John and others,
The GE motors aren't labeled, but I'd assume they
have a temperature rating the same as industrial motors. Most industrial
motors are rated for a 40 deg C (72 deg F) temperature rise. Industrial
motors can frequently be much too hot to touch when heavily loaded.
I believe that tillers when performing
normal tilling are expected to move the power meter well into the yellow zone,
unlike the mower deck where you should stay in the green. I don't have a
tiller, but my snow blower manual specifically states that the power meter
should be in the yellow zone.
Hope this helps,
