Hello, The mower deck on my 455 will not turn off with the PTO switch. Turns on with no problem but when you push the switch back down it won't go off for some period of time. I have replaced the switch. Any direction would be appreciated.
still struggling after replacing control module. deck shut off and on properly a few times but then started acting up again. Started the mower with the deck engaged the other day. the deck shut off and now it wont come back on. any help would be appreciated.
I don't know about the 455 but on other John Deeres there is a seat switch that will shut down the PTO when it doesn't see contact. The seat switch is activated by the weight of the driver in the seat. When there is weight on the seat the switch closes to complete the PTO circuit and if not working correctly the circuit will stay open and not send power to the PTO switch.
This is the circuit description taken from TM1517.
To provide power to energize or de-energize the PTO
solenoid when desired by the operator.
The key switch must be in the run position, with the
brake pedal released (brake switch closed), the PTO
switch off, engine temperature normal (green area on
coolant temperature gauge), and the operator on the
seat to initially provide power to the PTO switch for PTO
My S.W.A.G. is the pto solenoid is sticking. A simple way to test the solenoid is to turn the pto switch on after the Operating Conditions are met. The pto dash light should be on. Turn the pto switch off and verify that the light goes out. The dash light and the solenoid are fed off the same switch contacts. If the light goes off and the mower does not disengage, the problem is the solenoid is not releasing.
