    Jack up the machine where the rear wheels are off the ground and start it and run the wheels for a few minutes should get any air out.

    Lopper apreciates the reply to my first post. I've yet to run it but had ryder jacked up and the response from the joystick was still sluggish. Mower is 10 years old, zu201 4k, and has 850 hours on it. (low). How is the air released when up, do you belive my hydros need attention after tweaking cable settings and have you ever bled your hydros. :cool:

    With no load on the wheels I guess the air bubbles just float up out of the fluid. I guess with no load on the wheels it just speeds up the process. Another thing you may want to check is the hydro belt and see if its tight. If its loose then it would cause what your describing.
