If the tractor doesn't move in the higher speeds, the field weakening
resistors might be broken. Or it could be a stuck relay. If the current
but the tractor goes faster that's kind of life. Weakening the field
increases the current draw a lot for more speed.
As for the charger, there are other people better equipped to answer this
one. Bill Gunn has the parts.
Or you could go solar.
