Abstract: A feeder for a field crop chopper is provided which has a stationary mating knife, at least one chopping knife arranged at a cutting angle to the mating knife so as to provide a drawing cut commencing at a given part of the mating knife, and a draw-in device whose feed direction is generally perpendicular to the mating and cutting knives and which is supported directly in front of the mating knife generally parallel thereto. The draw-in device includes at least one draw-in roll which is provided with a transverse feed device which imparts a feed direction component to the material to be chopped which is axial with respect to the at least one draw-in roll and directed towards the part of the mating knife at which the cut of the material commences.

Abstract: A forage harvester (10) with a pick-up device (12) for the material to be chopped, and, connected to a chopping and/or conveying equipment, a delivery tube (16) with a delivery opening (18), possesses a re-comminuting device (32), comprising more than one group (42a-42c) of profiles (34) with gaps (38) positioned in the impact area of the material accelerated or to be accelerated by the chopping and/or conveying equipment in such a way that the gaps (38) of each group (42a-42c) issue at the end of each group (42a-42c) lying approximately in the direction of delivery, and the profiles of the following group (42b-42c) are offset so that the outlets of the gaps (38) each face a profile (34) of the following group (42b-42c).
