An agricultural working machine (1), in particular a tractor, comprises - a vehicle frame (2), - at least two wheel axles (3), - at least three wheels (5, 6) as well as - a control system (7), wherein the wheel axles (3, 4) are connected to the vehicle frame (2) at least indirectly in a force-transmitting manner, wherein at least one wheel axle (3) is formed by a pendulum axle (4) which is pivotably mounted relative to the vehicle frame (2) about a pivot axis (10), wherein at the pendulum axle (3) at least one wheel (5) is formed by a steerable wheel (5) which is pivotably mounted relative to the pendulum axle (4) about a steering axis (19) in such a manner that a steering angle (8) of the steerable wheel (5) with respect to a longitudinal direction (18) of the working machine (1) is changeable, wherein by means of the control system (7) the steering behaviour of the working machine (1) can be improved while avoiding a collision of the steerable wheel (5) with other machine parts. In order to optimize the steering behaviour in different operating modes and at the same time avoid a collision between a steerable wheel (5) and other machine parts, it is proposed that by means of the control system (7), depending on a predefinable steering angle (8) of the steerable wheel (5), a pivot angle (22) by which the pendulum axle (4) is pivotable relative to the vehicle frame (2) about the pivot axis (10) is limitable. [0002] Furthermore, a method for steering an agricultural working machine (1) is described.
