Trying to help a friend with his Kubota Zturn mower with PTO not engaging. Any one have a trouble shooting guide or a PTO circuit diagram to share. Any help would be greatly appreciated. Thank you in advance

is the belt intact? If so, does the clutch get +12v and ground at the connector? If not, find out why (relay, wiring, etc). If so, the electromagnetic clutch is bad.

if no 12v at the clutch, check fuses. all good? take the front panel off, sits where your heels are. Behind that panel is 4 relays. Swap them around and see if another function doesn't work, like won't start or something....if that's the case, you h ave one bad relay. I had to put a bunch of them in at the shop.

Thank you for the information I will do some checking this morning and get back with an update
I have found one bad relay that had the kill wire grounded and killed the spark as the engine cranked. Replace it and engine started thinking all is well not so now PTO will not engage we shall continue

Update
Thank you Lugbolt
By changing relays around ( 4 of them) I found 2 bad relays one in the start circuit and one in the PTO circuit
