Abstract: The agricultural harvesting machine having a crop picking head includes a pickup conveyer which can be driven so as to pick up the harvested crop at a first adjustable speed, a discharge conveyer which can be driven so as to receive the harvested crop picked up by the pickup conveyer, transport the harvested crop, and discharge the harvested crop at a second adjustable speed, and a feed-in conveyer disposed in a feed-in channel of the harvesting machine that can be driven so as to receive the harvested crop from the discharge conveyer, transport the harvested crop, and discharge the harvested crop to a harvested crop processing unit at a third adjustable speed. The third speed and the first speed are independent of one another, and the second speed is defined by the first and third speeds and falls in a range between the first and third speeds.

Abstract: A drive system of a working vehicle including a main engine drivingly connected to a hydraulic pump. The hydraulic pump is connected to first and second hydraulic motors. When an undesirable operating condition is detected, a control device shifts an actuator associated with at least one of the wheels, to reduce the displacement volume of the hydraulic motors driving that wheel. In addition, shifts are made in the actuator of the respective other hydraulic motor and/or in the actuator of the hydraulic pump, in order to maintain a constant speed of travel. The control device shifts the actuator of the hydraulic motor of the other wheel toward greater displacement, and if that shift is insufficient to compensate for the undesirable operating condition, the control device will shift the actuator of the hydraulic pump in the direction of reduced displacement volume.

Abstract: An automatic steering of an agricultural tractor on a surface of a field to be processed is accomplished by equipping the tractor with a camera for taking a picture of a region of the field, which is in front of the tractor, including the surface that is to be processed, generating a pixel data file from a picture signal of the camera, generating texture information with respect to the texture of the surroundings of the pixels contained in the data file, classifying the pixels of the pixel data file while considering the texture information, in order to generate a binary information as to whether or not a particular pixel is to be associated with the surface that is to be processed, generating a steering signal based on the results of the classification, and repositioning the steering device of the harvesting machine according to the steering signal so that the machine is steered automatically along the surface that is to be processed.

Abstract: A self-propelled harvesting machine having an internal combustion engine, a propulsion system that can be operated to cause the harvesting machine to move across a field with a propulsion speed, a crop material pick-up device for picking up the crop material from a field, a crop material processing device for processing the crop material that has been picked up, a control unit for specifying the speed of the internal combustion engine, and a through-put measurement device for determining the through-put of the harvesting machine. The control unit can be operated to vary the speed of the internal combustion engine depending on the signal from the through-put measurement device. In this manner the RPM of the internal combustion engine that is most favorable in terms of fuel consumption and that corresponds to the power to be applied at a given through-put can be specified.

Abstract: Disclosed is a radio control device which is used for issuing commands in a wireless manner to a remote controlled apparatus and in which an allocation mode can be run before said radio control device is operated. The inventive radio control device comprises a transmitter/receiver unit, a control mechanism, and at least one antenna. Once the user has triggered the allocation mode, the radio range of the remote control device is lowered such that communication can be established only with an apparatus that is located in the immediate vicinity of the remote control device and returning to the standard range is possible only once the allocation process has been completed.
