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.

dl, I won't have access to the 455 manuals until tomorrow. I'm sure there is a serial number break for that model. Could you post your serial? Or send it to me in a PM.

the sticker is damaged, but it would be in the early range. I purchased used, but I believe it is a 93 model

DL, The part number of the control module is AM136681. It retails for $106.05. Let me know what you come up with.

Hi Guys, First Time poster here.

DL,

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.

Just a thought !:unknown:

Thats actually a pretty complex circuit including a time delay. Seat switch, reverse pedal ( I think that one has RIO), etc.

I would unhook the wire from the PTO and hook it up to a meter or test light. See if it ELECTRICALLY works first.

It could be hanging up from a mechanical standpoint so you need to rule the mechanical part out.


As mentioned the seat switch could be an issue but should kill the motor too. Make sure your reverse switch is not messing you up.

This is the circuit description taken from TM1517.

Function:
To provide power to energize or de-energize the PTO
solenoid when desired by the operator.

Operating Conditions:
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
solenoid operation

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.

Well that is my guess,

GotDeeres
