Fully tapered rotor nose and threshing section

摘要

A threshing and separating mechanism (24) for a combine (10) includes an elongated rotor (37) mounted for rotation about a rotor axis on the combine within a rotor housing (36). The rotor (37) has a threshing portion (38) and a separating portion (39). The rotor (37) has a rotor tube (100) that is tapered continuously in the threshing portion (38) and has threshing elements (122) extending from the rotor tube (100).
