Abstract

A method is provided for controlling a working machine that includes a front section having a frame and a pair of wheels arranged on a geometrical front wheel axis, and a rear section having a frame and a pair of wheels arranged on a first geometrical rear wheel axis and a pair of wheels arranged on a second geometrical rear wheel axis arranged behind the first rear wheel axis. The front section and the rear section are pivotally connected to each other for pivoting about a substantially vertical pivot axis. In a first control mode the wheels of the second geometrical rear wheel axis are steered to substantially follow the same tracks as the wheels of the geometrical front wheel axis when driving the working machine during cornering, and in a second control mode steering the wheels of the second geometrical rear wheel axis follow tracks which are different from the tracks of the wheels of the geometrical front wheel axis.
