ABSTRACT:
A hopper and feed wheel assembly for a fertilizer or pesticide spreader is described. This assembly includes an open topped storage bin or hopper having a concave or "V"-shaped bottom with a flat center plat being disposed along the center or lower most point of the base, the center plate being movable according to calibrated settings to provide a gate opening for discharge of fertilizer or pesticide. To facilitate continuous discharge of fertilizer or pesticide out of the bottom gate opening with minimal break up of particles or clogging of the gate opening, the hopper is further equipped with a feed wheel made up of a rotatable shaft traversing the width of the bin and having its longitudinal axis directly above and parallel to the length of the center plate, the shaft being affixed to a longer smaller diameter rod which is attached to the shaft at its ends and extends outward from the peripheral surface of the shaft at the points of attachment and is bent back in a direction parallel to the longitudinal axis of the shaft in a series of rod lengths which substantially traverse the length of the shaft, each rod length being joined to another by a series of reverse bends extending substantially around the periphery of the shaft.
