Hi everyone,

I was checking my PTO on my 2009 5085M yesterday and it would disengage after about 10 seconds. Has anyone experienced before? I am thinking it has to be electrical (spool valve or solenoid of some sort), but I have no idea the location of the valve / solenoid.

Can someone point the way please?

Thanks,
Ernie

I would say you need a new PTO switch. You could also ask your dealer to warranty it since its defective if its still under warranty.

Thanks Ed. I'll give it a shot. Given how repeatable it is with respect to the duration prior to cutoff, it seems more of a thermal type event such as a solenoid overheating or something to that effect.

The switch is the lowest cost solution, and I guess I can climb up the money tree to the next costlier component if this does not fix it.

Are any error codes displayed. I'll guess faulty pto shaft speed sensor or loose wire.

No codes. The amber PTO light goes off on the dash at the same time I hear the click of it disengaging.

So I am kinda with you that something is telling the computer to cut it off.

Do you have a general location I can look for this sensor?

Thanks Jim

Ed...thanks for the feedback. I guess i was just grasping for straws.

I'll look for damaged cables in the morning and then move to the speed sensor. I have been looking for the location on the diagrams on JDParts for the sensor, but have not been to find it.

And pointers?

I think that's the pto sensor.
