Patent number: 5572856Abstract: A remotely controlled mower which can be easily converted to an edger, a trimmer and a blower with replaceable kits. The mower is battery powered with two drive motors (16A & B) having gear reducing means to provide rotational energy for propulsion and steering which enables the mower to turn with unlimited angles. Cutting devices for mowing, edging, trimming and blowing device are molded integrally with assemblies for easier attachment. The multiple holes on the assemblies provide a simple way to change cutting heights. Angle drives (54A & B) are used to convert the rotating directions for trimming, edging and mowing. The mower produces no air pollution with low operating noise. The combination of various functions in one remotely controllable mower not only makes lawn maintenance tasks easier but saves homeowners money to purchase and to service different equipments with less space required for storage.Type: GrantFiled: August 21, 1995Date of Patent: November 12, 1996Inventor: Chingyu J.
