An apparatus comprising a pair of associated chopper drums, including a top chopper drum and a lower chopper drum. The chopper drum defines an axial cylindrical bore having a rotational axis into which is mounted a drive shaft (not shown) that is keyed radially to drive the chopper drum. Radially spaced from the rotational axis are a plurality of outwardly facing recesses defined by walls of a body of the chopper drum. Each recess extends longitudinally along the periphery of the chopper drum end-end to provide a recess for mounting a corresponding plurality of cutting blades. Each recess is defined by a longitudinally extending lower wall and an opposed and circumferentially spaced. The cross sectional profile of the chopper drum is generally consistent throughout its length and includes a plurality of ridges and troughs with the ridges built up to define therein the recesses, the ridges being interposed by the troughs. A higher side wall provides support for the cutting blade and is inclined relative to a plane extending radially outwardly from the rotational axis. The opposed smaller side wall supports a wedge clamp.

An apparatus (10) comprising a pair of associated chopper drums (20), including a top chopper drum (21) and a lower chopper drum (22). The chopper drum (20) defines an axial cylindrical bore (25) having a rotational axis (26) into which is mounted a drive shaft (not shown) that is keyed radially to drive the chopper drum (20). Radially spaced from the rotational axis (26) are a plurality of outwardly facing recesses (30) defined by walls of a body of the chopper drum (20). Each recess (30) extends longitudinally along the periphery of the chopper drum end-end to provide a recess for mounting a corresponding plurality of cutting blades (35). Each recess is defined by a longitudinally extending lower wall (31) and an opposed and circumferentially spaced. The cross sectional profile of the chopper drum (20) is generally consistent throughout its length and includes a plurality of ridges (26) and troughs (27) with the ridges (26) built up to define therein the recesses 30, the ridges (24) being interposed by the troughs (27). A higher side wall (32) provides support for the cutting blade (35) and is inclined relative to a plane (36) extending radially outwardly from the rotational axis (26). The opposed smaller side wall (31) supports a wedge clamp (40).
