Claim 1
Independent Claim
231 words
A ratooning implement comprising a tool bar adapted to be mounted on the three point linkage of a tractor, at least one pair of cutting disc units each having a movable and rotatable cutting disc, the cutting disc of each unit being positionable in rubbing overlapping relationship, said units being mountable on the tool bar, the discs lying in planes which when the tool bar is mounted on the tractor and lowered to operative position would be substantially parallel to the surface of the soil over which the implement is intended to pass, said tool bar comprising a main section adapted to be fastened to said three point linkage, extensions projecting from said main action, said extensions being clampable on the main section with adjacent extensions interleaving to mutually support each other, said first-mentioned extensions each including a Z shaped bar of uniform rectangular cross-sectional shape secured to said main section, a pair of plates at one extremity of each said extension, said plates being spaced apart to engage parts of the main frame and receive a portion of an adjacent one of said Z shaped bar, each pair of plates having openings therein, a wedge being received in each said opening whereby the main frame part on which the Z shaped bar is mounted is clampable between part of said Z shaped bar lying between said plates and said wedge.
