The spreader distributes particulate material by a rotating plate which when operating, always impacts material on the deflector. The deflector and a mounting track prevent dispensing material impacting on a user of the spreader, and when the deflector is extended, also prevent dispensing material distributing to the right side of the spreader. In this way, lawns which abut a driveway or a flowerbed may have material distributed on them without also depositing material on the driveway or flowerbed. Further, the deflector is integral with a port closure panel which automatically reduces, in a proportional manner, the flow of particulate material as the deflector is extended.

    Abstract: An agricultural spreader comprises distribution members (11, 12) which rotate to eject material such as fertilizer. The spreader can tilt to one side or the other so as to reduce the spreading distance on one side. This facility enables the spreader to be driven on a field along the same tracks as other agricultural machinery while avoiding waste of material at the edges of fields. Other embodiments utilize braking members which are movable into the path of ejected material to reduce its kinetic energy and consequently its spreading distance.

  • Patent number: 4684068
    Abstract: The crop material or straw discharged from the rear of a combine is spread by a pair of counterrotating spreaders which are vertically and laterally offset from one another and are operative to evenly spread the crop material over a header cut of substantial width. The speed of rotation of the spreaders can be adjusted to change the width of spread. The spreaders can also be adjusted to make them more or less aggressive in throw of discharged crop material. The bottom spreader uses a disc and blades to facilitate catching and spreading discharged material.

  • Patent number: 4681265
    Abstract: A material-directing chute is slidably mounted on a hopper and is interposed between a discharge port in the hopper and a rotary impeller. The position of the chute is controlled by a handle-mounted lever. By shifting the chute to a relatively advanced position, a peripheral portion of a material-receiving drop area on the impeller is shifted radially inwardly from the peripheral edge of the impeller. Accordingly, a material distribution pattern may be provided which avoids areas such as gardens, shrubbery and driveways on one lateral side of the spreader. In addition, a chute-activated damper is provided to impede the flow of material when the chute is in the relatively advanced position.

  • Patent number: 4609153
    Abstract: Distribution members of a spreading device are disposed closely adjacent to each other. The distance between the points of closest approach of the distribution members being about two centimeters with the outside diameter of each distribution member being about thirty-five centimeters. Flow of material to each distribution member of the spreading device is controlled by a delivery member which comprises dosing plates that are independently displaceable relatively to each other and to the bottom of the device's hopper. The dosing plates and the hopper's bottom have openings which cooperate with one another in an adjustable manner which makes it possible to adjust independently the position of the delivery of material to the distribution member both in radial and circumferential directions, and to adjust the size of the openings.
