I just bought this tractor yesterday. It needs some TLC for sure. The Draft Control and Position Control were both working somewhat. I then removed the quadrants to straighten them. When I put them back together, the position control doesn't work and the draft control will raise and lower the implement but trying to get it to hold to a steady position is next to impossible. If I understand the operation of these controls, that is normal for the draft control. Any ideas on how to get the position control working?
