Both of those policies would tend to make me avoid that dealer. In my opinion both are signs of a beginner mechanic without much general experience. That is not a professional attitude at all - focused on money rather than the job. But I've got old fashioned values....now out of date....and...

It's worth a try. I once got one of my BH control valves with what seemed to be a "crud-in-the-relief-valve" problem to working right again by lifting the boom manually and then working the lever rapidly as it fell under gravity. On about the third try it started working normally and has...

Last year several of the Kubota M59 owners worked through a similar problem. Search on "M59 backhoe" & see if anything comes up. I'll do the same and see if I find it. Maybe smokeydog remembers... The short story is that we found out that any BH control valve assembly or even single replacement...

I like that idea!! Clever idea, and it ought to work. Switch hoses and see if you can get the boom to work while some other function - like bucket curl - becomes a problem. If so, then the problem is in the control valve not cylinder.

That's right. A spark happens when electricity has enough voltage to jump across a low-conductive gap. Static electricity has very high voltage. If If the plastic was conductive, current would just flow in the conductive material down to ground and no spark would happen. Be safe, rScotty

Control valve assemblies for backhoes are a lot more complicated than loader controls. BHs have check valves - which some loaders lack. And instead of just a single relief valve, it isn't unusual for BH controls to have a separate relief valve for each motion. These are common BH problem areas...

I'd probably go with one of the BX25 Kubotas. Nice little TLB with many options. They were made them from 2009 up until at least 2024 last I checked. That's an impressively long model run & they are known to be reliable. The B26 is the same only more so.... but more expensive. There are...

My Kubota did something similar with its boom cylinder... it began after a few years when it could not retract the boom cylinder enough to latch the boom lock. So...I agree with the previous opinions - the problem with yours could be either the joystick not sending pressurized fluid to the...

I was thinking the same thing. Sounds to me like the problem sounds more like an inept dealer than anything having to do with Korean tractors. BTW, the difference in loader lift is likely just advertising B.S. If the loader and the tractor weigh the same, they will perform so close to the same...

Interesting. I don't know what to say about that. You might want to check to make sure it is OEM hose. You said originally that it was compressing and restricting flow. But suction hoses are specifically made so that when new they can resist compression by the only forces that they will ever...

Of course you can. That $36 manual looks as good as any. But the best thing I have found helpful for this type of job is to share it with a buddy. Twice the fun.

Right, and the hoses get old and soft with age and hot oil...you need to replace suction hoses every so often. Sounds like yours is past due if it can be collapsed. It won't hurt to replace it.

Thanks tacticalT. The Kioti way of doing the gear and crack adjustable lifting links is a little different than the JD version, but both do the same thing. Instead of using a turnbuckle and locking nuts to adjust the lifting link length, there is a simple hand crank driving a worm drive gear...

Suction leaks don't show much leakage. Sometimes you can find them by looking at a suspected connection after the engine has been shut down overnight -then a suction air leak will show itself as a wetness at a joint as some of the trapped fluid works itself out. So if you have an oily hose...

This would be a good time to replace any "torque-to-yield" bolts with a better quality head bolt. Right, hold the FEL joystick on, and just run the starter without starting the engine. Be sure to put some safety struts around the lift cylinders if the tractor did not come with them. If working...

Stretch Head Bolts? What in the world are stretch head bolts??

Most tractors do better at pushing snow when they have chains on the tires.

I see. It makes sense now. A peculiar way to make a manifold.......You would think an intake manifold would be bulletproof. Anyway, it may be weird, but it worked once so can again. There should be a port to check the suction pressure at the intake and also prime the pump if necessary...

I agree with both of those ideas. Especially since you loosened the fitting on the steering pump ouput and got no flow out at all. Might as well hold off on the gauges until we find out if that steering pump is even turning. From what we know now, it may not be. If the coupling is, the pump is...

The common manifold problem is probably an air leak. Without gauges to test the output of the pump, we can only work on the suction to the pump.... and without gauges we don't know if we are getting anywhere. About all we can do is loosen a fitting and see if oil comes out. It will be slow...

Often when nothing works it is because the pump is not getting pure fluid. It has to suck the fluid from the sump, and if there is the slightest air leak in the hose from sump to filter to pump then the fluid gets frothy and nothing works right.. You might want to renew all those suction hose...

Like most older mechanics, I welded, brazed or soldered as required. If I was replacing a plastic radiator, it would be with one that could be repaired. Old copper and brass radiators are easy to repair, same for older soldered copper plumbing in the house. Anyone can do it.

B.S. Any halfway decent mechanic can do that job. It is simple. Don't fall for that line from an inadequate mechanic. This is basic wrench work. All it takes a wrench and socket set, some floor jacks, and a dolly. I had a repair shop. This is the type of job that you give to a kid just learning...

Is it nylon? How do you tell? Are there different types of Nylon?

Nice photo, Rocks91. That is a great picture of an old engine. Might be about the best textbook example of a worn out engine that I've ever seen. A classic. And you say it actually still ran? That's amazing... Even more amazing is that it still looks like it might be rebuildable - although it...

