ABSTRACT:
A material spreader includes a hopper having an opening in its bottom through which material flows to a rotatable fan, which is driven from one of a pair of support wheels for the hopper during pushing or pulling of the spreader across the ground, for spreading the material. A gate, which is pivotal about the same axis as the axis about which the fan rotates, has an opening, which is smaller than the opening in the hopper, to control the portion of the opening in the hopper through which the material flows to control the spread pattern produced by rotation of the fan. A shutter, which is disposed beneath the gate, has an opening, which is smaller than the opening in the gate, cooperating with the opening in the gate to control the rate of flow from the hopper. The gate has a first arcuate slot therein within which is disposed a bolt supported by the hopper to limit pivoting of the gate. A wing nut cooperates with the bolt to lock the gate in the desired position without affecting movement of the shutter. A second arcuate slot in the gate has a bolt, which is supported by the gate, disposed therein with a wing nut cooperating with the bolt to lock a bushing on the bolt in engagement with the shutter to hold the shutter in its desired position while also preventing inadvertent movement of the shutter beyond its desired position.
