A dual path agricultural machine including a control system having a number of input sensors, status sensors, and output sensors, and a controller configured to operate the dual path machine in a stability control mode and a selective rear-steer engagement and actuation mode. In the stability control mode, the controller adjusts an actual drive output of the dual path machine according to data received from the input sensors and feedback received from the output sensors so as to reduce a difference between the actual drive output and a desired drive output. In selective rear-steer engagement and actuation mode, the controller engages rear-steer mechanisms with caster wheels of the dual path machine and actuates the caster wheels via the rear-steer mechanisms if a criterion is satisfied. The controller disengages the rear-steer mechanisms from the caster wheels or does not actuate the caster wheels if the criterion is not satisfied.

An agricultural mower conditioner includes: a frame including a tongue coupler and defining a frame width; a cutter bar including an odd number of cutting discs arranged side-by-side across a cutter bar width; and a conditioning roll carried behind the cutter bar, the conditioning roll being offset with respect to a centerline that bisects the frame width and the cutter bar width.

A crop conditioning device for an agricultural harvesting machine. The crop conditioning device includes a frame, a first conditioning roll connected to the frame, and a second conditioning roll connected to the frame such that the second conditioning roll is movable relative to the first conditioning roll. The crop conditioning device also includes a tension mechanism connected to the second conditioning roll. The crop conditioning device also includes a roll-gap mechanism connected to the second conditioning roll. The crop conditioning device also includes a controller which is configured for automatically setting at least one of an initial tension force and an initial roll gap dependent upon at least one of a type of crop material and at least one operational setting.

A crop conditioning device for an agricultural harvesting machine. The crop conditioning device includes a frame, a first conditioning roll, and a second conditioning roll. The crop conditioning device also includes a tension member operably connected to the second conditioning roll. The tension member is configured for applying a tension force on the second conditioning roll. The crop conditioning device also includes a tension actuator operably connected to the tension member. The tension actuator is configured for adjusting the tension force applied by the tension member. The crop conditioning device also includes a pair of control rods respectively connected to the pair of lateral ends of the second conditioning roll. The crop conditioning device also includes a pair of roll-gap actuators respectively and operably connected to the pair of control rods. The pair of roll-gap actuators are configured for pivoting the second conditioning roll to adjust the roll gap.

A cracker roller disc has a first portion radially outward of the centre of substantially constant thickness, and a second portion radially outward of the first portion which second portion tapers towards the periphery of the disc. A plurality of upstanding ridges extending radially outward across the second portion on opposed faces of the disc are machined to define respective conical surfaces forming radially extending edges on opposed faces of the disc. The disc is provided with one or more circular or spiral grooves which cut across the edges in a substantially perpendicular direction to the edges. The grooves extend the effective length of each edge.

The present invention relates to the general technical field of agricultural machinery. It concerns an agricultural device, in particular a haymaking device, which can be moved in a direction of advance and which includes a cutter bar equipped with cutting elements intended to cut a standing crop product. The device also comprises a conditioner positioned behind the bar, and a grouping device intended to move the product transversely to the direction of advance and located behind the bar, in an active position. A retraction actuator is configured to transpose the grouping device between the active position and a passive position in which the product is deposited at the rear of the device. A collecting device extends partially under and partially behind the conditioner in active position of the grouping device. The invention also concerns an agricultural machine equipped with such a device and a method for access between a conditioner and a grouping device belonging to such a device.

A converging drum for a crop mowing implement includes a body that extends along a central longitudinal axis. The body rotates about the central longitudinal axis in a defined rotational direction. At least one ramp feature extends radially outward from the body, relative to the central longitudinal axis. The ramp feature is arranged to form an acute angle relative to a reference plane. The acute angle may open toward the defined rotational direction to move cut crop downward, or the acute angle may open away from the defined rotational direction to move crop upward, to position the cut crop for a conditioning system. The converging drum may include a first group of ramp features near a second end of the body for moving cut crop downward, and/or a second group of ramp features near a first end of the body for moving cut crop upward.
