摘要： An apparatus for finely pulverizing lawn debris has a central drive shaft driven by a gasoline or electrical power source. Lawn debris is drawn into a suction and grinding chamber by the rotation of a distribution plate which has a plurality of curved impeller blades permanently attached to a perforated plate. A grinding blade with a plurality of blade elements is mounted on the central drive shaft above the distribution plate and effects pulverization of the debris. The distributing plate apertures dispense the pulverized debris uniformly over a lawn. Optionally, additional fan impeller blades may be mounted on the central drive shaft to draw and initiate pulverization of the debris. In this case, the rotation of the distributing plate may be stopped by disengaging a clutch mounted on the central shaft to direct pulverized debris to a side collection chamber, which is periodically emptied through a bottom discharge gate.

摘要： An apparatus for finely pulverizing lawn debris has a central drive shaft with a clutch driven by a gasoline or electrical power source. Lawn debris is drawn into a suction chamber by a fan impeller blade mounted on the central drive shaft. The fan impeller blade initiates pulverization of the debris. A grinding blade with a plurality of blade elements is mounted on the central drive shaft below the fan impeller blade and effects additional pulverization of the debris. A clutch is mounted next on the drive shaft followed by a distributing plate with a plurality of inclined apertures for dispensing a high velocity stream of the pulverized debris uniformly over a lawn from the rotating distributing plate. When the clutch is disengaged the distributing plate rotation is stopped and the finely pulverized garden debris is collected in a side collection chamber and is periodically emptied through a bottom discharge gate.

摘要： An apparatus for finely pulverizing lawn debris has a central drive shaft driven by a gasoline or electrical power source. Lawn debris is drawn into a sucking chamber by a fan impeller blade mounted on the central drive shaft. The fan impeller blade initiates pulverization of the debris in the suction chamber. A grinding blade is mounted for rotation on the central drive shaft below the fan impeller blade. The grinding blade carries a plurality of blade elements operative to effect additional pulverization of the initially pulverized debris. A distributing plate mounted for rotation on the central shaft has a plurality of inclined apertures therein for dispensing a high velocity stream of the pulverized debris uniformly over said lawn.
