Abstract
A leaf receptacle bag is affixed to a vertically disposed support surface that has means for adapting to a leaf conduit. The leaf conduit conveys leaves from a tractor vacuum unit through an orifice in the vertically disposed support surface, the adapter of the conduit directing the leaves diagonally across the interior of the leaf receptacle bag to thereby deposit the leaves at the lower portion of the bag.
Claims4
A leaf bagger, connected to an undercarriage leaf vacuum mechanism of a lawn tractor, comprising:
- a leaf conduit;
- said conduit rigidly affixed to a vertically disposed support frame;
- said support frame being structurally housed in a vertically disposed support surface;
- said support frame being rigidly affixed to said tractor structure;
- said leaf conduit having an upwardly disposed terminal thereon, said upwardly disposed terminal having a leaf bag adapter circumferentially affixed thereto;
- said leaf conduit, support frame, and support surface being, in combination, disposed to the rear of a tractor unit such that said leaf conduit extends transversely from said upwardly disposed leaf conduit adapter to said tractor undercarriage vacuum mechanism;
- a leaf receptacle bag;
- said leaf receptacle bag affixed to said vertically disposed support surface;
- said leaf receptacle bag having a leaf conduit orifice disposed proximate to said support surface;
- said leaf conduit extending therethrough such that leaves are blown, by the action of said leaf vacuum mechanism, into said leaf receptacle bag;
- said leaf receptacle bag forming thereby an oblique angle with said leaf conduit and thereby dragged behind the lawn tractor;
- said conduit depositing leaves within said leaf receptacle bag;
- said leaves becoming deposited at the lower, rearward portion thereof through the action of gravity and through the action of the tractor device moving over the earth and dragging the bag;
- whereby, leaves are propelled in a transverse, upward motion by the tractor mechanism, thence into said receptable bag and downward, along a slope formed by the interior of said leaf bag receptacle, to a rear-lower portion thereof;
- said leaf receptacle bag has an air outlet;
- said air outlet disposed along the upper surface thereof, whereby excess air from said leaf vacuum device escapes from said leaf receptable bag;
- said air outlet is a mesh strip, said mesh strip being disposed to the upper layer of said receptable bag;
- said air outlet strip being disposed along a longitudinal axis of said leaf bag receptacle;
- whereby said leaf receptacle bag is partially inflated with air from said tractor leaf vacuum unit, with the further result that air flows stream like along said longitudinal axis of said leaf receptacle bag, carrying therewith leaves, which subsequently fall to the bottom of said leaf receptacle bag as said air moves through said longitudinally disposed air outlet;
- said air outlet strip is disposed only along a upper one half portion of said leaf receptacle bag, as measured longitudinally along the bag, from bottom to top;
- said receptacle bag has fastening means deployed transversely across a bottom portion thereof whereby said receptacle bag may be emptied by restoring said fastening means;
- said fastening means is a hook and loop strip fastening means.
