General Electric Elec-Trak Lawn Tractor, Model E15

While the GE Delta experimental car created interest for electric vehicle technology, its batteries were too heavy and its range too short for commercially successful transportation. The weight and short range were ideal for electric tractors and in 1970 GE entered the electric lawn tractor market with its Elec-trak line. GE sold 30,000 tractors in four years, but did not capture enough of the lawn tractor market, and sold the product line to Wheel Horse in 1974.
