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.

Bale chamber arrangement for an agricultural baler

An agricultural baler includes a hydraulic circuit with a first hydraulic cylinder connected between the first end of the first axle and the chassis, and a second hydraulic cylinder connected between the second end of the first axle and the chassis. At least one sensor senses a position of the chassis relative to the first axle. An electrical processing circuit is coupled with the hydraulic circuit and the at least one sensor. The electrical processing circuit controls operation of the hydraulic circuit, and includes an operator input device for selectively: 1) raising the chassis of the baler relative to the first axle, 2) lowering the chassis of the baler relative to the first axle, or 3) automatically returning the chassis of the baler to a predetermined operating height relative to the first axle, dependent upon an output signal from the at least one sensor.

Needle coupling device for an agricultural baler

An agricultural baler has a bale chamber for the compression of crop into bales with a floor, ceiling, and two walls. A plunger forces crop into the bale chamber. An actuator system presses the ceiling and walls of the bale chamber inward. At least one retractable friction block in the ceiling or walls is used to increase the compression and density of the crop. The friction blocks extend inwards as an increasing function of either decreased pressure being exerted against the ceiling or walls by the crop being baled, or inward displacement of the ceiling or walls by the actuator system.
