Lead/acid batteries still work just fine. AGMs are pretty much the same sort of lead/acid batteries. The only difference is the way the acid is contained between the plates in AGMs makes it easier to keep the acid and fumes inside the battery. My 2 cents says the AGM is worth the extra cost...

I hear you. I like the inexpensive AGMs for all of the same reasons, though I don't agree with the idea tha the plates fall over. If you look at how they are built, they cannot. Still, whatever the reason the AGMs do seem more durable against vibration and impact. Maybe the adsorbant pads...

"Slow when cold" tractor hydraulics are often a clogged sump strainer or hydraulic filter combined with trans/hydraulic fluid that is too viscous at cold temperatures.

I think you got the best tractor. Congrats We don't have a good idea which one you have without you trying it and telling us how it works. Reason for that is that there isn't clear agreement on how either one is defined. What matters is that your tractor already has something which will work...

Yes. That's by far the best way. Unscrew the flange connections at the ends of the steel lines and the hose will bend enough so you can take the whole piece down to the hydaulic shop. There they will use high pressure crimp connectors to fasten a new piece of hose in place.

We used to have a lot of porcupines in the pine forests in Colorado. You could always see a few on a hike. We had to teach the dogs to leave them alone - and a quilling often meant a trip to the vet. I haven't seen a porcupine now in 30 years or more, and our vet says he hasn't either. When we...

Nicely said. Next time I'm in a tractor buyng mood you can bet I will be stopping by to see you. rScotty

How important is the mid-mount mower to you? And if the 755 has a hydraulic leak is that a problem you would fix or take it somewhere? I would need to find out more about the leak before considering this one - and I am a mechanic. I do like 755s, but wonder if parts are as easy as the rest of...

First of all I am going to begin with splitting the margin down the middle - half to each. Now we can start in on the fun part of haggling over the all-important little extra things. Having taken care of basic list price for the tractor by splitting the margin. What kind of discount can we do...

I figure that the salesman and I both want the same thing, we both want me to buy their tractor. So since we have the same goal, that puts us on the same team. Now we can get down to making it possible.

I expect the sales person to be on both sides. We know he is working for the Dealership, but if he is not also working for me then I will simply go somewhere else. How he reconciles those competing loyalties is what makes him a salesman. I don't mind haggling - in fact I enjoy it - but it has...

I have gauge wheels on a rake, but they have problems too. You may want to consider simply makng some two foot long 4x4 angle iron with an up turned ski front and bolting them to the outsides walls of the box blade. I've been meaning to do that myself. It would be easy to do, inexpensive, and...

Nor would I. Whatever that L48 seller is doing is not the buyer's market we were talking about - which is a buyers market in anything - houses, cars, trucks, boats, or tractors that only need simple repairs like an engine rebuild, or new hydraulics. Those are the ones that are going for bargain...

You are so right... Hardly a day goes by that I don't get a card or letter, or an unsolicited sales pitch on the phone by some cold-caller wanting to buy my property or house. Probably eveyone else here on TBN gets the same time-wasting solicitations too. But in the last ten years exactly one...

Seems like you are still concerned, so here is the "Rest of the Story". The truth is that Kubota never has been very knowledgeable or forthright about their UDT types of Oil. The early UDT and Super-UDT - which later became SUDT - were well known for making HST transmission noisy. I know my...

I think the best link for yours was in post #19 by "beenthere". Real nice diagrams for the JD650. BTW, that link wouldn't work on Safari, but linked up fine on Google. Interesting to compare the same mechanism from Yanmar and JD. The similarities are a lesson all in themselves. rScotty

Who knows? What kind? But I'll say this about used tractors....If you are not able to make an accurate guess about the mechanical condition & an estimate for the inevitable repairs, best stay away from it. Don't even waste your time. The other side to that story is for a person willing to...

Very nice. Thanks. There's nothing like seeing it with your own eyes. Kitchen looks pretty good for thermal. Interesting shot. Do you have to adjust the offset between visual and IR images?

I'm betting it is one of the switch adjustments. On our Kubota M59, there are times when I can start the engine with the seat reversed and the hand brake off....and times when it wont crank unless the hand brake is on and the seat "reset" as well. It doesn't make sense to me....but somehow the...

Cars are shaped to sit outside and shed water, but tractors and implements seem to collect the rain. I use the old fashioned waxed cotton tarps. Tied down all around, and skirt high....not touching the ground lets air flow under them. They last for 3 or 4 years.

No, there is still a 2000 lb difference. Looking at the overall frame construction and the thickness of metal and fastenings will give an idea of were the extra metal was used. The M62 loader lifts nearly twice the weight & the TLB is set up to handle loader stress. They seem to be differently...

Can you post some images? What's comparable in iPHONE/iOS?

I don't know technically how any of the desulfate cycles work. If anyone knows, I'd love to hear how it works. Apparently some desulfators are different than others. For the last 15 years we've used BatteryMINDer type chargers just because they were the first I saw with a desulfate cycle &...

No, but they do make a tractor built even heavier than a FARM tractor, and it does have a six speed HST. It's the M62 with 6 speed HST+ tranny, weighing in at about 8000 lbs. It's basically a heavily built low profile TLB for medium duty commercial use. It can be ordered with the 3pt hitch...

