  • Patent number: 9398739
    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.
    Type: Grant

  • Publication number: 20070234698
    Abstract: A control system for a cutting reel unit includes a height-of-cut adjusting system and a reel-to-bedknife clearance adjusting system. The height-of-cut adjusting system includes a first frame; a second frame; a cutting reel supported by the second frame; a bedknife arranged adjacent to the cutting reel and supported by the second frame; at least one support element arranged to translate along the ground and arranged to support the first frame; and at least one first actuator connected between the first frame and the second frame and arranged to adjust the relative elevation of the second frame with respect to the first frame. The reel-to-bedknife clearance adjusting system includes at least one second actuator operatively connected between the reel and the second frame and a sound detector. DC electric rotary motors assemblies may be used to set the reel-to-bedknife gap and height-of-cut for the reel cutting unit.

The reel-to-bedknife clearance adjusting system includes at least one second actuator operatively connected between the reel and the second frame and a sound detector. Once contact is detected between the reel and bedknife, the adjustment actuators may reverse direction and be energized in a direction that would increase the gap.
