The huge difference between cars and tractors is how much power they need to develop on a continuous basis. It only takes about 15-20 horsepower to propel a reasonably aerodynamic sedan at highway speeds on level ground, about the same amount of power as an average riding lawn mower. Compared to a tractor putting out 75 hp a given battery capacity would last 4 to 5 times longer in the car. Or, put another way, the tractor's battery would have to be 4 to 5 times as large to get the same hours of use between charges. And, every time the car slows down the battery can be recharged a bit with regenerative braking which there is no ability for in most tractor applications. Large batteries are expensive and for most tractor applications it just doesn't make financial or practical sense yet. It all comes down to the fact that the power density of batteries is still greatly less than the power density of gasoline or diesel fuel, even with the recent rapid progress of battery technology. This is a significant limiting factor in converting mobile machines from petroleum to electric power.

It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer.
