  • 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.

  • Publication number: 20110232554
    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: 20090115222
    Abstract: A cargo box for a utility vehicle has a metal floor and composite polymer side panels. The side panels may be fastened to the floor such that relative movement may occur. Stiffening members resist rearward movement of the side panels that could result in a gap between the cargo box and tail gate.

  • Patent number: 6752095
    Abstract: A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed metering system includes a seed disc having a plurality of spaced apart seed cells and a circumferential edge. An edge drive engages the circumferential edge for rotatably driving the seed disc. Each seed placement system is in communication with a corresponding seed metering system.

  • Patent number: 6651570
    Abstract: A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed placement system includes a seed slide and a wheel. The wheel includes a structural hub, a resilient middle layer positioned radially around the hub, and a gripping outside layer positioned radially around the middle layer. The gripping outside layer has a circumferential periphery which is positioned adjacent to at least part of the seed slide. The circumferential periphery has a plurality of contiguous disc joint surfaces.
