<p>A turf grooming vehicle including a chassis and wheels supporting the chassis in terrain-following movement across a field includes a vacuum head assembly and a bin forming a receiver for loose turf material vacuumed from the surface of a field of turf. By jacking the receiver upwardly to pivot about an elevated axis of rotation the contents thereof can be discharged over the side of and into a vehicle disposed alongside the chassis. In addition, means forming a drive connection for operating both a fan for creating the suction as well as for operating hydraulic means for driving a rotatable grooming unit is coupled to a tractor or other pulling means so that the tractor and trailer can make extremely sharp turns. Further, the vacuum head assembly is arranged whereby it follows the surface of the ground idependently of upward movements of the chassis (such as may be derived from the upward movements of the chassis wheels). Finally, means are arranged for evenly lifting and lowering opposite ends of the vacuum head assembly into and out of operative relation with the ground.</p> |
