I am just getting started fixing up this tractor - I already replaced the transmission drive belts and pulley. It was moving slower forward than in reverse, so I adjusted the pedal. Now the problem is worse. My question is, Should there be some limit on the rotation of the control lever on the hydro unit (Sundstrand)? I can rotate it so it points upward. Also, I can pull it out sideways until it hits the frame of the tractor. I am wondering if this is evidence that the internal pin is broken (as was touched on in another post)? Thanks!
