Abstract
An agricultural baler has a pick-up for picking up crop. The picked up crop is fed rearwardly from the pick-up into a compression chamber in which the crop is compressed into a high density bale by a compression member. The compression member is movable into the compression chamber to act on the crop and is then movable rearwardly when within the compression chamber to compress the crop against a stop to form the bale. The compression member is then movable outwardly of the compression chamber and, while disposed out of the compression chamber, is movable forwardly to return to the original position at the front of the compression chamber.
