They were used in one area or another from a few months after the end of World War II until a few months after the end of U.S. participation in the Vietnam War – from 1946 until 1973.
The “Power Mower of the Future” is demonstrated in Port Washington, Wis., Oct 14, 1957. The lawnmower has a five foot diameter plastic sphere in which the rider sits on an air foam cushioned seat. It has its own electric generating system for operating running lights, a radio telephone, air conditioning and even a cooling system to provide a chilled drink on a hot day. It can be used for many purposes. It can mow the lawn, weed it, feed it, seed it, spray for insects, plow snow and haul equipment. It can even be used as a golf cart.
