The apparatus includes a pair of skids mounted upon a pivoted arm, which arm has also mounted thereon a pair of cutter wheels for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for essentially vertical movement with respect to the associated arm and cutter wheel mounted thereon to thereby determine and control the depth of furrow cut by the associated cutter wheel. A substantially circular plate has an oval aperture in the central portion through which the axle and drive for the cutter wheel extends, and an inwardly directed cylindrical flange extends to the periphery of the circular plate to protect the axle and to provide for movement of the skid relative to the cutter wheel and axle.

  • Patent number: 4016934
    Abstract: Conventional land packer wheels used in conjunction with seed drills or the like tend to pulverize the soil and often become clogged with debris. The present device gives proper soil compaction and does not pulverize or clog due to the shape of the teeth which are of a tapered diamond formation. Also the teeth extend from both sides of a disc having a central hub which positions the discs one from the other correctly. The construction is also strong enough to support the weight of the implement.

  • Patent number: 3995699
    Abstract: A replaceable tool for attachment to the periphery of an agricultural disc is formed of an inverted U-shaped investment casting which can be fitted over the marginal edge portion of the disc to present parallel leading and trailing faces connecting side surfaces which converge outwardly of the disc, being inclined at different angles relative to the plane of the disc so as to present on one side of said disc a side surface providing clearance for the disc on that side of the disc and the other side surface being at a greater angle which reduces the areas of the end faces of the tool to reduce resistance to passage of the tool through the ground.

  • Patent number: 3939917
    Abstract: A spiker blade for use on a turf spiker assembly to break and ventilate a ground surface thereby facilitating penetration of air, water and nutrient through the surface. The spiker blade has a tooth profile with a trailing edge having a counterdepression segment. The counterdepression segment functions to create a ground surface depression into which ruffled material kicked up by the tooth during spiking may be deposited. As a result, the ground surface after spiking has taken place is maintained relatively smooth with an unruffled appearance.
