Sweeper

A lawn-sweeper is a key machine used to pick up leaves and similar debris from the floor, collecting them in a net. As the lawn sweeper moves, the rotation of the wheels causes the brushes to comb through the grass, dislodging any debris or grass clippings, and then tossing the material into the rear hopper (sometimes called a bag). Once the hopper gets full, you simply dump its contents into the trash or onto a pile for disposal.
