Question about Oregon Scientific Electric PTO Clutch for Cub Cadet, MTD and Warner
I've had the same problem. Intermittent shut-off of the pto. Found out that the pto (electric clutch) draws heavily on the battery current to stay engaged.Clutch is actually an electro-magnet. I bought a new battery (300 cca) the bigger the better and clutch now works fine. Old battery was still strong enough to start engine but not strong enough to engage pto. Old battery was 4 yrs old. A good clutch will click if jumper wires from the battery to clutch wiring harness are connected (with out motor running.)

Got the same problem. It's maddening. It's not the PTO switch. I just replaced that for $40.00 on the dealers suggestion. It seems to be either the clutch itself or the electrical harness connecting the clutch to the electrical system.
today it quit again. I just tapped on the clutch about 20 times with the handle of a large screw driver and low and behold when I started it up, it took off again. then quit momentarily. then took off again. I was able to almost finish my 3/4 acre going very slowly.
for sure there is something wrong with the clutch.