I don't have a JD650 book, but here are some from a possibly similar Yanmar model. They are what I would be looking for if I was doing this job. The parts #23 to 29 in the dotted inset 11 show the lowering valve. That could be your problem if yours is stuck. It's a valve very much like any...

I'd flush repeatedly with a very high detergent low viscosity motor oil. My reasoning is that you know regular motor oil is far better than the water mix that was in there, and nothing in the motor oil will hurt the hydraulics. In fact, a number of commercial JD machines use motor oil as their...

Do what he says and also look again in the manual. Do you have parts or workshop manual? That 3pt lowering speed valve can be removed entire and it has O rings too. They get old and need replacemet. Easy job, but look at the exploded diagram first. The O ring on the lift cylinder piston...

There is a drop speed regulator under the front of the seat. It is a needle valve that will control drop speed of an implement ...but not raising speed. Have you worked with that? If you raise up the 3pt arms and put weight on the arms, turning in that valve clockwise should slow and then...

We need more information. The FEL and 3pt only share hydraulic fluid & pressure. All the components that use that pressure are discrete. Including cylinders and controls. What position did it stop i?. Will it move without any weight? How much? Does the relief valve make noise when you try to...

Does it shift and drive?

I have a Woods Landscape Rake with gauge wheels and the flip down grader blade. This is the heavily built one, and is solid quality. Only problem with it is so far I haven't found anything it will do well - but I bought it used for such a good deal I keep trying. l did loan it out to a guy...

A backhoe for everyday chores. You can always rent an excavator for the few times it is better.

In the workshop, I want to do a temporary plumbing bandage on a 1" brass cold water pipe. It's a pinhole seep right in the middle & drips about a drop every 2 minutes. No good way to drain it. My idea is to wind it with gorilla tape covered by some flashing & clamp that down with worm drive...

The 3pt piston O ring usually lasts until some water gets into the trans/hydraulic oil - often by leaving the tractor out in the rain. Judging from the pictures of that one for sale, it has had a rough life....I mean, just how in the world do you beat up the rear fenders? If a DPO can do that...

Your foot will put an imprint into wet soil that a roller can not erase.

Everything you mention could simply be that needs the hose renewed between the radiator and the overflow tank.

At this point you've soaked it pretty good. Now I'd try some heat. Not too much, just about spit-sizzle hot, and concentrate on the area surrounding the hinge pin - but not the hinge pin itself. A heat gun would be good for this. Then try to see if you can get any movement when it is heated...

If I was adding rear remotes I'd look at the JD power beyond kit instructions to see where they tap into the system. Then do the same with after market parts. Or just buy the kit. My guess on aftermarket parts is you are only going to save half, and the JD kit is surprisingly inexpensive (fo...

I remember when I first read that shop bulletin, it my first response was, "That is far too much detail. I already know how to do a compression test." Then I sat down and thought about it.... Glad you found it useful. rScotty

Here is a chart from the people who made the JD755 motor. This one is for a normally aspirated non-turbo Yanmar with a 23:1 compression ratio. The JD version is the same....maybe a little lower. 1.The "retainer" they speak of in the procedure can be made up out of an old injector using the...

Yes, electrically you can use any alternator/regulator pair that will physically fit. They all put out twelve volts. How much amperage (current) that they can potentially put out doesn't matter to the battery or the electricals in your tractor. The battery and electricals in your tractor will...

My guess is one or both bucket cylinders, too. They are in parallel, so if one is damaged they both won't work. I didn't understand, but am assuming that the lift arm cylinders are working? Harry's test is NOT one you want to do inside your clean shop or anywhere that an oily mess is going to...

I'm guessing that means that the Farmall A battery was negative (frame) ground. Just sayin' because not all old tractors are negative frame ground. And as I'm sure you know, the minimum number of conductors for any alternator is two, not one. In the GM the second "wire" is actually the...

Metric is simpler, but SAE is not very challenging. I'm not sure that we do ourselves any favors when we argue that the simplest path is the best one.

All you can do is ask. I don't see why not. In the past I always used independent mechanics - but good independent garage mechanics are rare today. To my surprise I found out there are now independent mechanics who do inspections instead of repairs. I found out about mechanical inspectors back...

I get a qualified inspection on everything mechanical that I buy - and that's in spite of ...or maybe because of... my being a lifelong mechanic. There are mechanics now who do nothing but pre-purchase inspections. Extended warranty insurors use them every day. For a reasonable fee you get a...

I'm the same way. There are too many stories running around on every subject and Social Media hasn't figured out how to deal with fantasy. Creating Documentation at least takes some time and effort to fabricate - without it I don't pay any attention at all.

I encourage you to be very particular about the test drive. Check everything. It should work like a new one with only that that many hours - which I'm not sure I believe given the tire and general wear - so be on your guard. Because if it really is that low hours then it should be fine...

Was that the infamous "quarter inching 3pt control"? The time period is correct, but I thought Kubota only put in on some of the B series: as in B7410, B7510, B7610, etc.

Kubota calls their six speed HST the HST Plus, or sometimes HST+. It comes with lots of features to customize the way the HST works. I like ours. It matches the 60 hp Kubota nicely. I'm sure the 3 speed works fine, but I just like more gears when i can get them.

