The PTO switch works and will kill the engine if nobody is sitting on the seat but the deck never engages. It doesn't even seem as though it is trying to engage. Does anyone have any ideas for me? I tried searching and was unable to find an answer. Thanks in advance. [Reply]   [No Email]

I did end up finding a disconnected wire up near the front of the engine. Once that was reconnected, everything worked again.   [Reply]  [No Email]

If you do, the clutch could be bad, the air gap needs to be adjusted, or a bad ground at the clutch. Since you said it stopped while mowing, I would lean toward the air gap needing to be adjusted. When the mower cools down, will the pto clutch reengage? If so, that is also an indicator of the clutch air gap being too wide.   [Reply]  [No Email]

It has a ground terminal on the ignition switch and wasn't getting a good enough ground. Ran one from where neg cable bolts to frame and it has been working good ever since.   [Reply]  [No Email]

Open wiring or possibly open winding in the coil of the clutch. With the engine off, can you take a jumper wire and get the clutch to click? Or get a multimeter and check for continuity thru the clutch winding. Bryce :)   [Reply]  [No Email]
