A tractor (10) comprises an electronic tractor controller (60). A baler (12) comprises a crop receiving means (126), a baling chamber (112), a bale size sensor (144) associated with the baling chamber (112), and an electronic baler controller (110). The baler controller (110) is operable to submit a halt signal to the tractor controller (60) when a bale size signal provided by the bale size sensor (144) indicates that a bale has reached a size corresponding to a predetermined size. The tractor controller (60) then halts the tractor (10). A steering controller (60) is connected to a swath position sensor (162) and operable to automatically steer the tractor (10) along a swath (130) based upon the signals of the crop swath sensor (162) and of a bale shape sensor (144) such that a uniform bale shape is obtained.
