Claim:
1. An agricultural vehicle comprising: an implement connection hitch which is moveable relative to an axis defined by a rear axle of the agricultural vehicle; a hitch control system controlling movement of the implement connection hitch; and an agricultural vehicle position determining system coupled with the hitch control system and operable to determine a location for the agricultural vehicle; wherein the hitch control system is arranged to: maintain a first operating position of the implement connection hitch relatively close to the rear axle of the agricultural vehicle whilst the agricultural vehicle traverses a first, straight, path whilst operating an attached implement; identify by reference to the agricultural vehicle position determining system, a start of a second, curved, path to be traversed by the agricultural vehicle and the attached implement; and move the implement connection hitch rearwards away from the rear axle of the agricultural vehicle and laterally parallel to the axis defined by the rear axle until the implement connection hitch reaches a second operating position offset rearwards and laterally from a first operating position of the implement connection hitch such as to reduce a turning circle of the agricultural vehicle and attached implement during traversal of the second curved path; wherein at an end of the second curved path, the hitch control system is rearranged to: move the implement connection hitch relative to the rear axle of the agricultural vehicle until the implement connection hitch reaches a third operating position, offset from the first and second operating positions of the implement connection hitch.
