Re: (ET) Sickle mower motor constantly kicks out

10 amps is 360 watts being pulled or 1/2 hp just to spin the motor at idle?
That seems excessive. Another possibility is there is a short in the armature wiring (I assume the motor is a PM type on the sickle bar attachment or is it field)? If it's a shunt wound motor then maybe the field is open.

I checked the voltage of the circuit breaker while it was running and I got
.025 volts.  When I disconnect the secondary belt and just run the motor
with the center pulley free spinning it draws 10 amps.

Paul, I would suspect that circuit breaker. If you have a volt meter, take
a measurement across the two breaker terminals. I would guess you should
see a fraction of a volt. Higher voltage indicates above normal internal
resistance.

Hi all,

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.
