A rectangular baler including a bale chamber having a plurality of walls including a movable wall section, an actuator for exerting a pressure on the movable wall section, a plunger for compressing crop material, and a control system configured to control the plunger to perform cyclic plunger strokes such that in each stroke the plunger force (F) exerted by the plunger on the crop material increases to reach a maximum plunger force (Fmax) to compress a newly inserted slice of crop material. The control system includes a first module to measure, at consecutive moments during a plunger stroke, a plurality of first values for the plunger force exerted by the plunger and/or for the pressure (Pd) in the actuator; and a control module to control at least one baling setting influencing the compressing of the crop material in the bale chamber as a function of the plurality of first values.

A bale chamber includes: movable density doors; at least one fluid cylinder including a fluid chamber, a piston separating the fluid chamber into a piston side and a rod side, a cylinder rod coupled to the piston on the rod side and configured to move at least one of the density doors, a piston fluid port, and a rod fluid port; and a fluid supply circuit fluidly coupled to the fluid chamber and configured to supply working fluid to the fluid chamber, the fluid supply circuit including a fluid supply controller that is selectively switchable to a first fluid supply mode and a second fluid supply mode, the fluid supply circuit being configured to supply working fluid to only the piston side when in the first fluid supply mode and to supply working fluid to both the piston side and the rod side when in the second fluid supply mode.

An agricultural baling machine including: frame; a connection point for attaching to a towing vehicle; a plunger in a bale-forming chamber; a driveline for taking power from the towing vehicle and causing reciprocal rectilinear motion of the plunger in the bale-forming chamber; and a drawbar assembly that provides a mechanical link between the connection point and the frame. The drawbar assembly includes: a lower drawbar member and an upper drawbar member, wherein both members extend in a longitudinal direction of the baling machine from the frame towards the connection point; and wherein the lower drawbar member is spaced apart from the upper drawbar member in a vertical dimension such that one or more components of the driveline are accessible from the side of the baling machine through the drawbar assembly.

An agricultural baling machine including: a frame; a connection point for attaching to a towing vehicle; a plunger in a bale-forming chamber; a driveline for taking power from the towing vehicle and causing reciprocal rectilinear motion of the plunger in the bale-forming chamber, wherein the driveline includes a transmission; and a drawbar assembly that provides a mechanical link between the connection point and the frame. The drawbar assembly includes a transmission mounting member that provides a mechanical connection between the transmission and the frame.

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.

A mounting for a baling machine gearbox includes a first, cylindrical support member secured to and extending from at least a first part of a rigid frame inside the baling machine and a second support member secured to and extending from at least a further part of the rigid frame that in use is spaced vertically from the first part of the rigid frame. The gearbox includes at least one selectively tightenable and loosenable clamp that encircles the first support member and the mounting includes at least one releasable connection securing the gearbox to the second support member, whereby on disconnecting of an input rotary shaft and a crank from the gearbox, and disconnecting of the releasable connection and loosening of the clamp the gearbox is rotatable from the operational position to an access position permitting access to the plunger while supported on the first support member.