I have no idea what that lever is. If it didn't do anything then it's best put it back where it was. And open up that needle valve under the front of the seat a half to a full turn. Then the arms will go down. From the sounds of things, the seal on the 3pt piston needs a new O ring. My guess...

I've never heard of anyone having problem mixing them. I've used several different brands of trans/hydaulic fluids in our Kubota with no problems. People do change types of oil, and there is no way to completely drain a tractor hydraulics system. A significant amount stays in hoses and...

You are welcome. Glad it worked.

Sorry right back. That looks like a suction leak to me. What say, arrow?

Great. It's fun to study something new. Please attach the documentation.

You are absolutely right. Better to wait. And something that puzzles me is Len says, "The connection where the tube from charge pump joins the filter housing". What puzzles me is the charge pump is not very accessible - most people don't even know it exists. It only services the HST, and...

That's wonderful. We sure covered a lot of ground. Would you have found it without removing "wheels,fenders,floor boards etc"? You should probably put "RESOLVED" onto the Thread title. BTW, What do you think was the cause of the leak? rScotty

Assuming that the OEM filter has more surface area of longer lasting filter media, it would be better to get the more expensive OEM filter and change it less often.

If you are going to use aftermarket instead of OEM filters, it makes sense to study up on how the different filters work in the system. I can't see any other way to tell whether the price difference makes sense. Or just use OEMs and don't worry about why they cost more.

I'm not sure either. But at least it is in the right system. What did you ever figure out on the Kioti clutch? Does it have one? If so, can it be locked or adjusted?

Those darn adapter plates.... they are each one a special case. Sometimes they require a special sleeve valve that screws into the 3pt casting right underneath one of the ports on the adapter plate. Frankly everyone of those plates was special and different. We are going to have to find a...

Not at all unusual for remotes to leak when they are activated. The problem is when they are activated one of the remote hoses holds pressure - but without a remote implement there is no pathway for fluid back to the sump. A leak there doesn't mean a problem. Try working the control lever for...

If you don't move the tractor, can you shift into and out of 4wd easily? If you can do that, it doesn't sound like a sticky mechanism. If using the loader to lift the front wheels off the ground makes it easy to shift OUT of 4wd then the 4wd is being stressed.

That could just be a sticky lever, or a sticky shifting collar in the transmission. It can also be caused by a 4wd with a mismatched front to rear tire ratio, although the OEM tires shouldn't do that.

Harry, ptsg,....on the one adapter plate that i worked on at the Yanmar dealer a long time ago there was nothing in the plate itself except two hose connections - on for power beyond and one for return, plus the mounting bolt holes, and some reliefs cut into the plate for O ring seals against...

Has it got a loader? If just a year old, is it still under warranty? What does the owner's manual say about leaving it in 4wd all the time? For that matter, how do you know it is in 4wd instead of 2wd?

I doubt if anyone can tell you whether or not to mix the fluids, since we don't have any idea what is really in either one. But I have had JD service managers I trust say you can mix low and regular viscosity HyGard. In fact, one called the JD tech dept. and asked as I stood there. SeaFoam is...

No idea on how to replace it, but several on how to make it better. While you have it apart is a chance to improve that poorly designed Yanmar fan guard. There's really no excuse for such poor design. Having made the mistake, I'm surprised that Yanmar doesn't provide an upgrade for free. If...

Working on our land is a hobby we both enjoy. From firewood to growing things to landscaping - it's all enjoyable work and good exercise as well. In fact, that hobby is why we got a few extra acres in the first place. We are older now, and having compact tractors has enabled us to enjoy...

My 80 series daily driver - bought new in 1997 - is still running just fine at 260,000 miles. I did do a head gasket at 180,000 and now one of the automatic door switches is failing. Remarkable power and traction for mountain winters, and the "smart" anti-skid braking system is the best I've...

Nope. Our Kubota HST has a tradtional clutch dry foot clutch. It also has a multiplate PTO clutch. You can look both up on Messicks. But lets not get sidetracked on Kubotas. I'd rather we stick to Len's problem. Right now it would help to see a parts book for the Len's Kioti so we can see if his...

I don't know about Len's CK 25 Kioti, but some HST tractors do have a traditional clutch. So it isn't impossible - his might have a clutch. I wouldn't have believed it either, but our M59 Kubota is a HST and it has a traditional clutch that looks like any other - left foot pedal and all. I...

Typically, a mechanic will want to check what the symptoms are and experience them himself. Then he will want to go over what you did and see if anything there has contributed to a problem. If he can't find something - and he may not - then the the next step is to get out your shop manual and...

Those diagrams are great. Did you ever replace that hose and clamps back on Feb. 1? Are you still trying to do this yourself or going to find some mechanical help?

I don't find ISO standards & certifications on common trans/hydraulic oils. In Europe, maybe.

What industry standards? The only industry standard I know of for trans/hydraulic oil only tracks viscosity and flash point. I don't believe there are industry standards for all the other things that are measured on motor oils for example.

Pretty much the same message I got from our JD backhoe from the same era. And yet when I used a thermometer on a string, it told me that the fluid temperature was normal. A lot of those senders are simply temperature-sensitive variable resistors of a sort where the resistance increases as the...

Is it possible to add an additional person to a private message conversation?

