Spreader for seed or solid material - has switch mechanism with free wheel having arm and eccentrically positioned disc

摘要

The hopper is positioned on the chassis (1) supported on land-wheels (3). Metering-wheels convey the material into pipes extending across the direction of travel and connected by air-ducts to a fan. In front of outlets in the pipes are baffles. A switch mechanism incorporates a plate joined to the chain-drive (13). The switch mechanism has a free-wheel on which is an arm held by a spring on the casing of disc. A cable on the arm leads over a roller to the driver's cab. Eccentricity of the disc switch plate mounting is set by a clamping device.
