  • Patent number: 8176797
    Abstract: A system and method are provided for quantifying a degree of discontinuity of material flow from a meter roller. In an exemplary embodiment, flowable particulate material is fed into a meter roller. The meter roller is then rotated one revolution, and the output from the meter roller is collected and measured. Next, the meter roller is rotated one revolution in discrete increments, each increment having a substantially equal rotational angle. The output from the meter roller is then collected and measured for each increment. Finally, the measurement for each increment is compared to the measurement for the one revolution to determine a statistical parameter indicative of flow rate discontinuity.

  • Patent number: 8087471
    Abstract: An agricultural implement includes a framework configured to be towed behind a vehicle, and a plurality of shanks mounted to the framework and configured to engage the soil. A tillage point is mounted on each shank. Each shank tillage point includes a body having a top surface and a nose extending from the top surface. The tillage point also includes two wings each disposed on a lateral side of the body and extending laterally outward. In certain embodiments, a slope of the nose relative to a horizontal plane of movement of the tillage point through soil is greater than a slope of the top surface of the body. In further embodiments, the wings are configured to engage the soil at a shallower depth than the nose, and/or a tip of each wing is configured to engage the soil at a greater depth than a respective wing root. In yet further embodiments, the tillage point includes a boss positioned forward of openings configured to receive a fastener for coupling the tillage point to a shank.

  • Publication number: 20110284252
    Abstract: In an embodiment, an agricultural implement includes a tool bar and a tool frame rotatably coupled to the tool bar. The agricultural implement also includes multiple row units coupled to the tool frame, and a frame actuator extending between the tool bar and the tool frame. The frame actuator is configured to rotate the tool frame between a lowered position that places each row unit in contact with soil and a transport position that raises each row unit above the soil. The frame actuator is also configured to transfer weight from the tool bar to the tool frame while the tool frame is in the lowered position. Each row unit includes a ground engaging tool configured to selectively engage and disengage the soil while the tool frame is in the lowered position.

  • Publication number: 20110272939
    Abstract: In an embodiment, a hose coupling assembly includes a collet including a head and an axial protrusion extending from the head in a first axial direction. The axial protrusion is configured to engage a hose while the axial protrusion is in a locked position, and to disengage the hose while the axial protrusion is in an unlocked position. The hose coupling assembly also includes a housing disposed about the axial protrusion and configured to receive the hose. An inner surface of the housing is shaped to enable movement of the axial protrusion toward the unlocked position in response to movement of the axial protrusion in the first axial direction, and to drive the axial protrusion toward the locked position in response to movement of the axial protrusion in a second axial direction, opposite the first axial direction.

  • Patent number: 8033230
    Abstract: The present invention provides a method and apparatus to improve seed distribution to a plurality of seed or row units of an agricultural planter. Each row unit is fitted with a seed box having an air/seed inlet and an air outlet through which air is allowed to escape. The present invention effectively closes off or substantially reduces the flow of air out of one or more of the seed boxes to reduce the amount of seed that is fed to the seed boxes. Through the use of restrictor plates, which may be vented to allow some air flow or solid to prevent air flow, the delivery of seed to the seed boxes can be equalized to provide more uniform seed distribution to the row units.
