US Patent 9334827 Agricultural working machine

An agricultural working system includes a self-propelled agricultural working machine equipped with an attachment in the form of a soil-management device such as a plow, a cultivator, or a harrow, a drive unit that acts as a drive train on land wheels, a control arrangement and a user interface and display unit associated with the control arrangement (5). The control arrangement ascertains the torque loads that occur during the working operation for at least one drive-train component, for example, drive shafts of the land wheels and provides at least one control function on the basis of the ascertained torque loads.
