Disclosed is an apparatus for disintegrating bales of agricultural material such as hay. The apparatus has a chassis, a processing tub with a discharge opening located in one of its side walls, a disintegrator mounted in the processing tub to disintegrate baled crop material positioned within the tub and discharge the processed bale material out the discharge opening and a manipulator mounted within the processing tub adapted to manipulate the baled crop material to expose different parts thereof to the disintegrator. The processing tub is adapted to be mounted on the chassis such that the discharge opening can be positioned on either the left or right side of the chassis. In an embodiment of the invention, the processing tub is sized to accommodated a large square bale lengthwise therein or two or more round bales. The apparatus is also provided with an adjustable fork lift to raise bales of different configurations into the processing tube and a hydraulic selector valve such that two sets of hydraulic systems on the processor can be operated by a single hydraulic line from a tractor or other power source.
