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.

Abstract: A mower is suspended from a frame and includes a header with a cutter. A tongue is pivotally connected to the mower frame and is moveable with respect to the frame by a hydraulic cylinder. At the front of the tongue is a front gearbox rigidly attached to the tongue. The front gearbox transmits rotary power from the power take off of the tractor to a rear gearbox pivotally attached the header and from the rear gearbox rotary power is passed on ultimately to the rotary cutting units. Pivoting of the rear gearbox is controlled by a steering connection operatively attached between the front and rear gearboxes.

Abstract: A rotary broom mounts upon a slotted plate that pivots upon a double gearbox. The broom has bristles upon an axle within a shield that receives power from a chain drive that receives its power from a driveline from a top gear box. The top gearbox orients in the direction of the chain driveline and delivers its power through an output shaft. The top gearbox joins to a slotted plate that turns in the same direction as the broom. The top gear box receives its power through an input shaft perpendicular to the output shaft. The top gearbox input shaft extends downwardly and becomes the output shaft of the bottom gearbox. The bottom gearbox has an input shaft that connects to a power take off. This rotary broom receives rotational power, rotates it 90° upwardly, then rotates it 90° downwardly and at an angle laterally to drive the broom.
