ABSTRACT:
A cultivating machine having a body, at least one wheel supporting the body during normal use, and one or more soil-working blades. The blade(s) may be either serrated or generally V-shaped so that it can penetrate the soil and loosen it. The blade(s) is preferably rounded, so that it loosens the soil and pulls weeds out by the roots rather than cutting the tops of the weeds off and leaving the bottoms of the weeds in the ground to regrow, and the blade or at least one of the blades preferably projects laterally beyond the body of the cultivator on at least one side so that the cultivator may be used to loosen the soil and to pull out weeds underneath overhanging leaves of desirable plants without damaging the desirable plants by contact with moving parts of the cultivator. A motor may be mounted on the body and operatively connected to either or both of the wheel and the blades.
