Ah hah. Now we're getting somewhere.

What's happening is this: There are three resistors in the front of the 
tractor to control speeds 1-3. As you push down on the throttle, the 
little switches in there are supposed to close the contactors 1A,2A,3A 
which bypass the resistors. As the resistors are bypassed, the speed 
goes up.

You're running around in speed 1. Not much fun.

Now for the big question: Why is power not getting to 1A et al.

Let me check my manual.

It's the gauge on the right. THe left one is voltage.
