Kubota b2150 HST not working

[Matoyan]

Hi all. I could really use some help with this one. This is a new to me tractor that I can’t figure out. The tractor moves in low forward and reverse but at full throttle, barely moves in medium even at full throttle, but does not move at all at high. I’ve changed the fluid with proper kubota hydraulic stuff, changed the hydraulic filter and cleaned the screen (clean with no metal particles). When pressing on the foot pedal, it does sound like maybe there’s enough pressure or maybe the relief valve is opening. I would post a video but I don’t know how.

Post video somewhere like you tube and link it here (this site doesn’t support video)

I'm going to say you have a bad clutch, it's not transmitting power to the HST.
Really easy to find out if this is the problem, engage the PTO it should spin, put the tractor in high then try and move the tractor, the PTO should stop spinning.

It’s a brand new clutch installed by the dealer few weeks ago. But I’ll try that.

If the pto stops spinning, is that good or bad?

I’ll post better video tomorrow now that I know how to do it.

That's good because then it's the clutch that's fried and not the HST.

You can also look down here at the HST input shaft, it will stop spinning or spin very slow when the clutch disk / pressure plate is bad.

Then you may need to get the dealer involved again??

The clutch may need to be adjusted if it is really a new clutch in the tractor.

Is it acting the exact same as before the clutch was replaced?

When I bought the tractor, it had a blown out clutch and a hydraulic leak where the shaft goes into the transmission. The previous owner said “nothing wrong except for the clutch and the leak”. Thinking back, I know when we tried to load it on the trailer, he only ran it on low and it didn’t seem to have any power to go up the ramps. I just thought it was because of the bad clutch, now I’m thinking maybe he lied.
