PCT No. PCT/GB88/00060 Sec. 371 Date Aug. 7, 1989 Sec. 102(e) Date Aug. 7, 1989 PCT Filed Feb. 1, 1988 PCT Pub. No. WO88/05626 PCT Pub. Date Aug. 11, 1988.The apparatus for harvesting crops, particularly seed crops, comprises a mobile support structure (20) and a crop stripping device in the form of a rotor (30), which may be attached to height adjustable arms and is driven by drive means (22). The rotor (30) carries transverse rows of crop stripping elements (1) which may be combined with transverse ribs. The crop stripping elements have prominent leading edges, for example each formed at the junction between two faces which are acutely inclined with respect to each other. The drive to the rotor is so arranged that during forward movement of the apparatus the crop engaging elements (32) are propelled progressively through the crop, moving upwards at the front region. Seeds and other plant parts detached by the action of the rotor are impelled into a crop flow passage (27) under a crop guide cover (21). A transverse auger (83) transfers the detached material into a duct (84) where an elevator (85) moves it over a screen (86) for separation of the seeds.
