  • Patent number: 7500284
    Abstract: A turf sweeping machine having a frame, front and rear wheels coupled to the frame and an elongated chute mounted to the frame, the chute having an exit and an entrance at a level proximate to the grass of the turf. Rubber skirts are affixed to the chute and extend down to the grass of the turf across front, rear, and side walls of the chute. A rotatable brush is mounted to the frame, proximate to a bottom of the chute and extends across a width of the frame so that the brush brushes grass of a turf support surface. A hopper, which is also mounted on the frame, has an opening in fluid communication with the exit of the chute, and is positioned to receive material swept up the chute by the brush. A partial vacuum is created by rotation of the brush within the confines of the skirts and chute. This vacuum assists the brush in picking up waste material from the support surface.
