Abstract

The thresher-separator unit has a cutter unit at its discharge end including a cutter member carried at the discharge end of the thresher-separator cylinder and provided with at least one radial bracket with a series of blade sections. The cutter unit further includes a casing which surrounds the upper part of the cutter member and is provided internally with at least one series of fixed blade sections located in alternating positions with respect to the blade sections of the cutter member and arranged to cooperate therewith to cut the straw leaving the thresher-separator unit. This unit further includes a spreading reel located below the cutter member and rotatable about a vertical axis to spread the cut straw uniformly on the ground. A bladed roller between the cutter member and the spreading reel is rotatable about an axis parallel to the axis of the thresher-separator cylinder and is arranged to prevent the stoppage of the flow of material and facilitate its discharge from the cutter unit. The cutter-spreader unit can easily be interchanged with a unit for discharging the straw in a window.
