Abstract
A hand-held, power driven cultivator includes a housing and cultivator blades which rotate about axes oblique to the vertical axis of the cultivator, the blades extending generally in planes which converge beneath the housing. The cultivator is driven by an electrical motor and has a power train which includes a speed reduction gear arrangement. The cultivator blades may overlap slightly as they rotate and may be formed of hardened metal or plastic. The housing of the cultivator is provided with a skirt which extends outwardly and downwardly about the sides and rear of the housing. The skirt is provided with lower depending side shield portions and a rear rake or spreading portion. The rear rake or spreading portion is formed with notches or teeth to smooth and spread cultivated dirt.
