Abstract
The present invention relates to the wheel assembly of mowers, particularly to mulching mowers. In the preferred embodiment, each wheel assembly includes a clearing disc sandwiched between a pair of support wheels. The support wheels support the weight of the lawn mower. The clearing disc clears accumulated grass from the wheel assembly by moving between the support wheels as the wheels rotate to clear away grass clippings. The clearing disc has an outside diameter that is greater than the outside diameter of the support wheels and is mounted between the wheels in such a way that the clearing disc continually moves upwardly as the mower is moved.
Claims18
A wheel assembly for use on a mower for reducing the accumulation of grass clippings on the mower wheels, said wheel assembly comprising:
- at least an outer wheel and an inner wheel each having substantially the same outer diameter, said outer and inner wheels being coaxially mounted upon said mower such that said mower is supported upon said outer and inner wheels;
- clearing means for clearing away accumulated grass, said clearing means being mounted between said outer and inner wheels to clear away grass clippings as said mower is propelled, said clearing means being a clearing disc having an outer diameter that is greater than the outer diameter of said inner and outer wheels, said clearing disc being mounted for generally vertical movement with respect to said inner and outer wheels such that said clearing disc clears accumulated grass from said wheel assembly;
- whereby, as said mower is propelled, said clearing means is constantly forced between said inner and outer wheels to dislodge grass clippings that are accumulating on said wheel assembly.
A wheel assembly for use on a mower for reducing the accumulation of grass clippings on the mower wheels, said wheel assembly comprising:
- at least one weight bearing wheel mounted upon said mower such that said mower is supported upon said wheel;
- a clearing disc mounted adjacent said wheel to clear away grass clippings as said mower is propelled, said clearing disc having an outer diameter that is greater than the outer diameter of said wheels, said clearing disc being mounted for movement with respect to said wheel;
- whereby, as said mower is propelled, said clearing disc is constantly forced vertically with respect to said wheel to dislodge grass clippings that are accumulating on said wheel assembly.
An improved mower comprising:
- a plurality of wheel assemblies mounted upon said mower;
- said wheel assemblies including at least a pair of support wheels for supporting said mower, said support wheels defining a space between them, said support wheels including at least an outer wheel and an inner wheel each having substantially the same outer diameter, said outer and inner wheels being coaxially mounted upon said mower such that said mower is supported upon said outer and inner wheel;
- a clearing means positioned in said space for clearing accumulated grass from said support wheels as said support wheels rotate, said clearing means including a clearing disc mounted between said outer and inner wheels to clear away grass clippings as said mower is propelled, said clearing disc having an outer diameter that is greater than the outer diameter of said inner and outer wheels;
- whereby, as said mower is propelled said clearing means clears grass from said support wheels.
A wheel assembly for use on a mower for reducing the accumulation of grass clippings on the mower wheels, said wheel assembly comprising:
- at least an outer wheel and an inner wheel each having substantially the same outer diameter, said inner and outer wheels being coaxially mounted upon said mower such that said mower is supported upon said inner and outer wheels, said inner and outer wheels defining a space between them;
- a rod for clearing away accumulated grass, said rod being mounted on said mower and extending from said mower into said space to clear accumulated grass clippings from said inner and outer wheels;
- whereby, as said mower is propelled, said rod is constantly forced between said inner and outer wheels to dislodge grass clippings that are accumulating on said wheel assembly.
A wheel assembly for use on a mower for reducing the accumulation of grass clippings on the mower wheels, said wheel assembly comprising:
- at least an outer wheel and an inner wheel each having substantially the same outer diameter, said outer and inner wheels being coaxially mounted upon said mower such that said mower is supported upon said outer and inner wheels, said inner and outer wheels defining a space between them;
- a clearing means for clearing away accumulated grass, said clearing means positioned between said outer and inner wheels to clear away grass clippings as said mower is propelled;
- whereby, as said mower is propelled, said clearing means is constantly forced between said inner and outer wheels to dislodge grass clippings that are accumulating on said wheel assembly.
