I just purchased a massey 135 and I believe there is something wrong with the 3 pt hitch. The tractor does not have any remotes. The position lever does not have any response on the lift moving up and down. The only way the lift will move up is if I move the draft control to the highest position and if you move the draft control down any the lift falls. It seems like the position lever moves more freely than it should. Could it be that the position lever is stuck in the highest position? Is there something on the lever itself that could have broke? Thanks