Maybe we can help. These things are always hard long distance. But here is an idea. It sounds like you are getting close. We need to know some information on that control valve. We hope that it is the type of control valve with a Power Beyond port - marked PB - and if so, we can use that port...

Just rebuild the solenoid and starter. The whole reason for having an old Yanmar is that they were originally built with the absolute top quality rebuildable components. They were designed to be fixed. You aren't going to be able to replace OEM Yanmar components with aftermarket parts that have...

I know this seems too simple, but the first thing to check if the fuel injector pump is below the level of the fuel filter, is to disconnect the fuel feed to the fuel injector pump. Fuel should run out freely until you turn off the lever on the fuel filter...and then start again when you open...

That's right. Tractors often have several hydraulic pumps for different systems, and each can be fed in a variety of ways. So it is entirely possible for a FEL/3pt to work just fine while a HST doesn't move the tractor at all. Power steering is a world all of its own. Even PTOs can be fully...

Good to see you back, and congratulations on finding such a nice tractor - it looks perfect. rScotty

Jack stands under the axle won't help any differently than having the tires on the floor. The axle stays put either way. The problem is that a tractor has a single center axle pivot right in the middle of the front. So as soon as you remove the last of the bolts that hold the bell housing, the...

I think that if you tell him the type of transmission or show a picture of a cutaway HST he he can figure out it out. It is just one swash plate hydraulic pump driving another. Lots of hydraulic systems are similar to that. Frankly, to me it didn't sound like an internal transmission problem...

What's it doing? Are you getting an overtemp code? We need to know what the tractor is doing with that switch info. Do you have an electrical schematic? It might show us if this is a simple or an analogue device/variable resistor.

This has to be something simple. I'm annoyed that we haven't found it. Wish you were local...do you have an old experienced diesel mechanic locally you can bribe to come and put an hour into it? rScotty

One thing I forgot to mention about my own first time tractor buying in post #68 above... is that looking back on our first tractor buying experience I was trying too hard to save and really should have bought a slightly larger tractor. Not very much larger and definitely not more HP, but the...

In that case I'd look first at Yanmar and then at Kubota... Those would go to the head of my list as we have had several of each and they are excellent. The Yanmar is first partly because it is farthest, and because Yanmar's attention to detail is so good it is nice to compare with. Then Kubota...

And that's another thing...those two dealers were probably locally owned and financed by a local bank. Now corporate ownership is more common. When that happens, a remote corporation makes the financial decisions that used to be made locally. Today's dealers are going to have trouble changing that.

Absolutely. One good answer that works for everyone is to buy low hour used equipment. Tractors that have been used enough to be proven, but not enough to be worn. I am old enough to remember another time - the 1950/60s - when new prices got totally out of reach. What happened back then was...

As you say and show, there's no reason to design the common throw out bearings so that they can't be lubed. That's just the way that most are. And I bet every mechanic out there has tried some sort of trick to lube an "unlubeable" throw out bearing. I know I have. I'll probably try it again...

Did you take the loader off or leave it on? One thing different from a clutch in a jeep is that the tractor has to have the front axle-to-frame space on both sides supported so that the whole engine won't suddenly rotate around the axle pivot when the two halves of the tractor are slid apart...

That is crazy looking wood grain.

We are all glad to help, I'm sure. Speaking for myself as a long time mechanic and repair shop owner I am still trying to figure out just how to make internet help effective. So help me too.... Just so you know, most dealers make quick estimates based on the cost for parts then double that to...

Needing cylinder seals and light bulbs every 15 years? ...well, shame on them. Maybe a jack a lantern is the answer. Or maybe not.

Glad it worked out, and doubly glad that you posted the resolution. Did you change the title of the thread to add "RESOLVED:"? How?

About 3 years ago we planted a three acre plot of very rocky soil with cover crop and grass. Not having a toothed implement that works well in rocky soil, we used the front end loader and a rock bucket dragged backwards. We already had the rock bucket, but I suspect a tooth bar on a regular...

I'll have to look in the original parts manual - I do have it as it came with the tractor. It's out in the barn somewere, Also the ops manual. I'll copy the page later today. As I remember, the 530 could be ordered with a variety of different front ends. I don't know if it it was offered with a...

Good Question... I don't know. I've never had a tractor with mid deck arms. Our old JD had a center mounted cultivator, but it used the accessory hydraulics and had its own control lever. No connection to the 3pt hydraulics at all. For the 3pt hydraulics, that needle valve is there and handy...

If you raise the 3pt up and then close the needle valve knob under the front of the seat it shouldn't move. If it still goes down, you may need to renew the seal in the 3pt piston. The workshop manual describes how to do that.

Yes, that sure doesn't look very utility to me. Tractordata.com is usually very accurate. I've never seen one with that narrow row-crop front end. It wouldn't work well in our mountainous country here. I think at the time tractors could be ordered with all kinds of options depending on where sold.

It's a JD model 530 utility. A 30 hp utility tractor with the factory wide front, small FEL loader, rear remotes, & power steering. Nice tractor. The telescoping lower arms were an option on a lot of tractors at the time, and maybe still are. I think they were standard on this model but we are...

