Abstract
A material spreader is adapted to dispense granular material from a vehicle. The material spreader includes a feed chute having a discharge opening and a discharge disc assembly disposed below the feed chute. The discharge disc assembly includes a spinner disc adapted to receive granular material from the feed chute, a shroud disposed in at least partial covering relation to the spinner disc, and a rotational drive operatively connected to the spinner disc such that the spinner disc is rotatable within the shroud about a rotational axis. The shroud includes a pass-through opening disposed in substantially aligned relation with the discharge opening of the feed chute at a position radially removed from the central rotational axis. The discharge disc assembly is rotatably mounted in pivoting relation about a pivot axis extending through the pass-through opening and the discharge opening of the feed chute.
