MF 135 3pt Hitch problems

Most 135s wern't built with pressure control and not to confuse you that's a weight transfer system that needs a special hitch. The old massey dealer in my hometown explained it to me as draft control for pull type implements.

My tractor has it, but I've never used it - you have to modify implements eg strenghten the tounge to make it work correctly.

To use position control, the draft lever has to be at the top. And to use draft control it works best with the position control at the top

Draft control is only good for a plow or other ground engaging immplement. It lets the hyraulics adjust the depth so the implement pulls the same all the time. So in sticky dirt it doesn't plow as deep. Sometimes that's not what you want. Then you go to position control to set the depth and shift down when the going gets tougher.

Position control on the 135 should allow setting the implement at any desired position between in the ground and fully raised and it should stay there with the pump running. It won't stay there forever with the pump not running because a used pump and cylinder leak. The controls operate at the pump determining its output, I recall by controlling how long the intake valves are closed.

And draft control should allow any amount of drag including none at all.

Both controls are active over nearly all their range an produce an implement height or drag proportional to their position. They are continuousy variable.
