Abstract
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.
