  • Publication number: 20130019787
    Abstract: This planting device has a rotary excavator head instead of a plow to make a furrow The excavator uses a various number of teeth to cut the soil and two flat plates and centrifugal force to distribute the soil evenly around the hole to be excavated for planting. The cutting action of the teeth breaks up the soil into a very fine media. The two flat plates use centrifugal force to distribute it evenly around the hole. The rotary excavator can be of several different sizes (8-24 inches) on the hand operated models and up to 36 inches on the three point hitch tractor mounted models. The hand operated model has long handles and wheels to counter act the rotating torque generated by the power head and excavator.

  • Patent number: 6003453
    Abstract: An apparatus for sowing seeds in a plurality of identical furrows is described. The seed sowing apparatus comprises a scraper, seed tubes, a packer and a cylindrical drum with a plurality of ground engaging flanges attached around its periphery. All of the components of the seed sowing apparatus are mounted in a frame arranged for ground transportation. In operation, the cylindrical drum rolls over the ground so that the flanges engage the ground and then release, thereby generating furrows. The seed tubes deposit seeds into the furrows before the scraper directs soil into the furrows, thereby enclosing the seeds. Lastly, the packer compresses the soil enclosing the seeds, thereby promoting synchronous germination of the crop.

  • Patent number: 5970892
    Abstract: A shallow-toothed clearing disk pivotally supported from the upper end of the opener drawbar assembly. A four bar linkage is connected to the forward end of the drawbar by a bracket which includes at least one link and corresponding pivot structure located above the drawbar to increase trash clearance and reduce trash build-up. The shallow rounded gullets between pointed teeth provide good disk depth control and trash penetration while reducing soil penetration and soil disturbance. The gullets also hold and prevent sliding of trash away from the clearing influence of the angled disk. The disk effectively clears trash to the side of the opener opposite the gauge wheel to assure optimum depth gauging for the opener. The gear-type structure is capable of operating over a wide range of down pressures and loads while breaking any existing crust in the cleared path with little soil disturbance.

  • Patent number: 5685246
    Abstract: A seed drill includes a novel planting assembly combining press wheels for packing angular sides of a furrow and a runner immediately behind and longitudinally aligned with the press wheel. The runner includes an arcuate front edge that is juxtaposed immediately behind the coulter, thereby preventing accumulation of field trash between them. The runner extends rearwardly from beneath the press wheel and is transversely guided on the supporting vehicle frame of the drill to maintain it in longitudinal alignment within an open longitudinal slot cut through the soil and intersecting the base of the packed furrow. Seed is dropped into the open slot prior to being covered with soil. Moist soil can be packed along the sides of the furrow to maintain the furrow in an open condition during seed germination and plant emergence. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.

    Abstract: The zone tiller attachment employs a pair of spoked tillage wheels that converge downwardly and forwardly toward one another in leading relationship to the planter and in such an orientation that their heavy, thick, blunt spokes mutually intersect and overlap one another along the lower front extremity and bottom portion of the tiller. The crossed spokes penetrate into the soil to pulverize, cultivate, and substantially disturb the soil particles in place with a churning action while also displacing surface residue to opposite sides of the path of travel, thus producing a relatively narrow band of thoroughly tilled soil having a depth extending down to or below the seed planting level such that the trailing opener can perform its trench opening and seed placement functions in the optimum manner.

    Abstract: A planter includes a pair of toothed wheels which sweep mulch away from the path followed by furrow opening discs. The sweeper wheels are carried on the trailing end of a parallel bar linkage attached to a tool bar by which the planter is pulled. As a result of the parallel bar linkage, the sweeper wheels may float upwardly and downwardly independently of the planter frame in order to conform to uneven ground. A spring acts on the parallel bar linkage and may be adjusted either to press the wheels downwardly into the ground if the mulch is hard and dense or to urge the wheels upwardly and relieve some of the weight of the wheels from the ground if the mulch is loose and the underlying soil is relatively fine.

    Abstract: The ridge preparation tool is adapted to be attached to a seed planter directly ahead of the trench-forming structure of the planter so as to skim off the crest of the ridge for the production of a clean, relatively narrow strip of prepared soil in which the trench-forming structure can operate effectively. The free-wheeling skimming disc of the tool is held at an oblique angle to the centerline of the planter and may be adjusted to increase or decrease the extent of side throw of the skimmed off materials by selectively raising or lowering an outwardly bent mounting arm that holds disc at its oblique angle. Raising or lowering the angled mounting arm causes the disc to cock inwardly or outwardly while maintaining the same oblique angle. The throw-adjusted disc can be returned to the same skimming depth by appropriate manipulation of a vertical adjustment unit associated with the tool.
