Upstanding wall I‘! carries a standard 50 which
extends upwardly and to the right as seen in Fig.

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
forming a continuous windrow behind the ma
