Nonsense. The insulation is there so the wires don't short out against each other, the tractor's frame, etc. Current is not 'lost as it is passed down the line' with or without insulation. The current in a circuit for a given voltage depends on the resistance of the circuit, which is not affected by the insulation on the wiring.

I beg to differ. I do remember covering this in my Advanced Calculus III class as isothermal conductivity, looking at the gradient and using the del operator to calculuate this through partial differientiation! Electricity travels through the shortest path of least resistance and lack of insulated wiring can cause arcing.
