Sudden start PTO Montana 5720

[lerauh]

My 5720 PTO has started to engage spontaneously when switch in off position. It may start and stop momentarily or run for several minutes. When PTO switch in on position stays on. Not sure if this a electric switch problem or problem with valve that actual engages PTO. Anybody have similar problem or better yet a solution?

Thanks, Larry

If you can locate the PTO solenoid, simply disconnect the wires from the coil. Run the tractor for a while and see what happens. If the problem goes away, you should ckeck your circuits for a stray 12v signal to the coil.

That or the switch itself.
