Abstract

A combine has a cutting mechanism (12) for cutting a crop and a feed mechanism (13) for feeding the cut crop towards a threshing and/or separating rotor (21) which rotates within a housing (20) about an axis disposed generally longitudinally relative to the combine, the cut crop moving between the rotor and the housing from an inlet end of the housing towards an outlet end of the housing across a grating (22) through which separated grain leaves the housing. The harvested crop is fed by a final feed section (18) of the feed mechanism into the inlet end (20a) of the housing across a transition edge (A-A, B-B, C-C) of the housing which is split into a number of sections. The overall direction of extension of each section (A-A, B-B, C-C) of the transition edge is inclined at substantially the same angle with respect to the axis of rotation of the rotor so that the crop entering the inlet end of the housing across the transition edge does so generally perpendicular to the transition edge, the transition edge being inclined generally helically relative to the axis of rotation of the rotor.
