The mower is a scag turf tiger, 1000 hrs on it, Kawasaki 29.0 FR791D motor.
Cutting deck shutdown during mowing. Mower will run and everything else seems to be fine. Here is what I have done to diagnosis problem.
1. Removed PTO switch and checked its function with circuit tester, OK
2. Put a jumper to the PTO clutch at its harness, it closes OK.
3. Tested 20 amp fuse to PTO, OK
4. Tested cable from PTO switch to deck switch, OK
5. I did find a frayed powder cable from battery connection to PTO switch, replaced, made no difference.
Not sure what to check next. Don't have a manual so I don't know if there is any other fuses somewhere. Concerned that maybe the frayed cable fried something in the PCM computer, but see no evidence of arcing or other overheating on any wires or modules.
Thanks,
Bill
