The motor on my sickle motor is constantly kicking out. It runs anywhere from maybe 5 to 15 seconds and then kicks out even if it's not cutting any grass.

The motor doesn't seem to be getting hot but the little circuit breaker does heat up and kicks out. I measured the amperage and it peaks at about 110 when I first started up and then slowly dropped off to the lowest I saw was 70 amps.

I turned everything over by hand and everything rotates quite easily. There's nothing that's binding up anywhere that I can find.
