I have a Poulan Pro mower. The blade will engage on initial startup, but after running for about 2 minutes it disengages, and will not engage again.
The knob (for engaging the blade) is working, because while it is pulled out (to engage), I cannot go in reverse or get off the mower.
Nothing happens on the deck though. Nothing spins...I've cleaned out all the connections, but so far nothing has worked. Hope someone can help. Thanks!
It is an electric PTO and needs a good 12V to stay engaged
So the first thought is bad battery or bad alternator.
The PTO is a big solenoid and generates a lot of heat, the hotter it gets the more power it needs.
They need to be cleaned , blown out with air from time to time.
The wires can get a bit chewed up which again will cause overheating and some have an adjustable air gap which needs to be adjusted from time to time
