Between a new gas engine, 4 wheel motors, a variable volume pump, adapters, hoses and such, I see 7-8 thousand in repairs in my head, plus the cost of the machine, makes $10K.

Don't know if it's a quick attach or pin-on system. If it's pin-on, there's another $1500-$2K to convert to QA.

Again, those are all severe guesstimates in my head coming in around $12K when it's all said and done. Plus transportation and no value on your time.

Price included two mowers, broom (sounds like a conversion), bucket, forks. There's several thousand in value there. And you could repurpose the Kubota engine that's in it for something, I'm sure, or sell it.

You can get a new PT425 for $16K. But no implements.

You'd have to be project oriented and love to do that kind of work.

Are you thinking of buying this?
How mechanically inclined are you?
If you are even a little handy mechanically and have the time pressure test the Hydraulics if you can. It is likely a pretty simple gauge and length of hose and 1 or 2 fittings will give you most of the info you need to know. Just need to find where to hook into system and what the pressures are supposed to be.
IMO Paying 2.5K for a something that has a replacement value of 30k is worth some time investigating .
Just some random thoughts now.
This is really rare but if the "transmission side is junk" or other wise not working. Yet everything else is working it could be something as simple as a collapsed hose....or a deteriorated hose/bit of dirt foreign material blocking a valve/oil flow. Checking pressures will help sort that out.
Is there a hydraulic filter on it? Can you remove it ,cut it open and have a look inside?
Shop around for replacement pumps and drive motors if needed. Don't be scared to look overseas either. I have saved some serious money [over 60% recently] being patient and waiting for 2-4 weeks for parts to be delivered. Before you buy you will want to know as much as possible cost wise
There thats my .25c worth good luck if you buy it

It doesn't have a transmission. It has a variable volume pump that is directly driven by the engine. That pump drives the 4 wheel motors forward and reverse.

Pumps. Hoses. Dated machine. Fun project but not cheap and end results probably not worth it.

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

 

[SpringHollow]

I do not see how that modification would affect the pump. It will affect turning radius, lift capacity, and load on the wheel motors. I suppose indirectly it could, increased wear on the front wheel motors could create debris that then enters the pump.

 

[marrt]

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

Please expand on how changing the wheel base is going to effect the hydraulics one way or another. Beyond a little extra drag/load from not tracking the same as before having a change of centre pivot is all but irrelevant to the hydraulics

I think there would be a lot of added drag on several places on the machine if the wheels weren't the same distance from the pivot point.

First, you'd have a skid steer effect. Added side loads to the wheel motors.

Second, I'd think you'd put more stresses on the steering cylinders and their mounts. That would require more hydraulic pressure to push the rams as well.

Third, I'd think the same of the center mount points.

lol skid steer effect. If that were the case it would steer like a skid steer and not like an articulated machine. Any "skidding" would be eliminated by valving of one kind or another. No doubt the machine came with the valving in place
Like I said in my first response to the OP IMO if he is both allowed and is willing to do some investigation into the "transmission side" [sellers words NOT mine] it is worth the time for a 2,500 dollar price tag on a machine he claims has a replacement value of up to 30K

 

[ponytug]

These machines have a series of three pumps (drive, PTO, & aux), and while the drive pump intake is filtered, the rest is not, and in particular the drive motor drain lines dump into the general hydraulic tank. So, if, as the seller indicates, that the main drive pump and motors are shot, I would expect damage to the remainder of the hydraulic systems; PTO, steering and cylinders. I don't understand why the seller says it will need a new gas engine, unless the engine runs, but is impaired in some way.

As @MossRoad indicates, I think that the buyer might just be getting a tractor frame, diesel engine(?), and perhaps attachments.

When hydraulic pumps or motors disintegrate, debris has a tendency to go everywhere.

Even if it was purchased just for the implements, I would think it worth the while to disassemble the cylinders to inspect for debris.

It is probably just my limited mechanical skills, but I am having trouble seeing much of an upside on this one.

All the best,

Peter

Why is the link showing up in (what I assume) in Chinese script?
Has TBN been hacked?

No, see post #3 above. Apparently it is a known ISO character interpretation issue.

There's no valving in the drive train on these machines. None.

Imagine the rear wheels were moved 1 mile to the rear. The front wheels would barely move, verses the rear wheels, when making a hard turn. However, the front and rear wheel motors on PT's smaller tractors are directly connected on each side...e.g., the output from the left rear motor is the input for the left front motor. So, hydraulic fluid MUST go through the front wheel motor at the same rough rate as the rear motor, even though the front motor couldn't turn much in this scenario. Obviously, this wouldn't work well for long.

Also, Peter's comment is spot on. The wheel motor circuit is NOT directly filtered on a PT (or most other small hydraulic equipment). Therefore, a catastrophic failure really is catastrophic. On big machines, it's necessary to pull a cleaning device through all the lines after a catastrophic failure...in additional to disassembling and cleaning every motor and pump in the circuit (along with the hydraulic reservoir and fluid of course). Even then, you're not going to get everything and one can expect reduced service life for each component going forward. Fortunately, it's rare to have this sort of failure. The more usual case is gradual deterioration due to normal wear or contamination.

 

[SpringHollow]

The weak point is usually the ground contact of the tire against the ground similar to a 4WD truck. Wheels slip as needed when the vehicle turns. Then it is just a mattter of whether the components are designed to handle the forces prior to wheel slippage.
