A combine harvester with a variable length wheelbase. For example, a combine harvester may have a chassis defining a forward end and a rear end, a feeder house at the forward end of the chassis, a first set of ground-engaging elements supporting the forward end of the chassis, and a second set of ground-engaging elements supporting the rear end of the chassis. The second set of ground-engaging elements are configured to move forward and rearward relative to the chassis.

An agricultural harvester includes a controller configured to receive at least one wing angle signal indicative of an angle at least one wing with respect to a center section of a header. The controller is also configured to receive a wing height position signal indicative of a distance between the at least one wing and a soil surface, determine whether the angle of the at least one wing exceeds an angle limit threshold based at least in part on the wing angle signal, and output a tilt signal to a tilt actuator in response to determining the angle of the wing exceeds the angle limit threshold. The tilt signal is indicative of instructions to maintain the distance between the at least one wing and the soil surface within a target distance threshold.

A header positioning system for controlling a position of a header for a combine harvester. The header positioning system including a controller that is configured to receive signals corresponding to (i) a measured inclination of either the header or the combine, (ii) a measured ground speed of the header or the combine, and (iii) a measured height of the header with respect to ground. The controller is further configured to adjust a height and a pitch of the header as a function of the inclination, measured ground speed and the measured height.

A combine harvester for carrying out an agricultural harvesting process has a plurality of working units and a driver assistance system for controlling at least some of the working units. The combine harvester accommodates as working units a chaff cutter for comminuting harvested produce and a produce distributing arrangement in the rear area of the combine harvester downstream of the chaff cutter for distributing harvested produce on the field soil in adjustable throw directions. The respective throw direction comprises vector components of a horizontal throw direction and a vertical throw direction. The driver assistance system is adapted to optimize the control of the produce distributing arrangement by at least one of the substrategies including “throw direction correction” and/or “inclination-dependent produce distribution” and/or “produce distribution in longitudinal direction” and/or “produce distribution in transverse direction” with respect to at least one optimization criterion.

A self-propelled combine harvester has at least one tilting mechanism for the uniform distribution of a harvested material on an oscillating conveying and cleaning unit, in particular a top sieve. The tilting mechanism has elements for defining a swiveling direction of the conveying and cleaning unit which are arranged between the conveying and cleaning unit and a machine housing. The tilting mechanism has an actuator for continuous adjustment of at least one component part of the elements from an initial position to an adjusting position. The position of the at least one component part decisively defines the swiveling direction. An electric control unit controls the actuator depending on a state of the combine harvester and/or harvested material and the initial position of the at least one component part of the tilting mechanism.

Work equipment configured to unload a collected article from the storage container and resistant to tipping over when unloading the collected article. The work equipment includes a vehicle body; a storage container provided on the vehicle body so as to be moveable between a horizontal position for storing a collected article and an inclined position for unloading the collected article; a drive unit provided between the vehicle body and the storage container and configured to change a container inclination angle defined as an angle of the storage container with respect to the vehicle body; an inclination angle sensor detecting a vehicle body inclination angle defined as an inclination angle of the vehicle body with respect to a horizontal plane; and a control unit configured to control a driving operation of the drive unit according to the vehicle body inclination angle.

A system for recognizing an operating intention at an operating unit that can be actuated manually includes an image capture unit for monitoring a capture region surrounding the operating unit for an entering hand in order to capture it in terms of a positioning of a palm of a hand or of one or a plurality of fingers in relation to the operating unit and to generate corresponding image information. An evaluation unit is provided for comparing the generated image information with at least one image pattern that is characteristic for an operating intention from a pattern memory. In the event of a correspondence that lies within a permitted variation range, a controllable function is enabled on the part of the operating unit.

A self-propelled harvesting machine for harvesting a crop field has a ground drive including multiple working units, a control system and a sensor system. The sensor system periodically emits transmitted pulses of electromagnetic transmission beams in at least one transmission direction onto the crop field and the transmitted pulses are reflected on the crop field and are received as echo pulses by the sensor system. For at least one portion of the transmitted pulses, different partial beams of a single transmission beam are reflected by plants of the crop field lying one behind the other with a time offset, so the particular resultant echo pulse is composed of time-offset partial echo pulses. The control system determines a value for the crop density on the basis of a time correlation within the resultant echo pulse, and controls the ground drive and/or the working units on the basis of the determined crop density.
