Abstract

A grass and leaf collector and compactor attachment for lawn mowers consisting of a chute adapted to be mounted at the side of a mower hood to receive mower cuttings ejected from the hood in the lower end thereof, and chute angling upwardly into a hopper also adapted to be mounted on the mower, and one or more paddle bars extending generally longitudinally through the chute and having paddles secured transversely thereto at intervals along their lengths. The paddle bars are driven in vertical orbital paths by suitable connection to a ground-engaging drive wheel of the mower, so as to impel cuttings received in the lower end of the chute upwardly through the chute into the hopper. The hopper is at a sufficient elevation above ground level that its contents may be dumped by dropping the floor thereof.

In combination with a power propelled mower having cutting blades disposed beneath a hood and operable to eject cuttings through a side opening of said hood, an attachment for collecting said cuttings comprising:

a. a hollow chute attached to said mower at the side thereof, having a side opening generally registering with the side opening of said hood to receive said cuttings therein, and being elongated rearwardly from said side opening,
b. a receptacle supported by said mower rearwardly of said chute, and into which the open rearward end of said chute projects, and
c. power operated mechanical impelling means disposed within said chute and operable when driven to impel cuttings rearwardly from said chute side opening, through said chute and into said receptacle, said impelling means comprising a paddle bar extending generally longitudinally through said chute and a series of paddles affixed to said paddle bar generally transversely thereof, and in spaced relation along the length of said paddle bar, the rearmost of said paddles being disposed generally in the open rearward end of said chute, mounting means for said paddle bar whereby it may be pivoted vertically about a horizontal transverse axis at the forward end of said chute, and moved longitudinally of itself within said chute, said mounting means comprising a guide rod pivoted at its forward end in the forward end of said chute on a horizontal transverse axis, and extending rearwardly in said chute, said paddle bar being mounted for coaxial sliding movement on said guide rod, and means connecting a point of said paddle bar spaced rearwardly from the pivot of said guide rod to a power-driven member having an orbital path lying in a vertical plane, and power-operated means for moving said member, whereby said paddles sweep rearwardly along the floor of said chute in the lower portions of their orbits, and move forwardly in spaced relation above said chute floor in the upper portions of their orbits.
