Drove it up and hook up a piece equipment. Got back on started to move only move a foot or two it stop lost all Hydraulics. No power take off, 3-point lift steering and transmission. I was wondering if you think it the torque limiter or the hydraulic pumps?

Thank you for any help.

In my mind it could be the hydraulic pump drive coupler. Not to disagree with any one
It could be torque limiter or pump coupler. I would think torque limiter would give some sign of trouble. Itll be interesting to find out

For 1000% percent accuracy, remove the 3 pt top link anchor. Remove the frost plug behind it. Start the engine. If the shaft doesn't turn it's the torque limiter.
