Abstract

The instant invention is an electric machine/tractor particularly intended for farming, gardening and landscaping and is nonpolluting and self charging. The tractor accommodates standard farm implements and can supply electrical power to remote areas. To achieve these goals, the machine is comprised of a frame and wheels which are driven independently by hydraulic motors powered by a variable volume, hydrostatic pump that is driven in line, by an electric motor that also drives a hydraulic lift pump and a power-take-off shaft through belts. The hydrostatic pump is controlled by the operator for forward and reverse motion. The electric motor is powered by batteries and the batteries can be recharged by an on-board photoelectric panel. A combination charger/inverter is located aboard the tractor to charge the batteries from any 110V A.C. power outlet or generate 110V A.C. electrical power from the tractor.
