A drive arrangement of a conditioning apparatus of a forage harvester having two conditioning rollers, with at least one of the conditioning rollers able to be driven at variable speed via an electrical drive train, includes an electric motor/generator for driving the conditioning roller. The electric motor/generator is able to be operated as a generator for braking the conditioning roller and to return the generated electrical energy into a drive system of the forage harvester.

A method for controlling one or more operating parameters of a forage harvester includes picking up harvested crop from a field by means of a harvesting attachment, processing the harvested crop by means of a chopping device and/or a post-processing device, and ejecting the processed harvested crop onto a loading container. An image of the processed ground-borne harvested crop is recorded by a camera, and an operating parameter of the forage harvester is set or adjusted with a control unit using the image.

An arrangement for data recording and sampling for an agricultural machine includes a sensor set-up arrangement to detect properties contained in a material stream, means of taking a sample of the material from the material stream, and an electronic control unit. The control unit is configured to perform the following steps in response to a tripping signal: (a) instruct an actuator to bring the means into a position for sampling; (b) starting a recording of raw sensor arrangement data in a memory; (c) after depositing the sample at a desired sampling location, stop recording the raw data and instruct the actuator to return the means from the sampling position to an inactive position; and (d) store identification data to identify the sample together with the raw data in memory.

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.

The invention relates to a drive system for an infeed conveyor () of a harvester (), having an adjustable hydraulic pump (), the flow rate and flow direction of which can be adjusted by means of a first actuator (), said hydraulic pump being connected to a hydraulic motor () which drives the infeed conveyor (). A controller () is connected to a foreign-body detection device () and to a first valve () for controlling the actuator () that controls the hydraulic pump (). The controller () controls the first valve () at least for a short time by reversing the flow direction is a foreign body appears. In addition, it is suggested that the hydraulic motor () has an adjustable displacement volume, and that the controller () increases the hydraulic motor displacement volume () is a foreign body appears.

A self-propelled harvesting machine is provided that has operating devices to take-up and/or process harvested crop, which can be driven by means of a drive belt, that can be driven by a belt pulley about an axis of rotation extending horizontally and transverse to the forward operating direction of the harvesting machine. Two internal combustion engines are provided on the harvesting machine and each are supported on the frame arranged side by side alongside each other relative to the forward operating direction, with crankshafts extending in the forward operating direction. A connecting gearbox is arranged ahead of the internal combustion engines in the forward direction of operation and is connected or can be connected so as to drive with the first crankshaft, the second crankshaft and the belt pulley. The connecting gearbox includes two angle gearboxes that are connected to a transverse shaft arranged in the transverse direction that is connected or may be connected, in turn, with the belt pulley.

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.

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.

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. The control arrangement has a memory for storage of data, such as maximum legal ground speed and the ratio of the speeds of the axles as results from a given wheel size, and uses this information for controlling the hydrostatic transmission such that the vehicle does not exceed the speed, and the front and rear axles are driven so as to produce the same ground speed.

Drive system of a utility vehicle

A drive system for a utility vehicle ( ) containing a motor ( ) that is connected to and drives a hydraulic pump ( ) which, in turn, is connected to a hydraulic motor ( ). The hydraulic motor drives a ground engaging element through a gearbox having different selectable gears. A speed-adjustment device ( ) cooperates with the hydraulic pump ( ) and/or the hydraulic motor ( ) to adjust the rotational speed of the hydraulic motor ( ). In order to make available the full rotational speed range of the hydraulic motor ( ) in the lower gears while ensuring the observation of the maximum permissible speed in the highest gear, the invention provides a control device to limit the rotational speed of the hydraulic motor ( ) to a predetermined value if the highest gear(s) of the gearbox ( ) is selected.

A crop harvesting machine includes a crop transport or feed mechanism including a feed roller to which a toothed wheel is fixed. A detent in the form of a pivotally mounted lever carries a cam or tooth, the detent being pivotable between a first position wherein the cam is engaged with the toothed wheel so as to block rotation of the feed roller, and a second position wherein the cam is disengaged from the toothed wheel so as to permit free rotation of the crop feed roller. A one-way hydraulic cylinder is coupled to the detent in parallel with a tension coil spring and is controlled by a solenoid control valve, coupled in a control circuit forming part of a metal detector circuit, so as to be pressurized for moving the detent to its first, blocking position when the metal detector sensor senses an undesirable metal object in the crop, and so as to be coupled to sump so that the spring moves the detent to its second position, permitting rotation of the crop feel roller, when no metal is detected.
