My lift has been fixed! I removed the MLS valve and replaced all the seals. Now the lift arms stay up after the tractor engine has been shut off. Thanks for all the suggestions!
My Bobcat CT225 3 point hitch leaks down after the engine is cut off and the rear lift is jerky. It leaks down with the speed knob fully closed. I just purchased the tractor so I don't know its history except it was mainly used to mow with using a rotary mower. Thanks for any ideas.