Here's a photo on the JD lower draft link . I'm not going to take the implement off, but it is obvious how long the telescoping lower draft link is. The internal telescoping part is a solid 1.5" square bar that extends the length of that tube up to the weld down at the tip of the tape. Usable...

It wouldn't spook me a bit. I'll just stand off a ways and hold everyone's beers while you guys start 'er up.

That's interesting. I see what you mean by "flooded" now. No, I don't know off the top of my head whether Kubota is built that way or not. Or if they all are. But your explanation does explain why some of the early Kubota HSTs exploded diagrams seemed to show an extra relief valve where the...

Never heard of it. But I can see where it might work. Propane is denser than air but I wouldn't have thought enough denser that it would lift the carburetor float and close the float valve. ...and unless that float lifts, wouldn't extra propane continually spill out the overflow vent on the...

I don't know about all HST transmissions....or for that matter about the BX in particular. If anyone has a BX Work Shop Manual, it will be in there. But in general, HST transmissions could use their own separate enclosed "flooded" oil system...., but we could spot the ones that did pretty...

Good. It would have been poor form to cross-thread that opening at this stage in the game. I have found out since the other day that the old B7100HST tractors (vintage 1977-1984) used a HST charge filter in that same top of the HST case position that was a 10 um (0.0004") filter and mounted...

The other side of that is the shop owner's dilemma. Back when I had my repair shop, it was a rare customer who told us the whole truth about what happened with his machine. Women did sometimes, men almost never. That caused jobs to take longer and wasted a lot of our time. I finally came to...

You saved a ton of money and got a nice looking machine. The thing that really makes a backhoe into a multipurpose machine is a thumb. Even a simple mechanical thumb makes a big difference in handling tree trunks and root balls. rScotty

Uh oh... I probably shouldn't have done that..... Quick! Hit that undo button!

"Right to Repair" is primarily a movement by JD tractor owners to allow the tractor owner to access diagnostic software and needed technical specs for their own tractor. Deere doesn't want to allow that. Other manufacturers are watching .... and often following JD's lead. I think that is the...

WOW! WHAT A BEAUTY THAT IS ! LOOKS NEW !... and the price ...CONGRATULATIONS. I bet you could rig up a soft canvas cab and heater real easily for winter. In good weather I do prefer an open station with an insulated canopy like yours has.

You are welcome. I hope it helps someone. I was told to begin with the multipin connector and then look for abrasions in the wiring harness. Let us know if you find the problem.

Yes, he could. He has already tried jumping the tractor battery from a running car battery with no help..but, of course if the "frame end" of his negative battery cable is the problem, then jumping from a car battery directly to his tractor battery would not have helped.

To be sure to have spares on hand, you could buy two of the same tractor. Try to get them with matching keys.

There's no need to crawl under your tractor to trace that wire. To avoid the difficult gymnastics as your heal up, instead just move the far end of that negative (-) ground wire to somewhere convenient. Electrically, all of the engine block as well as the frame that the engine is bolted to...

Not a bad idea on the grease. I'll do that. What I did on mine is to put a vented plastic box around the engine computer in the engine compartment and then bolted a water and crud shield over that. In other words, instead of moving the computer into the cab for $2000, I built it a little cab of...

Sounds like you are on top of it. Most internally threaded tapered threads on Japanese castings are British Standard tapered thread and not NPT. And there is an interesting historical story behind that. But if there is an exception to most being British Standard, I would not be surprised to...

Yeah, you probably jumped the gun. But no harm done and everyone works differntly. Interestng about the breather oil puddle. If it ran good before and you tore it down for that breather oil then maybe back up to the compression test and put some thought into it . Here is a compression test...

How interesting... I also have a JD with that same engine and the same vintage. The 4.5 liter 276 cubic inch motor variation made from 2001 - 2007. Mine is in a JD310SG, but same powerplant. And I just fought with a weird temperature sensor problem for a year. I'd been measuring sensors...

Then it is sounding like the same basic casting was used in several versions but not finish-machined for yours - or maybe not for any BX23. So is yours maybe an oops or thin casting? Filters have two paths; Is it leaking from the center or outer? You might not be able to tell....but if the...

Sometimes it helps to know the actual rolling circumference on your tractor. To measure, put a blob of wet paint on the tire, and drive straight down a dry road in 2wd. Measure between paint marks. rScotty

Can you post the parts diagram. I cannot find that port on Messicks.com. There is a chance that it is just missing a plug or something similar like a hole tapped too deep. But when this happens it is almost always either a breather that is plugged. Another thing that happens is water got into...

Yes. Books help. A lot of times there will be a port somewhere for testing the pump pressure. Then finding out more about your hydraulic power is as easy as replacing a pipe plug with a 5000 psi glycerin-damped pressure gauge - about $20 at Ace Hardware. The gauge can stay installed permanently...

For all types of soldering, brazing, or welding, I enjoy the oxy/acetylene torch the most. It is so versatile and relaxing. It can add or subtract metal, join weird alloys together, heat treat, and stress relieve. What a marvelous tool. rScotty

Did you buy it from the dealer? Did it come with a problem? Hrs? History? BTW, what is the mechanical problem? Have you used the search function here on TBN?? There is a reasonable chance that someone else has had a similar problem with their NH. Also, without knowing rough location and use...

