Huber Won't move

JTWAT · 2025-10-11T01:35:00.000Z

I have a Huber M-850-A that won't move forward or reverse. It has hydro static drive. When I move the lever forward or reverse, I can hear it whine and start to move but stops. I have changed all the filters and fluid but no change.

Thanks. I'll probably just order one from them with the parts order I'm placing. $65 is pretty reasonable.

Huber Maintainer in Wisconsin. I think you posted their number in one of these threads. Have you bought from them?

I spoke with Jerry there. He is sending me the manuals for my 850A.

Does anyone know the capacity of the hydrostatic transmission ATF tank on a M-800?

Hi @Decae ! Welcome to the Heavy Equipment Forums. I'm not familiar with the M-800, so I would suggest contacting Huber Maintainer and ordering maintenance and operators manuals for your machine. It may be similar, but likely not the same as my M-850-A:
