Abstract
A hydraulically powered unit which serves as a rear truck bumper and as a bale carrier for large cylindrical hay bales. The unit includes a pair of stationary end bumper sections and a pivotal center bumper section having a pair of sockets for receiving bale piercing spears. A rigid frame secures the bumper to the truck at the customary location for the rear bumper. The center bumper section can be pivoted by hydraulic cylinders in order to load an impaled bale into the truck bed for transport and to unload the bale back onto the ground. Spring loaded locking plates hold the spears in the sockets and can be released to permit removal of the spears when they are not needed to handle bales.
