  • Patent number: 7938073
    Abstract: An air seed meter having a rotating disc with seed openings arranged in a circumferential pattern includes a holder adapted to be mounted to the meter housing and carries two balls spring-biased to reciprocate and enter the seed openings as they pass and clear debris from the openings. The balls may also engage dimples on the seed disc located between seed openings or groups of seed openings (in the case of a hill drop planter) in the disc as it rotates to cause vibration in the disc to promote the release of seeds as they exit the vacuum chamber.

  • Patent number: 7818954
    Abstract: A method and apparatus for baling a crop with stiff stalks such as corn stalks has a frame with a front and a rear. At least one ground engaging wheel operatively attached to the frame for facilitating movement of the frame in a forward direction. An accumulator is operatively attached to the frame for holding the crop in various amounts. A pickup is operatively attached to the front of the frame for picking up the crop from a field and transferring the crop into the accumulator. A baler is operatively attached to the frame behind the accumulator for transforming a crop into a bale. A transfer mechanism such as a conveyor is provided in the accumulator for moving the crop in the accumulator to the inlet of the baler. In another embodiment, a pickup of a first predetermined width is provided for picking up the crop from a field and transferring the crop into the accumulator.

  • Publication number: 20100037577
    Abstract: An oversleeve for preventing crop material from wrapping around an agricultural implement shaft. The oversleeve is disposed over the implement shaft and affixed to a stripper pan so it does not rotate with the shaft. The oversleeve is preferably made of a polymer composite material. Removal of dirt between the shaft and oversleeve is effected by a helical groove arranged so the dirt is driven to the ends of the oversleeve.

  • Publication number: 20090100814
    Abstract: A non-powered rotor windguard improves the baling of stiff crop material such as cornstalks. The windguard comprises plastic teeth spaced evenly along a rotatable shaft. The teeth are generally three-pointed. The engagement of the teeth to the crop material provides the force to rotate the roller windguard.

  • Patent number: 7152542
    Abstract: An air seed meter for an agricultural planter includes a vacuum cover which has a central opening which exposes the central portion of the seed disc to the exterior. The central opening of the vacuum cover is centered on a location offset from the axis of rotation of the seed disc. This reduces disc wear at the disc-vacuum cover interface, and renders the disc more accessible for self-cleaning, visual inspection and verification of the proper disc. Openings in the central, open portion of the disc, the back wall of the seed housing and the side wall of the seed housing cooperate to equalize the air pressure in the seed reservoir to atmospheric pressure and reduce or eliminate reverse air currents in the discharge chute. An adjustable brush with three separate stations cooperates with an edge-release, beveled disc to apply a progressively more forceful singulation force to eliminate duplicate seeds.

  • Publication number: 20040184905
    Abstract: An agricultural grain wagon includes a one-piece floor auger which may be removed as a unit from the rear of the wagon for servicing. A clean-out pan is slidably mounted beneath the floor auger and a lower tough forming the bottom of the hopper. The clean-out pan may be reciprocated beneath the floor auger to clean out any residual grain beneath the hopper. The wagon also includes a forward two-piece unload auger having an upper section which may be positioned to a field fold position using an auger stand, thus reducing the time to place the unload auger in the discharge position and providing an extended reach of the unloaded auger to facilitate unloading.

  • Patent number: 6776108
    Abstract: A planter apparatus includes a seed meter including a housing assembly with a cover releasably connected to a shell. The housing assembly includes at least one opening formed therein adjacent a seed discharge area to promote the release of seeds from a disc rotatably attached to the housing assembly. The disc divides an interior of the housing assembly to include a vacuum chamber and a seed chamber. The disc including a plurality of openings formed adjacent a periphery of the disc. The planter apparatus may also include a singulator assembly having rotatably spools, a rotatable chute door, a disc having clusters of openings for simultaneous release, and a one-piece baffle.