Might be. It looks like the spud is a machined plumbing part without exterior threads. So how does it mount into the block?? Is this is a type of adapter that is made to be driven into the block after the freeze plug was removed? And held by friction? Not sure I would want to do that to our...

Click, click, click.....and then it turned out I had to replace my Kubota battery cables after 7 years. The battery connectors had alway required twice yearly cleaning but were still good. The problem was the battery cables themselves. Fumes from the OEM wet cell battery had corroded the copper...

I use automotive coils interchangeably. A good one is good for decades. All that matters seems to be the voltage. Polarity doesn't matter to any coil I've used. My JD is 12 volt positive ground, so any 12 volt coil works. To test it I just lay a spark plug on the engine block, hook up the wires...

Just saw your old post. Yes, I heat my woodworking shop with that exact heater: a Rennai direct vent propane heater. In fact I also heat my machine shop with one, have one in the great room in our house, and two in our cabins!! Several are over 20 years old with no maintenance so far. All of...

The throwout bearing is inside the bell housing and sits between the clutch in the flywheel, and the transmission housing. Replacing it means splitting the tractor. When you are In gear and moving, a throw-out bearing just sits back away from the clutch a quarter inch and does nothing. When...

Agree. Metal stretches when it bends. It can't fit it back into the same place it was without accounting for the extra. Plus cut/weld/grind takes a lot less effort.

I think you are paying too much attention to the compression readings. They seem close enough to me. A compression test is not adiabatic. Compression readings depend a lot on how long you crank it and at what speed. If you can torque the head bolts to specs, then whether the bolts were stretched...

The L39 doesn't do regeneration. It was built before that was required. Where is the buzzer located? Does it sound like a warning buzzer or is it some part buzzing? Reason I ask is that the shuttle shift switch probably activates a relay that either does the GST shifting or triggers a solenoid...

Yes, confusing. My terminology is too vague. I'll elaborate. What I am referring to may be a USA only thing...and only in some areas. By "new gas" what I meant is specifically gasoline mixed with alcohol = ethanol. The alcohol attacks - dissolves - some of plastic and rubber parts in older...

I would love to hear that you actually went ahead and got one of those PS kit and how the power steering kit works out. Let us know. Might as well get the best one; they are all priced right - which is not surprising considering making PS kits versus the size of the market for adding PS on a 50...

That's a nice explanation.

Well.....not "they just gave it to me." It was part of the tractor buying negotiation at the dealer. Also included were shop manuals, tractor options, extended warranty, 50 & 200 hr service costs, trailering, financing, cash, and attachments. We batted things around until a deal was struck. The...

Back when we bought the M59, the dealer threw in one of these SSQA 3pt adapters for the FEL. I don't think either one of us knew of a use for it, but it looked well built & interesting. Over the years I've tried it with various reversible back blades to push and pull light snow....not very...

Yeah, you're right. Long distance failures are just frustrating to diagnose sometime. If we could be there it would take less time to test a few things than it takes to talk about it. I had the same frustration with our own mechanics back when i had a repair shop. So many mechanical problems...

I agree. You said the same thing as i did, but much more economically. BTW, we hired a drill rig to do holes for our pole barn. Best decision we could have made. They not only punched the holes in the right place, they set the poles.

Yes, it's possible and not too difficult. At the minimum it would take screwing together some commercially available gauges and parts. All pumps are rated at how much flow they put out at a certain pressure. More pressure, less flow rate. As pumps age, the max pressure they can create declines...

Why an 18" hole? The hp required for a post hole drill varies a lot on the way the auger is built. Soil is so completely different everywhere that all a person can do is relate their own experience. In clay, a lot depends on moisture and advancing the depth very slowly....sometimes with water...

We have discussed a suction air leak as being the most probable culprit several times in different posts since a week ago. We even discussed how it can happen as rubber connecting tubing ages. The tubing cannot be reclamped, it has to be replaced. Post #34 points to the exact spot. So are we...

Like you are doing, I'd be looking for some crud in the fuel tank first. plus checing that the fuel was wintergrade with a deicer. Also, check that the tank is venting properly. Easiest way to do that is just leave the filler cap ajar. If tightening it down causes fuel starvation then there you...

That's true, except for tractors with HST transmissions of course. And a couple of - not all of - the power shifts. Somehow I had gotten the idea that his Kioti was a hydrostat. If not, that's my mistake. rScotty

Good idea. For that to work you would have had to also plug the sump vent tube back by the 3pt. Otherwise the forced air does nothing. Even if this method works, it will only allow the pump to get fluid while the sump is pressurized. If pressure works, and then the pump quits when the pressure...

Eddie, thanks for mentioning the NH. I should have added the Ford/NH backhoe in with the JD310 and Case 580 before. They are all yellow, have the same price and features, and each one is as good as the other. They are incredibly ruggedly built, which means they age slowly. So a buyer can...

Sure, I've been right where you are. A little land, needs a cabin, mechanical ability and not much money. What i bet you will find is how handy it is to have one tractor to do chores and another for heavy work. I'm thinkiing you are already more than half way there... I have two buddies who...

I'm going to save that OP writeup in case I ever have to do that job. But the corrosion bothers me. Is that much water that common in fuel? I thought fuel was oily enough to prevent rust. I buy our fuel at a high volume gas station because I'm betting that passenger car diesel fuel is...

