I just looked at an L4150, that the owner says is about a 1987 or 1988 model. The tractor has 1920 hours, (I assume it still works, and based on overall condition I think it is correct) but is quite faded and somewhat rough. It has set outside it's entire life, and his employees don't appear to have spent much time greasing it, as there is little grease residue on any zerks, etc.

Needless to say, there is some wear in the two main backhoe pivot pins, though they are still very usable. The tires are all about shot, and the rear ones are installed backwards for some reason. The FEL cutting edge is getting close to the needing replacement and the front of the bucket is bent down a little as he has it setup to use forks with it, but otherwise looks pretty good. One relatively minor issue is that the FEL brace bolts (the piece of metal with about 4 bolts at each end on both sides of tractor) have been a little loose for a long time, so the these holes appear to be elongated as the loader frame at the main arm pivot points shifts back and forth about a 1/2" as downward pressure is applied or the loader is lifted. I suspect that these holes are worn open and should probably be redrilled to a larger size and larger bolts installed. But even at idle it had plenty of hydraulic capacity to lift the front of the tractor off the ground.

The tractor started quite easily, even at 45 degrees, but smoked somewhat for a few minutes, but then cleared up. But it seemed to idle at a fairly high speed of about 1200 rpms after it warmed up a little even though the throttle was fully forward.

The backhoe has two buckets, and the larger 24" bucket was used a lot as the teeth are quite worn, but the smaller 12" bucket hasn't been used much. It would appear that the backhoe (which is a Kubota frame mounted unit) may also have a few loose bolts somewhere, as it shifted up and down a little on the back of the tractor as downward pressure was applied on the hoe arm, and then lifted again.

I forgot to get the model number of either the backhoe or the loader, but both are Kubota, and the 3-point arms have never been used (and are probably lost). The tractor does have the hydralic shuttle shift, which I understand is the preferred shuttle.

The backhoe has a large oil reservoir underneath the tractor, between the frame rails of the hoe. I don't think it has the auxilary oil pump though, as nothing is connected to the front of the engine crank. I assume the entire hydraulic system must run off of the tractor hydraulics?

It doesn't appear to have any signifcant oil leaks anywhere. One hoe swing cylinder should be rebuilt as it leaks a little at the seal, and appears to missing the dirt cover or something as the seal is recessed about 2" back from the outside edge of the cylinder.

The tractor is in Indiana, and the owner lives in FL, as he just retired after using it to build a nice subdivision. He had it listed along with a bunch of things I don't want, such as a bunch of sea walls, Lincoln welder/generator and a sea wall driver. The driver fits on the hoe after the bucket is removed, and the machine has extra hydralic connection hookups at the back that ran the driver.

Considering the overall condition I was thinking of offering him something like $6k-$7k for the unit. I doubt he will take that, but I guess you never know until you ask. Is it worth this much, or is it worth a lot more than this? Any thoughts on other things I should look for and what a starting offer should be would be appreciated.

I am just looking for something to use around my property, and won't use it that hard or that often. It could use quite a bit of work to get it up to snuff again, (fixing loose items, greasing things, etc) and a new paint job would make it look much better. I will need to check it over much more thourghly than I did with a quick cursory 5 minute examination if it sounds like he is willing to sell it in my price range.

Sorry for the long post.

Great Post !! I think for "5 minutes" of looking it over you saw a lot and you looked at the right things.

IMHO, the L4150 is one of the best tractors Kubota has produced. I've been a long-time fan of this chassis - Kubota refers to it as the L3. It was imported starting in the early '80's as the L3350, L3750 and L4150. In these years the model number was the approximate pto horsepower - so the L4150's 5-cylinder engine is more like 50 gross hp. Very smooth and trouble-free unit.

The really nice aspect of these tractors is they are strong and heavy. You've probably noticed the axles are more rugged than even the present MX5000 or M4900/M5700. The front axle would lift a house. (Double-shear king pins). The power steering cylinder is up on the side drag link, out of harm's way. Rears axle housings are massive.

If it has a Kubota loader it is maybe the LA950 - very strong and has a first-class valve. The original tires were Bridgestones I think - so they would be getting short after 1920 hours.

The light smoking on warmup is standard for these engines - nothing to worry about. About the high idle, check the solenoid idle control - it may not be dropping back when it should. (fuzzy memory here).

The earlier Kubota Orange faded easily - go over it with some "tire wet " and it will look brand new. If you get down and look up at the very bottom, it may still be shiny if it hasn't been parked in a swamp. Your observation that it doesn't leak is a good sign - but the build quality of these rigs was very high - even with hard use they hold up great.

If there is a separate hydraulic reservoir on the hoe, it probably has a pto pump at the back. This tractor has a huge oil capacity so if the hoe used the internal system there'd be no need for more reservoir. Another neat feature the L4150 has is a 2-speed pto - very handy if running a pump because at the higher speed you get full hydraulic flow with the engine loafing along at 1700 or so.

The loose bolts are a sign of a low-maintenance life. I would check the air filter (inner and outer elements). If they are missing or damaged it's not a great sign - but if they are present and whole, the engine is probably fine - even if the filters are dirty - as long as they are sound. The air filter has an indicator that moves a red band into view if the element is getting plugged.

About value, it could be worth a lot. Sometimes a L4150 with loader and hoe with 2000 hrs will still bring $15k. There aren't that many - and even fewer that are changing hands - so it's hard to tell. But for a 4wd TLB of that size, strength and power anything new is three times that.

Sorry for the long reply - but you asked about my favorite subject - L3's. In the '90s this series became the L4350, L4850 and L5450 (pic of my rig attached)

Take care, Dick B

Thanks Dick,

I really appreciate your detailed response. I couldn't see the PTO, with backhoe and everything being installed, so I didn't notice the pump. But it would make sense if it has a separate hydraulic reservoir. It would also make sense that it is running on high speed as I was surprised as the responsiveness of the hoe at the high idle speed. Also the fact that at this speed I could lift the back of the tractor in the air with the hoe arm, something that some compact John Deeres won't do even at full throttle (at least not the 40+ hp unit I tried).

I had a 1990 Case 580K that I sold last spring because it was too large for my needs, didn't have a demountable hoe (so I could use a 3-point) and I got an offer I couldn't refuse (sold for more than I paid for it). I was an extreme duty machine that weighed about 16,000 lbs, and designed for heavy construction work. I am sure Kubota parts aren't cheap, but you haven't seen expensive until you buy parts for industrial construction equipment. $8k-$9k just for a rebuilt transaxle, (not including any labor to install) not that I needed one, but it's something to consider when buying a used tractor. Add in the internal wet brakes that require the removal of the transaxle and each axle jsut to replace the brakes, at a cost of about $2500 and it quickly becomes obvious that unless you use a machine like this to for business purposes it is hard to justify owning one.

I may need to increase what I am willing to pay, but I figure it is a good starting point and will see what his reaction is.
