An Agricultural vehicle has a frame supported by a front pair of wheels and a back pair of wheels, wherein the back pair of wheels are steerable and wherein each wheel of the back pair of wheels is connected to the frame via a respective intermediate support element that is pivotable with respect to the frame in such a manner that the back pair of wheels are movable between a first position wherein the back pair of wheels defines a first track width and are positioned at a first distance from the front pair of wheels, and a second position wherein the back pair of wheels defines a second track width and are positioned at a second distance from the front pair of wheels, wherein the first track width is larger than the second track width and wherein the first distance is smaller than the second distance.
