- John Deere 2032R & X350
My John Deere 2032R (although it could easily be a generic problem) Rear PTO engages normally, then disengages about 20-30 seconds later. The PTO light stays illuminated. The PTO will not reengage unless the engine is shut down and then re-started. I have the tech manual, but there is no description of the phenomenon that I can find. It seems clear that there is some electrical interconnect issue at fault.
One of the curious aspects is that the PTO runs for 20-30 seconds, never more than 40 seconds. If there were an electrical interconnect open, wouldn't it either fail to engage, or disengage instantly?
Similarly, it does not seem likely that it would be a fuse or loose connection because the PTO can be re-engaged after the engine has been re-started.
The tech manual "PTO Circuit Operation" doesn't seem to have any clues that would explain the PTO running, then disengaging and then after the engine is shut down and restarted, engaging normally (then disengaging). Rinse, lather, repeat.
Is there some pressure-related sensor that might open the circuit, such that if the hydraulic pressure were too high or too low, it would open the circuit to the PTO solenoid? Just guessing here at the risk of leading helpful troubleshooters down the wrong path.
