Abstract
A grain spreader is provided with a plurality of rigid mounting arms each of which is supported in a pivotal manner at the periphery of a bin top opening and at the spreader body, with each arm extending to the main spreader body along a chord of the opening, for ready adjustability to openings of different effective diameters. The thrower plate is pivotally supported on a link which is joined to a hollow rotatable vertical shaft and on a coaxial vertical rod which extends upward through the shaft. The rod is adjusted axially of the shaft for changing the angle of the thrower plate relative to the horizontal, and the shaft, rod, link and thrower are rotatable as a unit in any position of relative adjustment. A distributor plate mounted on the upper end of the rod and shaft is provided with radial vanes for distributing the grain within the receiving guide to maintain even flow.
