported by Yanmar into the US? I'm not talking about the conversion of grey market to US model numbers. I'm talking...

Anyone tried the PT Backhoe? I’ve got quite a few trenches to dig and a small backhoe would be handy. I remember a couple folks had purchased the Lackender hoe. I was wondering if the PT hoe might be better suited to a 425’s hydraulics. Also, has anyone figured out how to install a better...

What\'s wrong with this idea 2.0 Ok. So I wouldn’t mind adding a wing mower and an engine to the PT mower as bubenberg has suggested. However, I have a slight modification on this idea. I want to buy an engine and hydraulic pump from Northern Tool. I will then buy another std PT mower and...

Given the winter weather, I thought it would be a good time to start work on finishing my basement. My Furnace, Hot Water Heater, Water Filter, and Water Tank are all located next to the stairs. I would obviously like to enclose these items behind a wall. However, I need to have sufficient...

I have a relatively new house (2yrs old) with a well. We have always had a problem with sediment in the water. The house has a rather large (20” “Big Blue”) sediment filter on the line coming in from the well. However, even this filter isn't large enough as I have to replace the cartridge...

I would like to learn how to weld in order to create some of my own implements and for other projects. Without going into a lot of detail, I need a welder the will weld 1/4” to 5/16” mild steel. I wouldn’t be welding stainless steel, aluminum, or any exotic metals. I have never welded...

One of the things that concerned me originally about purchasing a Power Trac, is the lack of a robust market for used machines. If Power Trac distributed their product through a traditional dealer base, then such a market would automatically exist. However, since these tractors are only...

Thought I would finally get around to posting a couple of pictures. This first picture is of the extra lights I mounted on the canopy. I ran the wires inside the canopy “pipes” because I frequently put my hand on these pipes to brace myself on hills or to just rest my arm. I first drilled a...

The more I use my PT 425, the more I appreciate the elegance and simplicity of the design. This got me thinking (or fantasizing if you want) about designing the ultimate PT. Here are some preview specifications: - Engine: Water Cooled Kubota Diesel. Air cooled engines run too hot in the...

Besides bubenburg, has anyone else tried a wing mower? I loaded up about 400 lbs of concrete bags and gravel in my trailer and pulled it around to simulate the addition of a wing power. Seemed to work fine. I could barely tell the weight was back there. I’m thinking about getting one of...

Has anyone tried different governor settings? Sunday, when mowing, I decided to move the governor spring toward the air cleaner to experiment with some of the “more sensitive” governor settings. Power Trac’s ship with the governor spring in the “least sensitive” setting. While this ensures...

Anyone replaced their seat yet? The standard PT seat could use a little more cushioning or even a suspension. I have been looking through the Northern Tool catalog at seats but I can’t decide. Since there isn’t a Northern store near me, it will also be a hassle to return if I buy one that...

Being Caucasian Isn\'t Worth The Risk. For some time, I have been researching the issue of race. I’m thinking about getting a new job and moving to California, so I’m ready for a change. I have carefully considered the Big 3, Caucasian, African American, and Hispanic. In the end I have...

If you lift a heavy attachment, like the mower for example, to full height and turn the engine off, how long does it take for the hydraulics to leak down and for the mower to settle to the ground? I originally wanted to build a platform I could use with the fork lift attachment when working...

First, the Blades. I’m thinking about putting a different set of blades on my PT to experiment. Does anyone know the tradeoffs between different types of blade combinations (i.e., high lift vs low lift, gator blades vs standard blades, dual blades vs single blades, etc…). I wonder if the PT...

I’ve noticed that I gather a tremendous amount of dust on my PT every time I use it. Therefore, I was considering an upgrade to the extreme duty air cleaner for the Kohler. However, in surfing around, I found a couple “precleaner” sites that make some interesting claims. Anyone used one of...

I checked the oil when I first got my PT425 and it was only about half way up on the dip stick. By hour 6, it was at the bottom of the stick. I filled it back to the top and, so far, it appears to be staying there for the last couple of hours. What is the “normal” oil use? Hans, how much oil...

While I’m in the posting mood today, since I can’t drive my tractor , I thought I’d fill you in on what I believe is a new muffler design for the PT425. In the past, I think 425’s had rear discharge mufflers. Take a look at the attached picture. As you can see, this is a side discharge...

Since I’ve had my PT425 about a week now, I thought I would post some observations. Background I have about 3.2 acres of lawn and pasture. There are some small hills and a few rough areas. The lot has no trees and my primary tractor activity will be mowing. I looked at both the PT and BX2000...

Well, I finally pulled the trigger and bought a new PT. I’ve had the tractor about a week and, overall, I’m very impressed. However, with a grand total of 3 hours on the tractor, I’ve had a few problems: Hour Meter Not Working: called PT and they said to take the front plate off and plug it...

I suspect this topic has been discussed before but, if so, I can’t find it using the search function. My question is a simple one…what is the safest method to store gasoline. Currently, I have several cans of gasoline setting in my garage. This can’t be safe. I have seen storage cabinets for...

Couple of questions about the PT1430: - What is the top speed? Web site says 12 MPH but I thought I read somewhere else that is was 8 or 9. - Will any 400 series attachments fit the 1400 series? Is the quick attach a different size? Some of the 400 attachments are less than 50% the price...

Mossroad, when testing a PT422 at the factory, I noted the joystick sensitivity you mentioned on your web site review. This sensitivity “slowed me down” as I was always correcting/overcorrecting the adjustments. I know with experience this issue would be partially mitigated. Also, reducing...

Carpenter, I notice you have the cement mixer attachment. Do you use it much? What is your opinion of it? Have you found any uses besides mixing cement (i.e., watering trees, mixing potting soil or feed, mixing cake mix for really large cakes). I’m looking for an excuse to buy this...

Saw this article on the web. Don't know if he finished. BOISE, Idaho (AP) - Gary Hatter is riding a bright orange Kubota BX2200 lawn mower into the record books. He started his cross-country odyssey more than three months ago in Portland, Maine and spent Thursday night in Boise before heading...

Does anyone own (or considered/tested) a PT2422? If so, would you mind posting your impressions? TX.

OK Mark. I’m dying to know. After reading about endless modifications to Kubota’s, Earth Force’s, and 7-11 coffee cups, what truck do you run? I will go ahead and state, for the record, that I think it’s something with a Cummins I-6 engine, as you would naturally appreciate the perfect...

Anyone priced a BX2000 lately? I have a sneaking suspicion there was a small price increase in May. Anyway, I just priced a BX2200, 60” MMM, FEL, and filled rear tires for $12,000, before taxes, from my local dealer. This is after much negotiating. Carver has a great deal right now on his...

Trescrows, I really respect your comments. I made a post over on the Other Brands thread about the BX2200 versus a Power Trac 425. If you would take a look at that discussion and post any comments you may have, I would appreciate it.

Well, I finally got CFO approval for a new tractor. My tractor will now effectively cost twice as much, but that’s a another story. Unless something drastic happens when I visit a couple of dealers this weekend, it’s down to a PT425 vs. a BX2200. Here’s my analysis: Background: I have...

I’m considering a TC18 or TC21 with FEL and rear discharge MMM. Anyone have prices on this combination?

I’m just beginning to look at the Boomer line and am curious about reliability. Anyone have any comments on the reliability of the TC18 and/or TC21 models. I have seen a couple comments on other models (steering rebuilds, transmission recalls, sticking thermostats, etc…) that give me a little...
