Abstract: The invention relates to a band or strip guiding device (7) for guiding metal bands (B1 to B6) in a band processing system (1) between an inlet conveying section (3) and an outlet conveying section (5). The band guiding device (7) comprises two partial conveying sections (13, 15) arranged one above the other, two switch devices (17, 19) for selectively connecting the inlet conveying section (3) and the outlet conveying section (5) to one of the two partial conveying sections (13, 15), and for each partial conveying section (13, 15) an inlet-side separating device (21, 23) for severing a band (B1 to B6) arranged in the partial conveying section (13, 15), and an outlet-side separating device (22, 24) for severing a band (B1 to B6) arranged in the partial conveying section (13, 15) on the outlet side. Each switch device (17, 19) has a movable clamping device (31, 32) for fixing a band (B1 to B6) in the switch device (17, 19).

The control arrangement provides as input during the harvesting operation in an automatic operating mode the rotational speed of the internal combustion engine as a function of the situation in a harvesting operation of the harvesting machine as controlled by the control arrangement. In addition, the internal combustion engine can be operated in an efficient operating mode at a local minimum of the specific fuel consumption.

Abstract: The invention relates to a remote control for issuing commands to a remote-controlled device in a wireless manner. In said remote control, an assignment mode can run prior to start-up. The remote control also comprises a rechargeable battery for supplying power. The remote-controlled device is equipped with a docking point for the remote control, to which the latter can be temporarily fixed.

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: A drive system for use in utility vehicles, such as agricultural forage harvesters and combines, includes a hydrostatic transmission having a pump driven by a main engine of the vehicle and having first and second motors respectively coupled to front and rear axles of the vehicle by way of first and second differential gear sets. The pump and one or both of the motors have a variable displacement determined by positioning respective swash plates through the agency of a lever, in the case of the pump, and by electronic devices, in the case of the motors, the electronic devices acting in response to control signals sent by a control arrangement, which in turn, operates in response to signals produced by pressure sensors associated with the motors and by signals produced by speed sensors associated with output shafts of the hydraulic motors.

Abstract: A forage harvester includes feed rolls operable to convey crop to a crop cutter drum. The forage harvester is provided with a control arranged to produce a controller output signal based upon a sensed number of rotations of the crop cutter drum or the feed rolls. The controller output signal operates such that a difference between an actual relation between the feed roll and cutter drum speeds and a nominal relation is at least reduced. The control is operable to produce the controller output signal independent from a detection of the speed of the feed rolls or the chopper drum. The speed of the feed rolls or chopper drum is hence controlled without feedback, but with an open loop. Thus, a sensor is saved and control oscillations are avoided.
