Interesting way they rigged the limiter chains to control the height of the lift arms. Hooked directly to the arms in place of the limit chains from the PTO output cover area.
The lift arm adjustment on the right lift arm appears to be a real turnbuckle instead of the Ford gearbox. The other side is unusual, too but I can't see details.
If you get that tractor running with even non-original parts, it will be a real conversation piece!
