ABSTRACT:
A cultivating tool having a U-shaped tubular frame defining a handle which may be gripped by an operator, and two hollow legs which latter house respective anchor legs biassed outwardly by means of a respective coil spring (not shown). A housing mounted between the legs contains a power source such as an electric motor and gearbox (both not shown) controlled by a switch on the handle and driving, via a reduction drive unit, a pair of cultivator rotors. In use, the legs are pushed into the ground against the pressure of the coil springs, a control being provided to ensure that the rotors cannot rotate until pressure has been applied to the anchor legs.
