ABSTRACT:
An apparatus for spreading granular material having a pre-calibrated material gauge removably located in the bottom of a hopper. The granular material is forcibly pressed through discharge apertures formed in the material gauge under the rotatory action of an auger mounted in the hopper. The discharge apertures are sized to inhibit the free flow of granular material therethrough when the auger is not rotating. A clutch mechanism is provided for permitting selective control of the rotary movement of the auger. Since the material gauge is interchangeable, the apparatus can be quickly converted for spreading a variety of differently sized granular materials.