Nice flow diagram. In the center, the thing like a cup or shallow U is the symbol for the common sump. Right above it is the symbol for a filter, and notice it is 35 micron type. Then going on up are two pumps - the circles with a triangle inside. Somewhat higher and to the right is the HST...

Low Viscosity may sneak past some seals in hot weather, but only a little and should not be a problem. Regular Viscosity in cold weather is reluctant to be sucked into the hydraulic pump. Running dry can make the pump noisy and slow below zero F until the fluid warms up. If the HyGard seems...

According to the spec sheet, the T1030 NH has a standard hydraulic 3pt hitch. The specs show it to be just like any other compact tractor. . If so, it should also have a knob under the middle front of the seat. That knob normally works a needle valve that controls 3pt lift arm drop speed. But...

I've always wondered how loader manufacturers calculated "Breakout". It's a handy word, but is there really such a formal definition of "breakout"? I admit that your definition of lift at ground level is nice and simple. And it does avoid the problem of calculating curl about the pin. What...

Well, good on you for doing the diligence on the AI explanation - though in fairness that the mixup error you point out might just be a matter of poor AI grammar. Now I really am tempted to check the AI's math.... but I think I'll resist. We've already beat on this enough to know the right...

It's interesting that AI missed the same fundamental point. I'll assume everything that the AI says it right, although I didn't bother to check it's math. A compurter ought to know math. But none of the fancy AI explanation matters when it missed the basic point.

If it fires on starter fluid but chugs on fuel, that sure sounds like cylnders are not getting fuel at the proper time and sequence. Somehow the injector pump or injectors has gotten out of time. That's easy to check, and on an old style diesel there is almost nothing else it could be. rScotty

Are you sure your fuel has winter de-icer? Adding some extra won't hurt. Those symptoms sound like what happens when a fuel filter begins to clog up with wax and gel because the fuel is not winterized. That's just a guess, but it happened to me last year.

No, did you mean to call them hydraulic motors??? Or do you mean hydraulic pumps? Uh....Here we are ignoring that a hydraulic motor and are hydraulic pump are pretty much the same physically - one is turning a shaft in response to hydraulic flow and the other works exactly vice versa. It is...

The motor gradually dying is a typical symptom of a fuel filter that is pulling in gelled fuel - as the fuel filter becomes progressively plugged with wax and gel. Easiest to just replace the filter. Now is the time to add some serious anti-gel to the fuel tank. Having a bit too much anti-gel...

Thanks for the details. I'll not worry about it then. I haven't even looked at the accumulator that came with my Kubota kit... it came boxed from a dealer getting rid of old kit stock. Still in the box. I thought the kits were pre-charged. Maybe not. Even worse, I not only don't know where the...

Will the regulator on your inert gas tank allow gas to be delivered to the accumulator at say... 900 psi?

Yes, I agree with all those mechanic's techniques, arrow. They are all good to do. But I believe you are making the mistake of answering a different question than the OP asked. The OP's question was not whether air could get trapped in an open hydraulic system. Of course it can. We all know...

Nice test & writeup. I'm glad you tried it with the cap off and also without the thermostat. At this point I would leave the thermostat out. It isn't helping with the problem. Now I'm running out of ideas too. The problem is we don't really know for sure that coolant is circulating, and I have...

Oh, I see. Well, an accumulator would slightly resist the sudden vertical movement of the blower when the 3pt was dragging it on the ground, just like it resists the sudden movement of the 3pt arms. My guess is you would need to reset the accumulator pressure a lot higher to get much 3pt damping...

What's the status of recycling or re-refining used oil these days? There used to be lots of small town refineries that would take used motor oil, "re-refine" it, and sell it as off-brand inexpensive oil. I have no idea what process was used. Has anyone worked in that industry?

The FEL accumulator is a combination spring and damping system for the lift arms. Sometimes it is selectable on/off and also selectable rate Some tractors come with an accumulator OEM installed with names like "easy ride". We have that on our large JD. On others you can add it as a kit. Larger...

In your original post you said, " Over the years, I’ve hauled a lot of very heavy sections of trees from the site of a fallen tree to my log splitter. This is often been a trip of one to 2 miles on a gravel road. My assumption is that when cruising back to my place with a full load, every time...

Look. Let's back up & try to unconfuse things a bit. The problem is the OP has done a hydraulic oil and filter change and now his hydraulic pump is not moving fluid. So in his original question in the title of this thread the he asks, "Can the hydraulic system get air locked after a fluid...

I think that's a real good idea. Post hole drills are fine for post holes, where a little wandering and slant won't hurt. I've got one lashed to a tree where it has lived now for at least 30 years...Since we built the last corral. But if you are going to lay out a pole barn you may want...

I think too much weight is placed on easy parts availability. A good used LOW HOUR tractor from any of the major brands is unlikely to ever need any specialized parts... Ever.... Ask around. Read the forum. Tractors are very reliable. Sure you see people post about problems here on TBN, but...

Yep, anytime the cooling system is opened always run with the cap off until you are sure the air is purged. If there is air and a hot spot it will just burp it out and you add more coolant. That way you never have to wonder. What the history on all the radiator core replacements? What started...

