A drive arrangement for the reciprocating drive of a cutter bar comprises a hydraulic gear motor with a housing and a gearwheel, which is set in motion around a first axis by a hydraulic medium, and an eccentric drive, which comprises an eccentric element that can be rotatably driven by a gearwheel around a second axis parallel to the first axis, and a drive element connected to the eccentric element, which is, or can be, connected to the cutter bar.

A forage harvester has multiple working elements for carrying out a crop handling process, a drive system which is divided into a main drive train that includes mechanically driven working elements, and an auxiliary drive train that includes hydraulically driven working elements, a driver assistance system which comprises a memory for storing data and a computing device for processing data stored in the memory, as well as a graphical user interface. The working elements consist of at least one adjustable crop handler, at least one actuator system for adjusting and/or actuating the crop handler, and a control unit for controlling the actuator system. The working element is designed as an automatic adjuster whose mode of operation can be optimized by the driver assistance system. The driver assistance system feeds a throughput-proportional load signal, which can be determined by at least one sensor system, to the particular automatic adjuster.

An articulating mower deck system. The system is adapted to disable power to a blade associated with the wing deck section before the wing deck section begins to liftfrom an operating position toward a folded positionyet does not interfere with blade operation when the wing deck section floats relative to a center deck section during normal operation of the deck. Articulating decks of modular construction are also provided, allowing assembly of multiple deck widths with a minimum of modular deck sections.

A hydraulically driven tractor has a header drive system including a header drive motor and a header drive pump driven by an engine for generating a source of hydraulic fluid under pressure for the header drive motor, and a ground drive system including a wheel drive motor and a wheel drive pump driven by the engine for generating a source of hydraulic fluid under pressure for the wheel drive motor. A controller receives input from sensors so as to monitor: a header drive demand value, a wheel drive demand value, an engine load value, and/or an engine RPM value for comparisons to acceptable threshold range to vary the target throttle value if outside of one of the ranges. The controller can also vary the displacement of the wheel drive pump and/or the wheel drive motor in response to variation of the target throttle value to maintain ground speed.

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.

An agricultural harvester has a header and feeder drive system including a forward belt drive arrangement and a reverse belt drive arrangement. The forward belt drive arrangement includes a forward drive belt and a forward belt drive tensioner operated by an actuator. The reverse belt drive arrangement includes a reversing motor and a reverse drive belt selectively engaged with the feeder drive system by operation of the same actuator.

An agricultural trailed implement includes a chassis with tongue for hitching to a tractor. A housing is integrated into a loadbearing section of the tongue. A pump or generator is mounted inside the housing and is driven by a PTO shaft connected to an attached tractor. The pump housing may define a sump which provides a fluid reservoir to supply the pump in a hydraulic circuit.

A header comprising an inlet line, a check valve, an accumulator and a hydromechanical transmission system is disclosed. The inlet line is used to receive a first pressure of hydraulic fluid and be in communication with the check valve. The accumulator is located downstream the check valve and in communication with the inlet valve. The hydromechanical transmission system includes a pressure line in communication with the inlet line that is downstream the accumulator and a closed hydraulic circuit in communication with the pressure line having a hydrostatic pump and a variable speed motor.

A method for operating an agricultural vehicle, the method including: generating an overdrive torque at a drive wheel motor of at least one ground drive system; transmitting the overdrive torque to the engine via a hydraulic ground drive circuit and a ground drive pump, to thereby bias the engine to operate at an increased rotation speed; measuring an engine rotation speed; comparing the engine rotation speed to a threshold value; and upon determining that the engine rotation speed satisfies the threshold value, operating the auxiliary hydraulic component of an auxiliary hydraulic system to generate a braking torque at a respective auxiliary pump, and transmitting each the braking torque to the engine to bias the engine to operate at a decreased rotation speed. An agricultural vehicle having a control system to perform the method is also provided.

A high efficiency work vehicle drivetrain contains a variator having an inline dual planetary configuration. The work vehicle drivetrain includes an engine, an auxiliary power takeoff (PTO) shaft coupled to the engine and rotatable about a primary power path axis when driven by the engine, and the variator assembly. The variator assembly includes a variator motor and a variator gearbox. The variator gearbox contains a planetary gear system, which is coupled to the variator motor and to the auxiliary PTO shaft. The planetary gear system is rotatable about a planetary axis, which is coaxial with the primary power path axis.
