Abstract: A pick-up trailer comprising a feeding mechanism composed of a pick-up (7) and a rotor (4) linking up therewith in downstream direction, and partly surrounded by a guide plate (9), thereby producing a guide channel (10) between the rotor and the guide plate. The guide channel (10), at the end opposite pick-up (7) is bounded in the downward direction by a rotary roller (12) and terminates at the top in a bottom opening of the trailer. The roller (12) as well as shaft (3) are mounted for rotation between side plates (5) attached to the bottom (1) of the trailer. The arrangement is characterized in that the rotary roller (12) is attached to separate, adjustable suspension arms (13) mounted for rotation to the shaft (3) of the rotor.
