Abstract: A method of regulating a travelling speed of an agricultural machine includes providing a diesel engine to drive a variable displacement pump, the variable displacement pump connected by a hydraulic line to at least one hydraulic motor connected to a running gear so as to drive the agricultural machine at the travelling speed. The method further includes measuring a speed of the diesel engine, and providing a delivery volume from the variable displacement pump via the hydraulic line to the at least one hydraulic motor in proportion to the measured speed of the diesel engine, where a speed of the at least one hydraulic motor controls the travelling speed of the agricultural machine.

Abstract: A traveling gear for an agricultural working machine, with control of he traveling speed by adjusting the engine sped to the planned driving for road travel is disclosed. The traveling gear for an agricultural working machine controls the speed for road travel by controlling the central drving gear.

Abstract: A traveling gear for an agricultural working machine configured to adjust an engine speed so as to control the traveling speed of the agricultural working machine for road travel. The traveling gear generally controls the traveling speed of the machine by controlling a central driving gear. The traveling gear generally includes a diesel engine as its central motive power source, a variable displacement pump driven by the diesel engine, an electro-hydraulic motor with an adjustable induction volume, and a pair of electro-hydraulic motors which are switchable in their induction volume. For a change in speed, the displacement volume of the variable displacement pump is adjusted. The change in displacement of the variable displacement pump causes a change in speed of the electro-hydraulic motors, which in turn causes a corresponding change in speed of the traveling gear and associated traveling speed of the agricultural machine.

Abstract: A crop harvesting machine is provided having a crop feeder device that is movable through various heights via manipulation of first hydraulic cylinders. A crop gathering attachment is mounted onto a front side of the crop feeder device. A crop gathering attachment is provided having fixed height sensors that measure a distance of the attachment above the ground. A second hydraulic cylinder is provided between the crop feeder device and the crop gathering attachment to control the angle of tilt of the crop gathering attachment relative to the crop feeder device. The angle of tilt is measured by a tilt sensor. A controller is connected to the sensors and provides output to the cylinders to control the machine height and angle of tilt.

Abstract: The invention relates to a device for adapting attachments on harvesting machines to the ground surface, in particular for combine harvesters and forage harvesters. The aim of the invention is to produce a rapid adaptation to the ground surface, even at high speeds, that is extremely accurate and also cost-effective. To achieve this, a feed device (1), whose height can be adjusted by a hydraulic cylinder (5). has a shaft (7) which is aligned transversally to the direction of travel, the attachment (15) being mounted so that it can be rotated through a defined pivoting angle (9) about said shaft. The pivoting angle (9) can be modified by means of a hydraulic working cylinder (10) which connects the feed device (1) and the attachment (15), whereby the pivoting angle (9) is continuously monitored by a sensor (11). An additional sensor (18) continually measures the distance (17) of the attachment (15) to the ground surface.
