ABSTRACT:
A chaff spreader for attachment to a combine includes a pair of spaced circular mounting rings, each having a fan rotatably mounted therein. An elongated drive shaft extends between the fans and is connected to a belt and pulled drive system for rotating the fans. A semi-cylindrical shroud is secured between the mounting rings and partially surrounds the fans. An open side wall portion of the shroud is directed forwardly toward the sieve of the combine for inducting chaff through the fans and laterally outwardly from the combine. The belt and pulley drive system is connected to a pulley on a straw chopper section of the combine. In a second embodiment, a generator driven light is mounted on the combine, adjacent the fans to serve as a warning to indicate fan rotation. The shaft spreader collects chaff through a suction effect created by the fans and spreads chaff evenly across the width of the cut, eliminating the toxic effect to seedlings growing through a concentration of chaff residue.
