Abstract:
A straw chopper for a combine includes a rotor mounted in a housing with blades on a rotor for chopping the discharge material onto a material spreading assembly. The rotor is driven by a drive transmission from an output drive shaft of the drive system of the combine harvester including first a right angle gear box connected to the drive shaft, a second right angle gear box connected to the rotor and a single drive shaft communicating drive from the first gear box to the second gear box. One end of the rotor is supported by a shaft of the second gearbox carried on the combine housing. An adjustment is provided at the output shaft or at a gearbox to remotely from the cab adjust the speed of the rotor. The drive transmission includes a cogged timing belt for positive drive for increased power.

Claim (Index 21):
A method for discharging straw from a combine harvester including a crop inlet system at a front of the combine harvester for collecting a crop to be harvested as the combine harvester moves in a working direction, a threshing system for separating the crop into grain and a discharge material including at least straw and a rear discharge for expelling the discharge material from the combine harvester, the method comprising:\n mounting a chopper assembly mounted at the rear discharge comprising a housing and a chopping rotor mounted in the housing for rotation around an axis transverse to the working direction and carrying a plurality of chopper blades extending outwardly from the axis and cooperating with stationary blades on the housing for chopping the discharge material as the rotor rotates around the axis; directing the chopped discharge material from the chopping assembly onto a tailboard extending rearwardly from the chopping rotor in response to rotation of the rotor as the rotor rotates; the tailboard having a plurality of guide fins on an underside thereof for spreading the chopped discharge material across a spread width to the rear and sides of the combine harvester; and varying the spread width of the chopped discharge material by providing a continuously variable drive component operable to vary the rotational speed of the chopping rotor so as to adjust a velocity of the chopped material discharged onto the tailboard and thus the spreading of the material to the rear and sides of the combine harvester.
