ABSTRACT:
A sand grooming vehicle comprises a vehicle having zero radius turn capability. The vehicle includes a front caster wheel, two independently driven rear wheels, and twin control sticks for allowing spin turning of the vehicle by driving the outboard drive wheel and stopping or reversing the inboard wheel. A trailing brush rake is towed behind the vehicle to groom the sand. The brush rake includes a center brush and two pivotal side brushes connected to opposite ends of the center brush. The pivots connecting the side brushes and the center brush are elevated above the plane of engagement of the bristles of the side brushes and the sand. Thus, during a spin turn of the vehicle, the side brush on the inside of the turn lifts to avoid pushing a ridge of sand behind that side brush. This permits the vehicle and the brush rake to groom the sand surface without leaving any ungroomed teardrops at the inside of turns and without leaving ridges of sand on the sand surface.
