Abstract
An improved feed distribution and closure mechanism for use with broadcast spreaders for spreading granular or powdery material or both is described. The mechanism comprises a threaded shaft, a disk mounted on the shaft having a central opening provided with internal threads mating with the shaft, a return spring, and a collar or the like on the shaft to stop travel of the disk on the shaft. Materials which may be spread using spreaders equipped with the mechanism include, without limitation, sand and/or salt on roads; materials such as herbicides, pesticides, fertilizer, lime and seeds such as grass seed on fields, lawns, golf courses and the like; and most particularly, feed for both domesticated and game animals and birds.