And there's the answer - a control valve made with a float function usually has a detent, but just adding a detent to hold a control in one position doesn't make float.

That's what I think as well - though I am not convinced that tank is nylon. It may be some sort of polypropylene - since that is a type of plastic popular for hot water systems. At a minimum you would want to find out exactly what type of plastic it is, and then probably look at making some...

Hydraulic fluid that has water in it becomes opaque - looks milky and foams. But if the fluid is transparent as it should be, then foaming is probably an air leak in the negative pressure - suction - line between the sump and the hydraulic pump. Hard to locate, so easiest fix is to replace the...

We built our place. Lots of TBNers have. It may be worth a search for a used yellow full size machine. Consider talking to a maintenance shop foreman directly. There are probably more nearby than you know. Small towns, schools districts, churches, local utilities, and shopping centers - any...

You are starting in on a big project. A home site involves a lot of digging, shooting ranges do too. And a half mile of gravel driveway is a huge project by itself. 50 acres is a lot of land. All these would go better if you start with a larger tractor. If you are able to handle normal machine...

That's exactly why I like a clutchable PTO. Best of all is a fully independent PTO that has a clutch for the drive wheels and another clutch just for the PTO. That is a common feature on ag tractors, but maybe not so much so on compacts.

It may be asking the impossible to get educational institutions to change on their own. Change may have to come from the needs of society. Back in the early 20th century a manufacturing society took the collision of pioneering "do it yourself" philosophy, in a country with more resources than...

Depending on what you are doing it might not matter. A live PTO -might or might not be clutched, and it also might/might not have an independent PTO clutch. A switched live PTO can put a large instantaneous load on the PTO. With a PTO clutch, the operator can keep the motor running and still...

HST wants for the tractor to be completely stopped to shift between ranges. The clutch doesn't seem to make any difference in range shifting. What did make a difference was extending the range shift lever a few inches. A clutch is handy for PTO engagement, and as a safety switch if the HST were...

I hope you are right. For one thing, the world may never see manufacturing like we had in the 1900 to 1960 years. Back then we had a surplus of skilled tradesman leaving their trades for manufacturing jobs. Today we don't have enough tradesman or jobs either - and both have long lead times...

I see nothing but benefit in learning a second or third trade or skill. Not only something to fall back on if the first one blows up, but it gives all sorts of opportunities to save money or just as a hobby. There just are not jobs anymore for a lot of college degrees. A single year learning...

I agree with Mike Rowe. Worldwide manufacturing competition is a math problem, and the answer is education. We did this before when sputnik went up - so I guess we can do it again. It does take time to see results because the kids that need to learn this stuff are in Jr. High right now. Back...

Most everything that is manufactured goes through the same cycle of being expensive and prone to breakdown at the first. That is part of the process. Whatever it is, after we make it for awhile we learn how to make it better and better. Until finally becoming common, inexpensive, and reliable...

Right. But doing that requires that the other side wants the same thing. That's a fantasy that is not going to happen. Somebody needs to have a real plan for how to get things done the best way with what we have.

I wish we had kept industry and manufacturing here, too. But we didn't. And now that we have given it away I doubt we can bring it back. For one thing, the countries who have the industry and manufacturing today fully understand that they now have the power that used to be ours, and have no...

I think it depends on the kind of after-processing. Most big diesels today use an after-treatment that injects fluid into the exhaust stream. They idle just fine.

I hadn't thought of a wedge - though I've used the same leverage to take other things apart. I'll remember that one. Sometimes it's worth looking into the parts book to see how things are put together before forcing them. There isn't much but the bearing circlips holding any PTO shaft in place.

Or just put a smaller gas motor in it. I don't know Fords, but they probably make a nice six that will bolt right in. Our old Chevy dump truck has a small 6 cylinder gasser. It gets around just fine in the mountains with a split-shifting manual. Not fast, but inexpensive and reliable. rScotty

Check your personal messages.

The other side of that coin is the only way to make something better is to dive in and make it - with the eventual goal of making it work better. That's what mech-heads do. I don't like being forced by the gov't.. but that is what govenments do. And while I don't like being forced from my...

There has been quite a bit written about irratic swing problems in backhoes. In Kubotas it seems to be a relief valve or check valve problem in the backhoe control valve assembly more often than not. Nobody seems to know for sure, but some believe the proble is a piece of crud gets caught on the...

I had a tire with a slow leak that developed cracks & was concerned that the cracks might fill up with dirt and rocks and abrade the tire. The tire on the other side without a slow leak hasn't developed any cracks at all. So I filled the cracks in the tire using a plastic spatula and Dow...

It's fascinating how many ways there are to do something.... just how much work people will gamble against how much risk they are willing to take. Chaining it to a tree and driving forward will probably accomplish something, but you don't have any control over what that might be. It might even...

Makes sense. most "starter issues" are really battery issues. Followed by battery cable ends - that's all 4 ends, then solenoids, then the key switch that activates the solenoid, and if all those fail it might be the starter itself...but rarely is. The starter is the last thing on the list...

That was my conclusion too.

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...
