Abstract
A vehicle attached rake for grooming a granular surface includes a center section and two pivotal wing sections that carry rubber trowel members having a serrated lower edge that forms a plurality of downwardly extending teeth. The tips of the teeth are located on a large diameter, upwardly facing curve to better groom upwardly curved side walls in a golf course bunker. When the rake is attached to a ZRT vehicle, the wing section on the inside of a zero radius turn is automatically lifted up off the granular surface by a flexible tether that becomes taut. Another embodiment of the rake includes a rigid plate behind a rubber trowel member with a lower portion of the trowel member folding forwardly during reverse motion of the vehicle such that the plate engages the granular surface to act as a bulldozer blade.
