My JD1025R won't start. Fuel solenoid is working but no action on starter. The battery has been checked. However the dash indicator says PTO is engaged. In that position it will not start. Although the yellow switch is down no go. Checked all relays, fuses, etc. Wondering if the engine controller is faulty or switch faulty. Still scratching my head on what to do next. Anyone have this problem. Tractor is 3 years old.
