A drive system for a harvesting header of a harvester includes a drive motor, and a drive train connected between the drive motor and one or more driven elements of the harvesting header. The drive train has a variable-displacement hydraulic pump arranged on board the harvester and a hydraulic motor connected in a closed circuit to the hydraulic pump. The hydraulic motor is mounted on the harvesting header and detachably connected by hydraulic coupling connections to the hydraulic pump.

An apparatus for trimming plant material includes a rotatable tumbler through which the plant material is to be axially propagated while rotationally tumbling, and a plurality of cutting reel systems adjacent the tumbler. The plurality of cutting reel systems includes a first cutting reel system adjacent the tumbler, and a second cutting reel system adjacent a landing zone of the rotatable tumbler. The landing zone is an angular range about the axis of the tumbler within which plant material tends to land on the tumbler after tumbling through a central volume of the tumbler.

A bale spreader including one or more rotors rotatably attached to a first and second support member is provided. The bale spreader includes an apron that extends below the rotor(s), and may be configured to operatively feed a particulate material into the rotor(s). The rotor(s) may include a plurality of flail knives or hammers configured to chop and/or shred a particulate material as the rotor(s) is/are rotated. The rotor(s) may be rotated by an optimized hydraulic system connected to the auxiliary hydraulic system of an agricultural implement or vehicle. Furthermore, the bale spreader may include a plurality of tines, screen members, and a flop bar configured to secure particulate material within the bale spreader.

A pre-cutter assembly includes at least one knife rotatable about a knife rotation axis between a retracted position and a deployed position, and an associated engagement arm rotatable about an arm rotation axis between a latch position securing the knife in the deployed position, and a release position allowing the knife to move into the retracted position. A magnet may be positioned for engagement with the engagement arm when the engagement arm is disposed in the latch position. The magnet is operable to apply a magnetic force to the engagement arm when engaged with the engagement arm to hold the engagement arm in the latch position thereby securing the knife in the deployed position. A cam shaft having a cam lobe may be rotated to selectively move the engagement arm between the release position and the latch position.

A pre-cutter assembly includes a first set and a second set of knives. A controller is coupled to a first actuator and a second actuator for moving the first set and the second set of knives between a retracted position and a deployed position respectively. The controller may determine a current baler operating parameter and a status of the first and second sets of knives. The controller may then define a desired positional setting for the first and second sets of knives based on the current baler operating parameter and the status of the first and second sets of knives. The controller may then communicate a control signal to the first and second actuators to control the first and second actuators to position the first and second sets of knives in the desired position setting for the first and second sets of knives.

A transmission device and an agricultural harvesting machine include a first drive input element, a second drive input element, a shift sleeve configured as a hollow shaft, and a drive output shaft. The shift sleeve is mounted axially displaceably on the drive output shaft and is configured to be moved by axial displacement into one of a first position, a second position, and a third shift position. An internal toothing is formed on each of the first drive input element and the second drive input element. An external toothing and an internal toothing are formed on the shift sleeve. An external toothing is formed on the drive output shaft.

An apparatus for roughage processing includes a first platform for placing of a first type of roughage, a first cutting mechanism for processing the first type of roughage, a first chain for moving the first type of roughage from the first platform to the first cutting mechanism; and a second platform, a second cutting mechanism, and a second chain for performing similar tasks with a second type of roughage. The first chain and the first cutting mechanism and the second chain are driven at a different speed to provide concurrent cutting of the first and second types of roughages at different cut sizes. The apparatus further includes a conveyor an auger for concurrently collecting the first type of roughage and the second type of roughage after respective processing by the first cutting mechanism and the second cutting mechanism for effective blending of the two types of roughages, each of which has been cut differently to obtain its optimum particle size for ruminant consumption. The apparatus can be powered by a very small horse power motor. It also includes a mechanism that will stop the floor chains carrying the roughage into the knife drums when the power load force that is detected by the knife drum power load reading device reaches a predetermined amount. This predetermined amount is still within, but near the upper limits of, the available horsepower range of the small motor powering it.
