I have a Skag model STT61A 29 DFI SS. While mowing the blades stopped cutting. I check the PTO switch and fuses all are good. All my connections are good. I have no power to the clutch. the engine runs fine. Any ideas???? Thanks Harold It has 888 hours on it.

Trace back up PTO wire harness for pinched or broken wire.

I checked the wires and all are good, I am going to take the PTO switch to another dealer to check it out.

In the manuals section of the Scag website you can download the manual for your machine. You will need your machine model and serial numbers to get the correct manual.
At the end of the parts section are the wiring diagrams that are engine option specific.
Depending on your electrical skill level, you may be able to trace and check the wiring to find your problem.
Bear in mind that there are several safety circuits and the electronic control module that prevent the operator from inadvertent operation.
Check the electrical system grounds as they all terminate on one of the engine mounting bolts and the clutch ground is connected there.

Due respect...opens (broken conductors ) are often hidden behind perfect appearing insulation. Ohm meter or test light and wiggle wire around while watching instrument. Also upstream to ? sw...12V present etc...?

I took the PTO switch to another Skag dealer and the switch was bad. The first dealer said the switch was good and bring it in for repair to check wiring. I brought a new switch from the dealer that said it was bad. Hooked up and it running perfect. Thanks everyone for your input. Harold

I think you know which dealer to stay away from.
