A towed agricultural implement including a first headstock element for connection to a towing vehicle, a second headstock element supporting a chassis member provided with a plurality of working implements, a pivot pin for connecting the first headstock member and the second headstock member and defining a horizontal axis of rotation between the first headstock member and the second headstock member, in which the second headstock member has a lateral centre of gravity offset from the axis of rotation. A compensating structure is provided between the first headstock member and the second headstock member to offset the unbalanced loads caused by the lateral centre of gravity being offset from the axis of rotation.

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.

The Multipurpose Leaf Crop Harvesting Apparatus and Processing Method will accomplish seven steps in one pass of the combine harvester. This apparatus and processing method harvests leaf crops and is configured to perform multiple processing operations, including fractionation of the leaf crop, leaf maceration, leaf sizing, elevating the leaf fraction to a transport vehicle, and stem conditioning, cutting and windrowing, in a single pass through the crop field. These steps are accomplished using a header unit, an adapter feeder macerator and a forage harvester vehicle, expeditiously removing the leaf fraction from the field. Following leaf fraction harvesting, the leaf fraction is processed by densification into forage feed products. The processed leaf fraction can be combined with other feeds to make up customized feed rations. The stem fraction is also processed. The present invention can also be used to harvest grass crops.

A crop discharge speed control system for a harvesting vehicle having a crop accelerator and a spout that receives crop material and directs the crop material to a targeted destination. The crop accelerator imparts an increased velocity to the crop material. The control system includes a crop velocity sensor, a controller, and a variable speed drive. The sensor is coupled to the spout of the vehicle for detecting a velocity of the crop material in the spout. The sensor produces a velocity signal representative of the velocity of the crop material. The variable speed drive is drivingly coupled to the crop accelerator. The controller varies the speed of the crop accelerator by controlling the variable speed drive, as it controls the variable speed drive to maintain a selected velocity of the crop material dependent upon a modulation of the velocity signal.

A harvesting machine along with a method of operating the harvesting machine. The harvesting machine includes a frame having a first end and a second end. A rotatable pick-up head is pivotally mounted on the first end and is capable of urging a crop into the machine. A cutting mechanism is mounted on a bottom plate for cutting the stems of the plants. A crimper mechanism is positioned downstream of the bottom plate and is capable of compacting the cut stems into a moving web. A moisture removal mechanism is positioned after the crimper mechanism to lower the moisture in the cut stems. A crop converging mechanism is located downstream of the moisture removal mechanism and reduces the width of the moving web into a ribbon. A chopper then chops the ribbon into small pieces so that they can be blown into a storage wagon for transport.

A cutting system for a harvesting header includes a transversely extending cutter bar, a transversely extending knife back, a knife section mounted to the knife back having a knife edge extending generally in a forward direction, a knife guard component having a front guard portion and a rear portion interconnected by a medial portion having a recess. The medial portion is configured for receiving a lengthwise portion of the knife back with the knife section being received into, and the knife section is operable to move transversely into and out of a cutting slot in the front guard portion. A hold down component is located between an upper surface of the rear portion of the knife guard component and an underneath surface of the cutter bar, and an attachment mechanism is operable to secure the knife guard component and the hold down component to the underneath surface of the cutter bar.
