they just lost most of their power. The piece of equipment is a mini skid steer made by Gravely, same design as a Kanga. Each front wheel has it's own motor which turns the rear wheels by a chain. It was working fine and then all of a sudden the front wheels have lost 3/4 of their power. It will move but hard to get it on a trailer.
Just put a new hydaulic pump in last month, changed both hydraulic filters, checked the solenoid valve that lets you operate the controls, new spark plugs, air filter, fuel filter. My hydraulic guy thinks it's the wheel motors but I can't turn them with pressure on the system, which I assume is good.

Anyone have knowledge concerning hydraulics like this. I don't think it's an electrical problem but who knows.

By the way, Gravely doesn't make the unit anymore so finding parts is a nightmare.
Help, help!!

Sounds like the wheel motors. We had two go on us last year and they did the same thing. Have fun changing them, they're a bear (we have the Finn).

Yea, it doesn't look like changing them is gonna be fun.
