Claim:
1. A drawbar hitch conversion unit for a planter that is arranged to have a two-point hitch unit coupled to a longitudinal pull tongue of the planter near a forward end thereof by a pivotal connection through an upright bore in the pull tongue, the drawbar hitch conversion unit comprising: a frame comprising: a tongue extension pivotally coupled to the frame for pivoting of the tongue extension in an upright plane about a pivot axis passing laterally through the upright planes of the side plates, the tongue extension reaching forwardly from the side plates to a front end of the tongue extension that is arranged for coupling to a drawbar hitch of a tractor; an opening spanning through the at least one cross member from a topside thereof to an opposing underside thereof to accommodate passage of a coupling pin through said opening in a manner also passing through the upright bore of the pull tongue of the planter when said upright bore of the pull tongue is aligned with said opening in the at least one cross member, thereby coupling the hitch conversion unit to the pull tongue of the planter; an actuator connected between the frame and the tongue extension and operable to effect raising and lowering of the front end of the tongue extension relative to the frame about the pivot axis; and a clamping mechanism on the frame that is operable to clamp the pull tongue securely between the side walls of the frame at a longitudinally spaced distance from the opening in the at least one cross-member when the frame is connected to the pull tongue by the coupling pin.
