Cultivators; ploughs. -- A rotary-tool implement comprises a cone-shaped body 27, Fig. 3, around which is welded or otherwise secured a spiral steel flange 28, the screw thus formed being detachably secured to a spindle 19 supported by triangular frames 17 from the main frame 10 and rotated by gearing from the wheel shaft 22. The front end of the frame 10 is adjustably mounted in the wheel standard 12. In a modification, Fig. 4, the screw is formed of curved blades 25 radiating from a coneshaped body and terminating in a spiral 26. In another form of Fig. 3, the flange 28 only encircles the body 27 once. Reference has been directed by the Comptroller to Specifications 3798/96, 19,696/97, 23,606/97, and 12,658/06.
