Abstract: A system and method of capacitance management in an agricultural vehicle and connected implement, wherein the vehicle and implement have a plurality of electric drives connected to a common connection and connectable to a direct current supply, and each electric drive has an associated Y capacitor between each direct current supply connection and the common connection, wherein the method includes receiving and summing capacitance values for each of the electric drives and comparing with a stored threshold value. If the threshold value is exceeded, a sequence of selective disconnections of individual electric drives is performed until the sum of the received capacitance values is less than or equal to the threshold value. The method may be performed manually, or automatically based on a sequence defined in a priority list until the sum of the received capacitance values is less than or equal to the threshold value.

Abstract: A system and method for generating land maps of a land area. The land maps can include two-dimensional and three-dimensional land maps. The land maps may be efficiently generated based on field data obtained by mobile machines configured to traverse the land area, with the mobile machines associated with one or more sensors. The land maps may be used to accurately and efficiently guide other mobile machines as such mobile machines traverse through or operate within the land area.

Abstract: A method and system for selecting and indicating to a user one from a plurality of available ballasting options for an agricultural vehicle when coupled to an agricultural implement. The implement type defines operating ranges of discrete values for first, second and optionally third operational parameters of the vehicle, with the differing combinations defining a values subset. An optimal choice from the available ballasting options is made for each combination in the values subset, and a selection from the optimal choices based on prevalence or probability of occurrence is made and presented to the user. Operational parameters may include operating speed, loading due to implement weight and engine power.

Abstract: An agricultural vehicle has an implement connection hitch which is moveable relative to a rear axle of the vehicle. A system for controlling movement of the connection hitch is coupled with position sensors such as a GPS receiver. During turning maneuvers, the control system moves the hitch relative to the rear axle of the vehicle until it reaches an offset position such as to reduce the turning circle of the vehicle and a connected implement. The extent of offset may be determined automatically by the control system on identification of a connected implement.

Abstract: An agricultural vehicle has an implement connection hitch including means for controllably moving the same relative to a rear axle of the vehicle under the direction of a vehicle control system. Under user control from a cab of the vehicle, the hitch is moved rearward from the vehicle until it reaches a first position at a chosen distance from the rear axle. Following the attachment of a known implement to the hitch, the control system retracts the hitch and implement toward the rear axle to a second position at a distance from the rear axle determined in the control system optionally at least partly on the basis of the identity of the implement. The identity of the implement may be input by the user or determined via an ISOBUS connection.

Abstract: The invention relates to a transmission synchronisation method and a transmission synchronisation device for at least two transmission units (T1, T2). The synchronisation takes place in that in each case an output revolution speed (n1, n2) of an axle drive shaft arranged in a transmission (T1, T2) is adjusted by means of a first and second adjustment unit (ADU1, ADU2). The synchronisation of the first and second transmissions (T1, T2) takes place by a result value (cal_out) of an arithmetic logic unit (140) being conducted to the second adjustment unit (ADU2) arranged at the second transmission (T2), dependent on the first transmission (T1) and on the reference value (v_set) of a preselection unit (100).
