Embodiments of the present disclosure relate generally to generating and utilizing three-dimensional terrain maps for vehicular control. Other embodiments may be described and/or claimed.

The invention relates to a method (100) for operating an agricultural machine (1, 201) on a useful agricultural area (4, 5), comprising a traction vehicle (2) and a working appliance combination (3, 203) connected to the traction vehicle (2) in the form of a mower and/or rake, the harvest goods being processed with a plurality of working devices (33a-33d, 233a-233c), which are arranged so as to project from a carrying frame (31, 231a-231b) transversely with respect to the direction of travel (F) of the working device combination (3, 203), wherein the working appliances (33a-33d, 233a-233c) can each be raised and lowered independently of one another in order to move the working appliances either into a headland position or into engagement with the harvest goods, characterized in that when processing by means of a preferably satellite-assisted navigation system (21), position data of the working device combination (3, 203) is acquired continuously and, from the same, at least one already processed field area (41, 51) is determined and recorded (112), and in that the working devices (33a-33d, 233a-233c) are each raised automatically (113) on the basis of their positions when reaching the at least one already processed field area (41, 15) again, and/or in that the working devices (33a-33d, 233a-233c) are each automatically lowered (114) on the basis of their positions when moving out of the at least one already processed field area (41, 51 into a field area (42, 52) that is still to be processed.

A lateral tilt control system for an agriculture harvester may include first and second tilt cylinders coupled between a support structure and an implement of the harvester. The first tilt cylinder may include a first cap-side chamber and a first rod-side chamber and the second tilt cylinder may include a second cap-side chamber and a second rod-side chamber. The system may also include a first fluid line providing a flow path between the first cap-side chamber and the second cap-side chamber and a second fluid line providing a flow path between the first rod-side chamber and the second cap-side chamber. Additionally, the system may include a pressure relief valve coupled between the first and second fluid lines to allow fluid to be transferred between the first and second fluid lines when a fluid pressure within either fluid line exceed a relief pressure setting.

A chassis-height adjustment system for selectively raising and lowering a chassis relative to a ground surface includes a plurality of support assemblies supporting a chassis on respective ground-engaging elements. Each support assembly has a height adjustment actuator. Each height position sensor senses an adjustment position one of the height adjustment actuators and generates a height signal. Each of the support assemblies may be mounted to the chassis by a track-width adjustment mechanism having a track-width adjustment actuator. The height adjustment system is controlled in a manner to synchronize each height adjustment actuator with the other actuators. Adjustment of one or more height adjustment actuators is slowed or stopped in the event that other actuators need to catch up. The track-width adjustment actuators may shift the position of the associated ground-engaging element laterally relative to the chassis to keep the ground-engaging elements from sliding laterally as the chassis height changes.
