Axial flow combine harvester with adaptable threshing unit.

摘要

An axial flow combine harvester is described which comprises rotor having a thresher section (57) and a separator section (58). The thresher section (57) includes pairs of rasp bars (60,61) staggered from one another along a helical path and individual rasp bars (61) of at least the pairs of rasp bars adjoining the separator section (58) of the rotor are removable to render the action of the thresher section less aggressive. To reduce the risk of plugging when a trailing rasp bar is removed a flow deflector plate (120) is mounted in its place to guide the crop flow continuously from the remaining rasp bar (60) to the infeed end of the separator section (58). <IMAGE>
