Abstract
A dispenser apparatus for spreading granular material such as salt or sand. The dispenser apparatus includes a hopper that funnels the granular material down to a discharge spout for discharge onto a rotating spreader to broadcast the material onto a roadway. The hopper defines a generally downwardly converging chute that has intermittent radially enlarged sections to minimize 'bridging' of the granular material within the hopper. An agitator arrangement provided in the hopper also assists in eliminating any blockage near the base of the hopper.
