Abstract
An agricultural baler includes a main bale chamber extending in a bale forming direction from an inlet end to an outlet end. The main bale chamber includes a plurality of stationary walls and a plurality of movable density doors positioned downstream from the stationary walls, relative to the bale forming direction. The stationary walls include a ceiling, a first side wall and a second side wall. A plunger compresses and moves the crop material from the inlet end towards the outlet end of the bale chamber. The baler is characterized in that the first side wall, the second side wall and/or the ceiling comprises a constriction surface, which constricts the main bale chamber in a direction transverse to the bale forming direction.
