<p>In apparatus for conveying and treating crop a horizontal rotor (11) collects crop and conveys it upwardly and rearwardly over the rotor beneath a hood (15) extending at least around part of the front half of the rotor (11) and forming with the rotor a crop flow passage. The rotor (11) comprises outwardly extending crop engaging elements (10), preferably flat transverse ribs (23) extending across the rotor, the crop engaging element (10) having a principal plane which traverses the general direction of crop flow. A stationary crop retarding device (9) forms the intake of the crop flow passage and co-operates with the rotor to effect conditioning or other treatment of crop. The crop retarding device is positioned at the intake region of the crop flow passage, and comprises an array of projections (17) which can be adjusted to project to a greater or lesser extent into the crop flow region, and at the position of maximum intrusion, the projections (17) intermesh with the elements (10) on the rotor without contact between the projections (17) and the crop engaging elements (10) of the rotor.</p> |
