Upstanding wall I‘! carries a standard 50 which
extends upwardly and to the right as seen in Fig.
1, to a point, partially over above mentioned
opening D. At this point a ?tting 5| provides a
or other means attached to draw bar 23, the rota

units as described, whereupon material is cut by
cutter bar 0, laid on conveyor 44 by reel R and
conveyed by conveyor 44 into opening D, thus

conveyor 44 as shown in Fig. 1. A roller 14, in
the present instance of angular cross section, is

is driven by a short belt 11 from a pulley 18, in
the present instance immediately behind above
mentioned pulley 48 on shaft 41. Roller 14
catches material being discharged from conveyor
44 and assists in guiding it into opening D. In
this manner any tendency for material to follow
