  • Publication number: 20150216111
    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 drop 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.

  • Publication number: 20150201550
    Abstract: A seeding machine with a seed meter and a seed delivery system for moving seed from a seed meter to a furrow formed in the soil. The delivery system has an endless member moving in a housing about pulleys to move seed from an upper opening in the housing to a lower discharge opening. In one embodiment, a loading wheel at the upper opening to the housing engages seed on a metering disk to move seed into the housing. The metering disk and housing can be arranged in planes parallel to one another.

  • Publication number: 20150020721
    Abstract: A planter is described which utilizes individual seed meter motor drives at each row unit. motor controllers control each seed meter drive motor. Each individual row seed meter can be individually started, stopped and operated at a unique rate. Prior to planting, the meters can be operated to fill the meters and ensure that the meters are primed and ready to start dropping seed as soon as the planter begins operation to plant seed. When a seed delivery system is used with each meter to move seed from the meter to the soil, the delivery system is also primed with seed before operation of the planter.

  • Patent number: 8863676
    Abstract: A twin-row planter is shown configured to plant different varieties of seed. Each planting unit of the twin-row is separately controlled to turn on or off the seed meter of the planting unit. This enables operation of only one seed meter of the two planting units in each twin-row. With the planting units supplied with different varieties of seed, the variety being planted can be controlled by controlling the seed meters of the two planting units within the twin-row.

  • Patent number: 8616298
    Abstract: A bushing is provided for mounting a pivot arm that has both a threaded portion as well as one or two smooth cylindrical portions. The threaded portion enables the pivot arm to be a laterally adjusted by rotating the bushing while the smooth portion or portions provide a bearing surface or surfaces for the pivot arm loads. This removes the load from the threads, reducing wear of both the bushing and the pivot arm, thereby reducing maintenance cost.

  • Patent number: 8408149
    Abstract: A ground working machine having a frame, a ground engaging wheel mounted to the frame and movable between a raised position not engaging the ground and a working position engaging the ground. The ground engaging wheel, when in the working position, rotating about a wheel axis as the machine is moved over the ground. An actuator raises and lowers the ground engaging wheels. A control system includes a sensor to detect rotation of the ground engaging wheel and a controller that receives an input from the sensor. The controller commands the actuator to raise the ground engaging wheel when the sensor detects that the ground engaging wheel is not rotating.

  • Publication number: 20130032362
    Abstract: A supplemental down force system for a ground working implement is provided where the supplemental downforce system groups the row units into at least two groups and provides a different supplemental down force to the row units in each group. This enables the row unit to have a supplemental down force closer to the desired down force recognizing that the row units do not all operate in the same conditions. The controller periodically regroups the row units into the at least two groups and readjusts the down force.

  • Patent number: 8074586
    Abstract: A seed delivery apparatus has a moving member that captures and entraps the seed from the seed meter and physically moves the seed from the meter to the lower outlet opening. In so doing, the seed engages and travels along an interior surface of the seed delivery apparatus. A seed sensor is mounted on the housing wall such that the seed passes directly in front of the sensor. The sensor has both the light emitting devices and the photo-sensitive elements on the same wall of the delivery apparatus, or on two opposed walls. The moving member prevents ambient light, dust and dirt from entering the housing and impacting the sensor output signal.
