2142116 9403043 PCTABS00030 The specification discloses an agricultural machine (2) for cutting long stemmed animal feed material such as hay and comprises a cylindrical cutting drum (4) mounted for rotation about a substantially horizontal axis (6). A plurality of cutting blades (8) project radially outwards from the circumferential surface (10) of the drum (4). The machine (2) also includes a moveable bed (14) on which, in use, lies the material to be cut. The bed (14) can turn about a horizontal pivot axis (16) adjacent the drum (4). Hydraulic cylinders (18) connected between a frame (20) of a support for the machine (2) and the bed (14) are provided to turn and hold the bed (14) at different angles about the pivot axis (16). The bed (14) includes first, second and third adjacent flat sections (22, 24 and 26) arranged in a U-like configuration. The hydraulic cylinders (18) are used to control the elevation of the bed (14) and therefore the rate of feeding of the material to be cut to the cutter drum (4). A shutter arrangement (42) is located beneath the drum cutter (4) to control the length of time that the material is in contact with the cutting blades.
