| 20110254241 | CASTER WHEEL SUSPENSION FOR A ZERO-TURN MOWER - A zero-turn mower comprising a zero-turn mower frame, a front axle coupled to the zero-turn mower frame, first and second caster wheel assemblies, and first and second front shock assemblies. The front shock assemblies rotatably and telescopically couple the caster wheel assemblies to the front axle, thereby providing vertical shock absorption. The front axle may be a floating axle that is pivotably coupled to the mower frame and/or the shock assemblies may define an internal spring-receiving chamber that is substantially isolated from the external environment. Such a zero-turn mower may provide a smoother ride and may require less maintenance and repair than conventional zero-turn mowers. | 10-20-2011 |
| 20110155031 | Seed Furrow Closing Apparatus - A seed furrow closing wheel has a generally dish-shaped body defined by a central portion and a notched outer flange portion that circumscribes the central portion and projects obliquely outwardly from the plane thereof. The notched flange portion is configured to present a series of circumferentially spaced, non-radial, obliquely projecting teeth that function to fragment and squeeze together opposite sidewalls of the seed furrow when a pair of the wheels are rolled along opposite sides of the furrow outboard of the furrow itself, crumbling the sidewalls and covering the seeds. | 06-30-2011 |
