A milling piece, in the form of a generally helical and spiralling vertical feed auger 5, is disposed within bin 2 for milling stockfeed 3. A tapered outlet 7 at the base of bin 2 directs the milled stockfeed 8 from auger 5. A drive train, in the form of a driven input shaft 9 for coupling to a PTO drive, and an associated transmission 10, transfer drive to auger 5. Auger 5 includes a central generally cylindrical hollow steel axle 11 that extends substantially vertically along an axis 12, and a continuous spiralling helical steel flighting 13 that extends axially along and radially outwardly from axle 11. The axle and flighting are, in use, driven via shaft 9 and transmission 10 to rotate counter clockwise. Fighting 13 supports three spaced apart like knives 15 that extend radially outwardly from the flighting. Knife 15 includes a mounting element, in the form of a generally straight steel mounting plate 21, which extends radially outwardly from auger 5. A blade 22 is removably mounted to plate 21, and has two cutting edges 23 and 24 that are formed from a metal with a hardness of at least HRC 55. A fastening element, in the form of a generally straight steel fastening plate 25, releasably and clampingly secures blade 22 to plate 21 to operatively expose cutting edge 23.1/7 288 282 Figur 1
