<p>A cutting pusher (2) of a silage remover (7) comprises, at its lower edge, blades (17) movable to and fro and, facing a lateral wall (21), a rotary cutting disc (18). A crown (32) fastened by means of screws (33) has a lip (32a) engaged in a groove (31) of the disc (18) to form a labyrinth gland. The crown bears elastically on the disc by means of an anti-friction packing (34). A shaped piece (36) masks the toothing of the disc above the ends (17a) of the blades (17) and supports said ends by means of a beak (36g). The invention is used to prevent the clogging of material introduced between the disc and the wall (21) as a result of the rotation of the disc and as a result of the penetrating movement of the cutting pusher into the silage material, and to guide the bottom of the disc and the end of the blades. <IMAGE></p> |
