Portable power operated cultivator with axially adjustable shield

Abstract

A portable power operated cultivator includes a power unit comprising an internal combustion engine having a handle portion and being connected to one end of an elongated boom. A right angle gear drive mechanism is mounted on the opposite end of the boom and is driveably interconnected with the power unit by an elongated drive shaft disposed within the boom. An output shaft extends from opposite sides of the gear drive unit and is adapted to mount respective rotary cultivator blades on the ends thereof. A second handle is adjustably mounted on the boom to provide for a balanced weight distribution of the cultivator unit. The spaced apart cultivator blades are identical and include a plurality of radially projecting ground engaging tines. Adjacent tines on each blade have tip portions which are bent in the opposite direction with respect to each other along a bend line which provides for a positive angle of incidence or entry of the tine into the earth being worked by the cultivator. The tines of one blade are angularly offset with respect to the tines of the other blade to enhance the digging action of the cultivator unit.
