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.
