An anti-wrapping device is described for preventing crop from being wrapped about the central shaft of a reel rotatably supported on side arms of a header of a combine. The device comprises an annular cover plate for securing to the axial end of the reel to prevent the crop from becoming entangled with projections from the reel and a tubular shroud for mounting on the header support arm to surround the central shaft of the reel, the axial end of the shroud being positioned when in use in close proximity to the annular cover plate of the reel to avoid any crop being caught therebetween.

A crop chopper arrangement generally comprises a discharge apparatus having an inlet adapted to receive chopped crop from a crop chopper for an agricultural machine. The arrangement further includes a row of guide vanes positioned substantially transversely to a longitudinal axis of the agricultural machine and adapted to spread out a flow of the chopped crop from the discharge apparatus in a direction substantially rearwards to a direction of travel of the agricultural machine. One or more of the guide vanes has a shape or configuration that is adapted to impart a predetermined deviation to at least a portion of a flow of chopped crop passing through said discharge apparatus. The shape or configuration of each guide vane is dependent on its transverse position in the row. This arrangement makes it possible to realize an even distribution of the chopped crop over the full width of the harvester header.

Crop chopper arrangements for agricultural machinery

A concave arrangement is disclosed for a threshing machine such as a combine harvester. The arrangement includes a concavehaving a moveable rear portionthat is adapted to vary the break-over angle presented to straw passing downstream. A flap memberis provided that moves jointly with the moveable rear portionand ensures that a gap G between the moveable portionand a later processing stage such as a beater apparatus is kept substantially closed. Variation of the break-over angle influences the length of the straw leaving the threshing machine and the loading of the further separation and cleaning mechanisms.

Threshing machinery concave arrangements

A management system is disclosed for controlling the tension of an endless track by regulating the hydraulic pressure in a hydraulic jack acting on a roller serving to tension the track. The tension management system comprises two accumulators of different capacity that are connected to the jack. Both accumulators are in permanent direct communication with the jack and the larger accumulator is preloaded to a higher pressure than the smaller accumulator.
