Abstract: The bedding groomer comprises a frame attachable to an ag vehicle such as a skid loader or tractor for movement down the alley of a free stall barn. Pivotally supported on the frame is an elongate shroud that can be moved from a raised travel position to a lowered, laterally extending working position by a hydraulic cylinder. Rotatably mounted within the shroud is an elongated arbor driven by a hydraulic motor. Along the length of the arbor is a plurality of radially projecting tines. As the ag vehicle travels down the alley, the tines dig into the animal bedding material, churning it, to break up hard packed and compressed areas and to aerate deep within the bedding to aid in aerobic composting any organic material, such as manure, that is present in the bedding.
