Auxiliary mounting device for cultivating implements

An auxiliary mounting device for use with a tractor having a one-point hitch, the auxiliary mounting device comprising:

• (a) a body having a forward end and a rearward end with the longitudinal axis of the body extending therebetween;
• (b) tractor attachment means for attaching the body to the tractor hitch, the tractor attachment means being hinged to the forward end of the body to allow the tractor attachment means and the body to pivot relative to each other about a horizontal, transverse axis;
• (c) a primary tool mount on which a primary cultivating tool may be mounted in fixed relation to the body;
• (d) a secondary, three point mount located rearwardly of the primary tool mount and on which a secondary cultivating tool may be mounted, the three-point mount having a first and second attachment points adapted to carry the secondary cultivating tool in hinged relation to the rearward end of the body and a third attachment point located above the first and second attachment points, the third attachment point being adapted to be pivotably attached to the secondary cultivating tool;
• (e) a pedestal extending upwardly from the body and rigidly attached thereto with a first variable length shaft pivotably attached to the pedestal, the first variable length shaft also being pivotably attached to the tractor attachment means to hold the body and tractor attachment means at selected, fixed angles relative to each other, whereby the primary tool mount may be raised and lowered relative to the secondary tool mount, a second variable length shaft also being pivotably attached to the pedestal and extending rearwardly therefrom, terminating in the third attachment point, whereupon the third attachment point may be moved to selected, fixed, forwardly and rearwardly located positions by lengthening and shortening the second variable length shaft;
• and
• (f) wheels attached to the body in rotating relation, located at a selected point between the primary and secondary tool mounts, and having means for moving the wheels between a first position, wherein the wheels support and elevate the body and the primary and secondary cultivation tools are held above the ground, and a second position, wherein the primary and secondary cultivating tools are engaged in the ground and the wheels are withdrawn to a position entirely above and out of contact with the ground, wherein each of the first and second attachment points includes
• (g) two side support pieces rigidly attached to the body and extending generally parallel to the longitudinal axis thereof;
• (h) a pivot pin extending between and supported by each of the side support pieces;
• (i) a floating attachment member adapted to pivot about the pivot pin and to extend rearwardly of the body, the floating attachment member having at a point remote from the pivot pin means to engage the secondary cultivating tool in hinged relation;
• (j) a stop pin extending between and supported by the side support pieces at a location beneath the floating attachment member to limit the downward motion of the floating attachment member;
• and
• (k) means to restrain the upward motion of the floating attachment member, whereby the secondary tool mount is adapted to allow the secondary cultivating tool to float vertically within confined limits.
