I had problems with the tractor drifting when it was in neutral. I found that the adjustment cam eccentric was worn in several places so I replaced the cam and the plate that it travels in. I jacked it up after installing the new parts and set the neutral position and the problem was solved. The only issue I have now is that shifting forward on the hand lever is difficult. If I loosen the nut and washer on the plate it will shift easier but then of course the hand lever will slowly slip down slowing the speed. I looked at it last night and when shifting the cam seems to drag hard on one side of the shifting plate. Is there something in the tranny shifting assembly that requires being greased? I don't think that greasing the plate and cam will do anything as it will probably wear away quickly. Anyone have any insight?
