Abstract
A rotor and cultivating tools are provided for a rotary cultivating machine. The rotor is of the kind having a plurality of outwardly directed cultivating tools, in the form of rods. To fix the tools to the rotor shaft the shaft has secured to it one or more helical bars extending around the shaft from one end to the other. Holes are formed in the bars and in the shaft to receive the cultivating tools. The tools have a working portion at one end and a shank at the other end. The shank extends through the bar and the shaft and is secured by a nut at the end opposite the working portion. The working portion is flattened at its outer end to present a narrower dimension to the ground being worked. The arrangement provides a shaft and tools which are cheaper to make and replace.
