Abstract

Abstract An offset adapter dimensioned to connect different farm implements in offset relation to a tractor with a three point lift. The adapter is reversible to offset the implement to the right or to the left, and it is constructed to facilitate vertical adjustments of the implement with respect to the terrain. The adapter has a bar depending from which are brackets connectable to first and second hitching points on the implement. The first bracket is rigidly mounted to the bar and is designed to be connected to one of the implement hitching points; and the second bracket may be slidably disposed along the bar, but is capable of rigid attachment at a position on the bar corresponding to the position of a second implement hitching point. Two mountings are also provided for attachment of the bar to a conventional three point lift. The unique positioning of brackets over mountings permits accommodation of implements having different width hitch points, yet also is capable of being reversed so an implement can be offset in a different direction.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 234 words
An offset adapter dimensioned to connect an implement having at least two hitching points in offset relation to the three point lift of a tractor, said adapter comprising: a bar; a first bracket depending from said bar, said bracket being adapted to be coupled to a first hitching point on the implement; and a second bracket depending from said bar, said second bracket capable of being coupled to a second hitching point on the implement, said first and second brackets being positioned along the bar so that an implement attached thereto will be offset to one side of the center of the tractor; a first mount depending from and affixed to said bar laterally of said first bracket in one direction; a second mount depending from and affixed to said bar laterally of said first bracket in the opposite direction from said first mount; and a support means upstanding from and affixed to said bar centrally of said first and second mounts, said mounts being adapted to be attached to the lower arms of the three point lift and the support means to the top arm of the three point lift, and said bar, brackets and mounts being adapted to be rotated in a plane parallel to the ground 180 degrees to permit attachment of the implement so that it is offset to the other side of the path of travel of the vehicle.
Claim 2
Dependent Claim 234 words
An offset adapter dimensioned to connect an implement having at least two hitching points in offset relation to the three point lift of a tractor, said adapter comprising: a bar; a first bracket depending from said bar, said bracket being adapted to be coupled to a first hitching point on the implement; and a second bracket depending from said bar, said second bracket capable of being coupled to a second hitching point on the implement, said first and second brackets being positioned along the bar so that an implement attached thereto will be offset to one side of the center of the tractor; a first mount depending from and affixed to said bar laterally of said first bracket in one direction; a second mount depending from and affixed to said bar laterally of said first bracket in the opposite direction from said first mount; and a support means upstanding from and affixed to said bar centrally of said first and second mounts, said mounts being adapted to be attached to the lower arms of the three point lift and the support means to the top arm of the three point lift, and said bar, brackets and mounts being adapted to be rotated in a plane parallel to the ground 180 degrees to permit attachment of the implement so that it is offset to the other side of the path of travel of the vehicle.
Claim 3
Dependent Claim 55 words
The adapter as defined in claim 1 whereby the distance between the implement and the bar is adjustable by bolting each of said first and second hitching points to one of a series of apertures provided in each of said first and second brackets for accommodating the heights of different hitching points on the implement.
Claim 4
Dependent Claim 35 words
The adapter as defined in claim 1 for use with an implement having three hitching points, which adapter further includes: means connected to said bar for attachment to a third hitching point on said implement.
Claim 5
Dependent Claim 54 words
The adapter as defined in claim 3 wherein said means includes: an arm removably attached to said bar and disposed rearwardly therefrom, said arm being reversible to permit attachment to said third hitching point on said implement when said implement is offset to a different side of the path of travel of the tractor.
Claim 6
Dependent Claim 247 words
An offset adapter dimensioned to connect an implement having three hitching points in offset relation to a three point lift tractor, comprising: a bar positionable transverse the path of the tractor and capable of being rotated by 180 degrees relative thereto for offsetting the implement on the other side of the tractor; a first bracket rigidly mounted to said bar and depending therefrom, adapted to be bolted to a first of the implement hitching points; a second bracket slidably disposed along said bar and depending therefrom, said second bracket capable of being fixed at a position on said bar to enable it to be bolted to a second of said implement hitching points, each of said first and said second brackets having a plurality of apertures vertically positioned therein to permit the height of the implement to be adjusted above the terrain by attachment of the implement hitching points to different apertures; two mountings depending from said bar, each of said mountings being adapted to receive one of the bottom arms of the three point lift tractor, said mountings being positioned on said bar offset relative to said first and second brackets so that an implement attached to said brackets will be laterally offset from said tractor; and adjustable support means connected at one end to said bar and at the other end to a third hitching point on said implement, said support means being adjustable in length to permit connection to a variety of different implements.
Claim 7
Dependent Claim 247 words
An offset adapter dimensioned to connect an implement having three hitching points in offset relation to a three point lift tractor, comprising: a bar positionable transverse the path of the tractor and capable of being rotated by 180 degrees relative thereto for offsetting the implement on the other side of the tractor; a first bracket rigidly mounted to said bar and depending therefrom, adapted to be bolted to a first of the implement hitching points; a second bracket slidably disposed along said bar and depending therefrom, said second bracket capable of being fixed at a position on said bar to enable it to be bolted to a second of said implement hitching points, each of said first and said second brackets having a plurality of apertures vertically positioned therein to permit the height of the implement to be adjusted above the terrain by attachment of the implement hitching points to different apertures; two mountings depending from said bar, each of said mountings being adapted to receive one of the bottom arms of the three point lift tractor, said mountings being positioned on said bar offset relative to said first and second brackets so that an implement attached to said brackets will be laterally offset from said tractor; and adjustable support means connected at one end to said bar and at the other end to a third hitching point on said implement, said support means being adjustable in length to permit connection to a variety of different implements.
Claim 8
Dependent Claim 43 words
The offset adapter as defined in claim 5, wherein each mounting means, spaced apart on said bar, to permit connection to the bottom lift arms of a relatively narrow three point lift and to permit connection to a relatively wide three point lift.
