Abstract

A tandem hitch that automatically steers a second implement so it will properly trail a first implement around corners. The hitch attaches to a tractor's three point hookup, so it is held stationary on the tractor. The first implement or attachment attaches to the back of the tractor. The second implement or implement attaches to the back of the self steering tandem hitch. A first steering apparatus maintains the implement in a proper following position during cornering by rotating the rear wheel assembly. The whole wheel assembly is rotated by the steering apparatus for proper following positioning. Without the automatic steering the second implement would underswing or overswing leaving an area untouched. The steering action accomplished by this device steers the second implement to give a true and correct trailing of the second implement. The self steering tandem hitch is generally described as having a front upright support, a main beam, a rear upright support, an axle assembly, a first steering apparatus and a second steering apparatus. The bottom end of the front upright support is attachable to a three point hitch on a tractor. The main beam is pivotally and rotatably attached to the top end of the front upright support. The rear upright support is attached to the rear end of the main beam. The axle assembly is rotatably attached to the lower end of rear upright support. The first steering apparatus rotates the wheel assembly in respect to the main beam to automatically steer the rear end of the self steering tandem hitch during turning and cornering. The rotation of the wheel assembly during turning and cornering maintains alignment of a second farm implement attached to the rear end of the self steering tandem hitch. A first farm implement being attached directly to the tractor. The second steering apparatus pivots the wheels to hold and maintain the second or rear farm implement in a left or right offset position.
