Modular system for manure spreaders of limited spread

摘要

The modular system may include a limit setter disc (16) or blades or adjustable blades for border spreading over the full working width or again should be fitted with a device (9) to tilt the spreader (1) round an axis in the line of travel. A limit spreader screen can also be optionally added for a half-width spread and again a screen for the full working width. The tilting device is mounted on the spreader frame (3) for this border limit spreading operation or one of the spreader discs can be replaced by a limit spread disc. In operation, the spreader scatters manure within limits by its conventional spreader discs (4), overlapping these spreading areas to give field coverage. Limit or border spreading is achieved by the device which also provides for a steep reduction in spread density at the boundary ditches etc. Tilting involves the cylinder-powered swing lever (15) to tilt the spreader enough to afford total field cover.
