Hi Matt,

Yep, thats what most of the other tractors in the 500kg/1100lbs category 
also used, but for a stock E20 I thought the 23x10.5x12 is large enough,
I may be wrong.

I read about the belt problems from others and made sure that they are 
tight. My belt still slipps a bit if I try to start from a stand still
in the D2 gear by quickly pushing down the accellerator all the way,
but I did not want to hurt any bearings by overtightening. During the
pull I had no problems of the belt slipping.

I did that in my second run. I didn't use the field weakening.

Yep, I felt pretty dumb when I had to push the tractor after the 
first pull due to the klixon cutting all power. It took about 2 
minutes for it to come back on. The motor was cold on the 
outside but I think the heat had not yet had time to propagate 
from the armature to the motor housing. So I have no idea how
hot the motor was on the inside. 

I wonder if the built in temperature switch would also protect
the armature or only the field windings. (or would the shunt 
windings be the same temperature as the armature and hence if 
the thermal breaker was attached to those protect the motor?)
