Abstract

Abstract An adapter for enabling a tractor having a three point hitch to pull an implement designed for connecting to a sleeve hitch. The adapter comprises a frame with two parts, one part attachable to a three point hitch and a second part having a hole for receiving a pin to connect the adapter to the bracket of an implement. Two bolts, one on either side of the hole for the connecting pin, can be turned to threadingly engage the bracket and thereby prevent rotation of the implement about the pin. The three points of the adapter to which the tractor attaches are two spaced apart, coaxial bars and a member with a throughhole in it, located above and between the two bars, all connected to the frame.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 233 words
An adapter for use in connecting an implement to a tractor having a three point hitch, said implement having a connecting bracket carrying a pin, said adapter comprising: a frame having two spaced apart, threaded holes and a first bar, a second bar spaced apart from said first bar and coaxial therewith, and a member positioned between and above said first and said second bars and between said first and second threaded holes of said frame, said member having a throughhole having an axis, said member lying in a plane substantially perpendicular to said first and second bars, said axis of said throughhole being parallel to said first and said second bars, said first and said second bars and said throughhole of said member engaging said three point hitch of said tractor; a receiving means having a tube attached to said frame between said first bar and said second bar, said tube dimensioned for receiving said pin and having an axis, said axis of said tube being substantially in said plane so that said pin of said implement will be substantially aligned with said throughhole; and two threaded bolts, each threaded bolt threaded into one threaded hole of said two threaded holes until said threaded bolt engages said bracket when said pin of said bracket is received in said receiving means, said two threaded bolts preventing rotation of said implement about said pin.
Claim 2
Dependent Claim 233 words
An adapter for use in connecting an implement to a tractor having a three point hitch, said implement having a connecting bracket carrying a pin, said adapter comprising: a frame having two spaced apart, threaded holes and a first bar, a second bar spaced apart from said first bar and coaxial therewith, and a member positioned between and above said first and said second bars and between said first and second threaded holes of said frame, said member having a throughhole having an axis, said member lying in a plane substantially perpendicular to said first and second bars, said axis of said throughhole being parallel to said first and said second bars, said first and said second bars and said throughhole of said member engaging said three point hitch of said tractor; a receiving means having a tube attached to said frame between said first bar and said second bar, said tube dimensioned for receiving said pin and having an axis, said axis of said tube being substantially in said plane so that said pin of said implement will be substantially aligned with said throughhole; and two threaded bolts, each threaded bolt threaded into one threaded hole of said two threaded holes until said threaded bolt engages said bracket when said pin of said bracket is received in said receiving means, said two threaded bolts preventing rotation of said implement about said pin.
