  • Publication number: 20210307229
    Abstract: A control system for controlling an implement that is movable between a work mode and a transport mode. The control system includes a source of hydraulic fluid, a first actuator and a second actuator. The first and second actuators are fluidly coupled to the source and disposed parallel to one another. A sensor detects movement of the first and second actuators between their retracted and fully extended positions, and a control valve is disposed in communication with the sensor and in fluid communication with the first and second actuators. As the implement moves to its transport mode, the sensor detects movement of the first and second actuators towards their fully extended positions. The control valve inhibits movement of the first and second actuators before either actuator reaches its fully extended position.

  • Patent number: 11064649
    Abstract: A seeding machine for a row unit, in which the row unit has a seed disk rotatable about a first axis to convey seed from a seed reservoir, includes a seed delivery apparatus. The seed delivery apparatus includes an elongated housing having a first opening through which seed is received, a second opening through which seed exits, and an elongated interior chamber. The seed delivery apparatus further includes a first pulley, a second pulley, and an endless member driven by the first pulley and/or the second pulley. The endless member is movable within the elongated interior chamber to receive seed from the first opening and convey seed to the second opening. A seed diverter is movable with respect to the endless member and pivotable about a second axis non-coincident with the first axis. The seed diverter is positioned to contact and guide seed into the seed delivery apparatus.

  • Publication number: 20210204466
    Abstract: A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

  • Publication number: 20210076558
    Abstract: A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short crop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture move and accelerate the seed By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

  • Patent number: RE48572
    Abstract: A planting unit for a seeding machine having a seed meter with a metering member that moves seed sequentially along a first path to a release position at which the seed is moving in a first direction and a delivery system adapted to take seed from the metering member at the release position and control movement of the seed from the seed meter to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine. The delivery system, at the release position, moves seed in a second direction along a second path. A blocking member located adjacent the first path immediately preceding the release position prevents movement of the seed in the second direction until the seed has passed the blocking member.
