ABSTRACT:
A hydraulic bumper mechanism for moving bales. A modified rear bumper is used on pick up trucks. Extending forwardly from the bumper is a pair of spaced apart housings which retain hydraulic cylinders. The front end of the cylinders and the piston portion thereof faces to the rear of the truck and each is attached to a receptacle that is rotatably attached to a common shaft. These receptacles are adapted to receive round bale piercing spears. When in the horizontal position as the truck is backed up into the bale these spears stab into the bales. Once the bale is stabbed, the hydraulic cylinders are actuated outwardly to cause rotation of the receptacles, of the spears and of the attached round bale of hay. A variety of other tools can be used with it and include a wire winder and a pallet mover. An auxiliary hydraulic kit is also incorporated with the modified bumper.
