  • Patent number: 4297760
    Abstract: The invention is an improved device for picking leaves, pine needles, and other debris from a lawn and bagging them for disposal. The device operates by the movement of a pair of wheels across the lawn, which in turn, by geared means, revolves a shaft carrying a plurality of rake-like tines or fingers. The rake-like members, on the revolving shaft, sweep and pick up leaves and other debris from a lawn and move them upward within the housing of the device. The rake-like members extend outwardly from the shaft and the ends pass through apertures in a drum. The drum is off-center in relation to the shaft of the rake-like members so that in the revolving of the mechanism the ends of the rake-like members move back and forth through the apertures in the drum. The leaves and other debris are moved and compacted into a disposal bag mounted to the upper side of the mechanism. The filled disposal bag is easily removed and replaced by an empty bag. Handle means are provided for manually pushing the device.
