Abstract

Abstract A grass bagger (13) for a lawn tractor (14). The catcher (13) includes a hood (20) which directs grass clippings into a pair of bag assemblies (40). A grass checker (50), connected to hood (20), is used to check the level of accumulated grass beneath hood (20) to determine when it would be appropriate to empty bag assemblies (40) of their accumulated grass clippings. In order to prevent grass clippings from leaking between bag assemblies (40) and hood (20), and to keep hood (20) from popping open when lawn tractor (14) is driven over rough ground, a pair of latches (70) is included to releasably secure hood (20) to bag assemblies (40).

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 130 words
A grass checker for determining the level of accumulated grass within a grass catcher, comprising: (a) a handle portion located outside the grass catcher accessible by an operator; (b) a grass contacting portion connected to the handle portion and located inside the grass catcher; and (c) means for operatively disposing the grass checker relative to the grass catcher, wherein to check the level of accumulated grass in the grass catcher the operator manipulates the handle portion to move the grass contacting portion toward the accumulated grass, and wherein when the accumulated grass is contacted the operator will encounter increased resistance to movement, whereby the operator can determine based on the position of the handle portion and the degree of increased resistance the level of accumulated grass within the grass catcher.
Claim 2
Dependent Claim 130 words
A grass checker for determining the level of accumulated grass within a grass catcher, comprising: (a) a handle portion located outside the grass catcher accessible by an operator; (b) a grass contacting portion connected to the handle portion and located inside the grass catcher; and (c) means for operatively disposing the grass checker relative to the grass catcher, wherein to check the level of accumulated grass in the grass catcher the operator manipulates the handle portion to move the grass contacting portion toward the accumulated grass, and wherein when the accumulated grass is contacted the operator will encounter increased resistance to movement, whereby the operator can determine based on the position of the handle portion and the degree of increased resistance the level of accumulated grass within the grass catcher.
Claim 3
Dependent Claim 54 words
The grass checker of claim 1, wherein: (a) the grass catcher comprises a bag assembly and a hood; and (b) the disposing means comprises an aperture in the hood which receives the grass checker, with the grass contacting portion being within and beneath the hood and the handle portion being located outside the hood.
Claim 4
Dependent Claim 16 words
The grass checker of claim 2, wherein the grass checker is pivotably mounted to the hood.
Claim 5
Dependent Claim 40 words
The grass checker of claim 3, wherein the checker has a first unactivated state, wherein the handle is in a lowered position, and a second activated state, wherein the handle is in a raised position relative to its lowered position.
Claim 6
Dependent Claim 19 words
The grass checker of claim 4, wherein gravity alone causes the grass checker to normally assume its unactivated state.
Claim 7
Dependent Claim 63 words
The grass checker of claim 1, wherein: (a) the grass catcher comprises first and second bag assemblies and a hood mounted thereupon, the hood forming a grass inlet; (b) the grass inlet is closer to the first bag assembly than the second bag assembly; and (c) the grass checker is disposed to determine the level of accumulated grass within the first bag assembly.
Claim 8
Dependent Claim 106 words
The grass checker of claim 1, wherein the grass catcher comprises a hood and a bag assembly; the grass checker is pivotably secured to the hood, and has a generally vertical unactivated state wherein the handle portion is in a lowered position, and a generally horizontal activated state wherein the handle portion is in a raised position relative to its lowered position; and wherein the balance of the grass checker is such that it assumes its unactivated, generally vertical state when it is not being actively moved from the unactivated state to the activated state to determine the level of accumulated grass within the bag assembly.
Claim 9
Dependent Claim 55 words
The grass checker of claim 1, wherein: (a) the grass catcher comprises first and second bag assemblies and a hood mounted thereupon; (b) the second bag assembly tends to fill prior to the first bag assembly; and (c) the grass checker is disposed to determine the level of accumulated grass within the first bag assembly.
Claim 10
Dependent Claim 297 words
A grass mowing and catching apparatus comprising: A. a traction vehicle; B. a rotary mowing deck operatively connected to the traction vehicle, the deck having a discharge chute; C. a discharge tube extending upwardly from the mowing deck discharge chute, the discharge tube having an upper end; D. a grass catcher comprising first and second bag assemblies operatively connected to the traction vehicle and a hood disposed above the bag assemblies, wherein the hood comprises a wall which forms an opening receiving the upper end of the discharge tube, wherein the second bag assembly tends to fill at a faster rate than the first bag assembly; and E. a grass checker pivotably connected to the wall of the hood and extending through a grass checker aperture formed thereby, the grass checker being disposed proximate to the first bag assembly and comprising: (1) a handle portion located outside the hood; and (2) a grass contacting portion connected to the handle portion and located beneath the hood, wherein: (a) the grass checker has a first unactivated state wherein the handle is in a lowered position, and a second activated state, wherein the handle is in a raised position relative to its lowered position; (b) gravity alone causes the grass checker to normally assume its unactivated state; and (c) to check the level of accumulated grass in the first bag assembly the operator manipulates the handle portion of the grass checker to move the grass contacting portion toward the accumulated grass within the first bag assembly, wherein when the accumulated grass is contacted the operator will encounter increased resistance to movement, whereby the operator can determine based on the position of the handle portion and the degree of increased resistance the level of accumulated grass within the first bag assembly.
Claim 11
Dependent Claim 297 words
A grass mowing and catching apparatus comprising: A. a traction vehicle; B. a rotary mowing deck operatively connected to the traction vehicle, the deck having a discharge chute; C. a discharge tube extending upwardly from the mowing deck discharge chute, the discharge tube having an upper end; D. a grass catcher comprising first and second bag assemblies operatively connected to the traction vehicle and a hood disposed above the bag assemblies, wherein the hood comprises a wall which forms an opening receiving the upper end of the discharge tube, wherein the second bag assembly tends to fill at a faster rate than the first bag assembly; and E. a grass checker pivotably connected to the wall of the hood and extending through a grass checker aperture formed thereby, the grass checker being disposed proximate to the first bag assembly and comprising: (1) a handle portion located outside the hood; and (2) a grass contacting portion connected to the handle portion and located beneath the hood, wherein: (a) the grass checker has a first unactivated state wherein the handle is in a lowered position, and a second activated state, wherein the handle is in a raised position relative to its lowered position; (b) gravity alone causes the grass checker to normally assume its unactivated state; and (c) to check the level of accumulated grass in the first bag assembly the operator manipulates the handle portion of the grass checker to move the grass contacting portion toward the accumulated grass within the first bag assembly, wherein when the accumulated grass is contacted the operator will encounter increased resistance to movement, whereby the operator can determine based on the position of the handle portion and the degree of increased resistance the level of accumulated grass within the first bag assembly.
