ABSTRACT:
This screw auger chemical applicator is designed to evenly and non-cloggingly feed chemical or small seed onto a ground surface. Primarily, it consists of a pulley and belt train driven by a wheel in engagement with a trailing wheel of a pair of wheels mounted to a towed frame behind a farm tractor, and the pulley and belt train drives a left and right pitched auger beneath each hopper of the applicator, for even feed from a pair of discharge openings in the hopper. A by-pass tube is also provided beneath the auger portion, for preventing compacting of the chemical or seed that could cause malfunction.
