F935 deck not engaging

[ycarl400]

Hi, I have a 2000 f935, the mower deck just quit after 30 minutes of mowing. The deck now just turns on for about 5 seconds and shuts off. The mower has about 2200 hrs on it now. The switch ohms out ok. Any help would be appreciated.

If it just suddenly stopped, I would suspect a bad safety switch. If it runs briefly, it is likely going to be difficult to figure out. This is because whatever is the issue requires a bit of heat to show up. This is not likely to happen with ohm testing.
Try testing for voltage through the switches. I would isolate each switch from the others in the circuit and run 12 volts through each and test continually for 30 seconds to 1 minute.

Low voltage allowing clutch to drop out, or pto clutch itself is failing
