The speed control is held in position by the compression of a friction disk on the shaft. It is located on the drivers left side behind the edge of the black dash. A little tight to access, but possible without big disassembly. Suggest tightening slightly.
The PTO circuit has a relay. If the battery is low, the relay will not function. It is also wired thru multiple safety switches. Suggest checking wiring connections and functionality. Safety switches located under seat, brake pedal arm (under tunnel cover), speed control arm behind dash. Dirt at contacts, connection terminals or wiring breaks are common on these tractors.
