1. A self-propelled agricultural harvesting machine that is propelled in a normal forward operating direction and is provided with a chassis that includes a harvested crop processing arrangement arranged within the chassis and an intake conveyor arranged on the front side of the chassis, a front harvesting attachment take-up arrangement attached to said intake conveyor, and a front harvesting attachment for the take-up of harvested crop attached to the intake conveyor, wherein the front harvesting attachment take-up arrangement is pivoted by a front harvesting attachment pivoting actuator about a vertical axis relative to the chassis, said front harvesting attachment and said front harvesting take-up arrangement being closely coupled to said intake conveyor, wherein the chassis includes a pair of front devices in contact with the ground and wherein rear devices in contact with the ground are arranged behind the front devices in contact with the ground relative to the normal forward operating direction and are steered by means of a steering actuator, and the front harvesting attachment pivoting actuator is coupled so as to drive with the steering actuator, and wherein the steering actuator and the front harvesting attachment pivoting actuator are selectively coupled, in such a way that the front harvesting attachment take-up arrangement and the rear devices in contact with the ground are moved in opposite directions or in the same direction.