Boy is that ever right. I said, "inside of a minute"...but that was describing a situation where there is some oil because it has been back-fed through the funnel. Even so, If it were mine, and didn't make pressure in a five or ten seconds I'd quit and find out why. Then prelube the pump through...

I would be real concerned about running a hydraulic pump dry for more than a few seconds. What I would do is the traditional mechancs prime: First of all, we know that a good hydraulic pump will self-prime quickly unless there is a suction air leak in the intake line. So that is almost...

Doesn't much matter. Often the sight gauge or dipstick for trans/hydraulic oil will have different level marks for hot or cold. If not, then it is probably meant to be read cold. That's because the level when hot is a guessing game based on on how hot the oil is and how much that heat has...

All that sounds good with the coolant lines. Some TLBs wth old fashioned EGR valves even run coolant into a shell around the muffler to cool the exhaust before recycling. There are lots of uses that benefit from coolant heat exchange. If you see no leaks, I don't see how those systems would be...

Well, it sure sounds like yours is one in which they tried to combine both functions. Having the pressure cap on the coolant storage/filler tank is diagnostic. Combining the functions wasn't real popular because the system can lose coolant over time without your being aware of it happening...

That makes sense. It sounds like yours is probably cooling via the bypass loop. As near as I can tell, the bypass cooling loop on Deere TLBs is there to prevent sudden overheating if the thermostat fails, and also to prevent surging of coolants having different temperatures. You could just take...

Maybe it comes down to how the equipment is treated. One construction guy I know always has new equipment breaking down, while another is still using equipment he bought - used - decades ago. I try to hire the second one. He's slower, but the work is better. rScotty

Well, I don't know the cause of your overheating. Was the head gasket leaking or not? But I chased "overheating warning" on our 2006 JD 310 for months before finding the cause and in the process of trying to dianose it myself found out a number of things. One thing I found is that the IR...

That says it all.

That's right. Digging is only half the problem. The other half is what to do with the dirt. Driving next to the ditch doesn't work very well.

Of course a mini excavator would be best, but if you can't afford the excavator, consider a compromise with a backhoe attachment for your tractor. Even a small backhoe attachment will outdo the stump bucket by leagues. Don't overlook the importance of a thumb, it is very useful for the lifting...

I think the last bad thermostat I tested was about 40 years ago. But I still do the test when looking for the cause of overheating. Most thermostats have the opening degrees stamped on the body. I use a regular kitchen candy thermometer - not an electronic - and a deep saucepan.

Ever wonder how many hours per year people put on their tractors? Ours are used mostly for small chores, snow, & landscaping - we don't do anymore mowing or field work. The newish Kubota's hour meter averages almost 100 hrs/year since 2008. The old one less than 50/year. It sure seems like more...

Well, it would do that I guess - though I've never tried it. A chain harrow pulled backwards would probably do as well or better. I think you are on the right track to borrow one and try it. I'm betting you will want one with the two gauge wheels, otherwise it stands little chance - but hey...

Since the LA504 has quick change connectors on hoses between the loader and the control valve, I would swap the positions of the bucket and lift cylinders. That would tell you if the problem is in the cylinders/hoses, or in the FEL control valve.

Our landscape rake with gauge wheels works sort of OK in a dry paddock, corral, or round pen - but not in a grass field. It really doesn't work at all for what you are describing. Sorry.... back to the pitchfork.. rScotty

Yepper. That tractor of yours sure sounds like what happens with wear and low compression. There's lots of tricks to get a diesel going when it is low on compression, but the real trick is in choosing one of the tricks that doesn't add engine damage to normal wear. It's definitely worth finding...

" You wrote, "fuel flow out of the filter seems fine when I disconnect the fuel line from the filter on the engine side." If you disconnected the fuel line, there is a chance that air got into the fuel line filter to the fuel pump. The symptoms sure sound like it. No idea why it didn't start...

Is there any way to compare based on quality rather than price?

I'm sticking with our older equipment for now. I understand it - and even though I am physically less and less able to fix it myself, take comfort in at least being able to understand and diagnose the problem. And the truth is that most old machinery is easily diagnosed and fixed. That's partly...

Just as a historical note, all of the 18hp and up Yanmars sold in the 1980s by dealers in the US had a shuttle plus power shift accomplished with hydraulic wet clutch/syncros between the gears in the gearbox. They did also have a standard dry flywheel clutch - but it was only used for initial...

Well, not much to add. You seem too have thought it through. I don't see why your solenoid to a priority valve wouldn't work. It certainly would not be crudely controlled, so my guess is you would just power it until what? a relief valve going off? Using a solenoid to turn on an adjustable...

Probably the easiest way to power a couple of additional two-way cylinders independently is to buy a standard two spool open center FEL control valve that has a Power Beyond (PB) port. Use its 4 workports to power your two cylinders. If you aren't using those extra cylinders, the flow just...

Sloshing? Where did that come from?

If you want to argue like that, take into account how technical writing differs from legal. In technical writing like tractor manuals, when something is not even mentioned that does not imply that it is included or excluded. What it means is that If fixed ballast is not mentioned, it is simply...

It's easy enough to just not use the stabilizers to elevate the tires if they are loaded. Then there's no problem. And it's probably more stable that way anyhow.
