Electric cars have a few downsides.  One is battery weight - which is
an advantage for a tractor because the tractor gets extra traction.
In fact, most diesel and gasoline tractors have weight added.
Another issue is range - not a problem for a tractor because it rarely
travels very far away from the charging station.

This is Steve Heckeroth's Solar Electric Tractor model 12.  And we
even get a quick tour of the solar part!
