Abstract: Feedstuff is compacted in a tube which lies on the ground by a mobile device which includes a traction vehicle, a trailer unit, and a rotatable feeding screw mounted at the rear of the trailer unit for feeding feedstuff from a container into the tube where it is compacted. The screw is rotated by a hydraulic motor which is driven by hydraulic fluid at a pressure which is proportional to loading of the feeding screw due to compaction of feedstuff by the screw. A brake system brakes the wheels of the trailer unit to produce a braking force while the feedstuff is being fed into the tube. A control unit controls the brake system in response to signals from a transducer which senses the hydraulic pressure at the motor. The braking force is reduced when the sensed hydraulic pressure rises to a predetermined maximum value, and the braking force is increased when the sensed hydraulic pressure decreases to a predetermined minimum value.
