BX won't pull a hill.

[dodge man]

I have a Kubota BX2350 that had devoloped a problem. It won't pull up a hill. I was mowing with it today, and everything seemed fine. I went up and down some hills, no problem. I have a fairly steep hill that I was trying to climb when the problem showed up. It acts like the rear wheels won't drive the tractor. I can see the front wheels spinning, but the rear ones aren't.

I tried it on some smaller hills, same thing. In 2 wheel drive it won't move, in 4 wheel drive, you can see the front wheels pull the tractor up the hill. Its actually worse in low range instead of high range. When it won't move, you can hear some HST whine, but nothing unusual. The hill I was trying this on is pretty small, and it would normally go up it easily in two wheel drive.

I checked the HST fluid level, and it was fine, it didn't seem hot or burnt looking.

This could be unrelated, but when I first noticed the problem, I pulled up to the garage and checked everything. I found the air cleaner badly plugged from a mouse nest. I cleaned it out and it didn't make any difference. I don't think this was related since I mowed some heavy grass earlier, and went up some hills and the tractor was fine. It doesn't seem like the tractor is lacking power, it just won't drive the rear wheels.

The BX has about 380 hours and I've serviced the HST fluid and filters according to the manual.

Any ideas? Thanks in advance.

In my opinion you have something broken inside after the hydro. and after the 2 speed transmission. As in Rear differential, because for the front wheels to turn your engine, hydro, and transmission must all work, but something is seriously wrong.. I am not a mechanic so take what I say with a grain, but lets see what other more experienced folks say. But this is what I think.

Yeah, I don't feel real good about it.

Hey not making fun but last year I thought I broke my BX too. It was only the brake was stuck on. It was a easy fix just had to adjust my brake.

I am hoping its something simple. I'm going to mess with it some today.

A HST that wont go uphill is not good

try going up the same hills when the tractor is still cold .. and then after its been worked for an hour or so and its nice and hot

It is not the hydro, because he says the front wheels are pulling the tractor up the hill, but the rear wheels are "dead" it is a broken shaft or gear or something like that in the rear end. If the hydro was the problem the front wheels would not have power either.

sorry my bad .. I thought it only happened up hills ..

so does the tractor move at all in 2WD when on level ground?
