Abstract
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.

A drive system for a harvesting header of a harvester, comprising:
- a drive motor, and
- a drive train connected between the drive motor and a driven element of the harvesting header, the drive train having a variable-displacement hydraulic pump arranged on board the harvester and either a harvester-side hydraulic motor or a header-side hydraulic motor connected in a closed circuit to the hydraulic pump;
- wherein the harvesting header includes a code readable by a control unit of the harvester,
- the control unit is operable to open a valve arranged between the hydraulic pump and the header-side hydraulic motor if it is recognizable on the basis of information associated with the code that the harvesting header includes the header-side hydraulic motor mounted on the harvester header and detachably connect by coupling connections to the hydraulic pump for driving the harvesting header;
- and
- the control unit is operable to open a valve arranged between the hydraulic pump and the harvester-side hydraulic motor if it is recognizable on the basis of information associated with the code that the harvesting header is not equipped with the header-side hydraulic motor for driving the harvesting header.
A harvester, comprising:
- a harvesting header;
- a drive motor;
- a drive train connected between the drive motor and a driven element of the harvesting header, the drive train having a variable-displacement hydraulic pump arranged on board the harvester and either a harvester-side hydraulic motor or a header-side hydraulic motor connected in a closed circuit to the hydraulic pump;
- wherein the harvesting header includes a code readable by a control unit of the harvester;
- wherein the control unit is operable to open a valve arranged between the hydraulic pump and the header-side hydraulic motor if it is recognizable on the basis of information associated with the code that the harvesting header includes the header-side hydraulic motor mounted on the harvester header and detachably connect by coupling connections to the hydraulic pump for driving the harvesting header;
- and
- the control unit is operable to open a valve arranged between the hydraulic pump and the harvester-side hydraulic motor if it is recognizable on the basis of information associated with the code that the harvesting header is not equipped with the header-side hydraulic motor for driving the harvesting header.
A harvester comprising:
- a frame;
- a harvesting header detachably coupled to the frame;
- a variable-displacement hydraulic pump arranged on board the frame, and either a header-side hydraulic motor of the harvesting header or a harvester-side hydraulic motor provided on the frame connected in a closed circuit to the hydraulic pump;
- a valve;
- a control unit operable to read a code from the harvesting header and open the valve to provide hydraulic fluid to the header-side hydraulic motor on the basis of information associated with the code indicating that the harvesting header includes the header-side hydraulic motor;
- and
- wherein the control unit is operable to open the valve to provide hydraulic fluid to the harvester-side hydraulic motor to drive the harvesting header when the harvesting header is not equipped with the header-side hydraulic motor.
