Hustler Zeon Electric Mower
The Hustler Zeon, the world’s first all-electric zero-turn-radius mower, shows what an environmentally friendly piece of yard machinery can do. The four 12-volt lead-acid batteries power twin DC deck motors, driving a pair of blades for a 42-inch-wide cut. The batteries also power twin AC hydrostatic drive motors, one at each rear wheel. The machine can turn on a dime or zoom along at 6 mph. The run time is 80 minutes, long enough to cut an acre. The Zeon costs about $7,000.
