SOURCE: electric pto will not engage

had a similar problem. The engine mount bolt that grounded the PTO black ground wire was loose- causing the pto to work erratically. To see this bolt (13mm i think) you will have to lie on your back and look under the machine. It is above the front steering arm of the right tire. If the wire is dangling you will need a new bolt. Thanks for the previous posts ;)

I see this problem not as an electrical but a seize problem. Since I can't be there to inspect I am relying on your discription of the problem. I would go first to the place of the problem. If this solenoid goes up to disengage and down to engage ,or the opposite, this is most likely your problem area. It may be seized in the disengaged position therefore not allowing the blades to get spinning. Disconnect the belt and try to turn unit by hand, if tight or completely stuck use penetrating oil on pulley shaft.If shaft loosens up and blades engage this was the problem. Is there a grease fitting anywhere in the area?I hope this at least gets you started in the right direction. GOOD LUCK.
