An automatic bale wrapping assembly for a machine that forms round bales of windrowed crop material and includes a mobile main frame with a bale forming assembly having a bale forming region defined by an upper conveyor and a lower conveyor that feeds the crop material to the bale forming region and rotates the material during and subsequent to bale formation. The bale wrapping assembly has a twine dispensing arm, from which a free end of a twine supply extends, a moveable support for the dispensing arm, a locking mechanism for releasably securing the dispensing arm in a rest position, coacting members on the bale forming assembly and the main frame for automatically actuating the locking mechanism when a bale being formed reaches a predetermined diameter, a spring member for moving the dispensing arm in one direction upon release thereof by the locking mechanism to a bale wrapping position whereat the free twine end is threaded about one end of the bale, a hydraulic motor for moving the dispensing arm in an opposite direction along the formed bale to wrap the twine about the length of the bale, and a cutter assembly for cutting the twine at the completion of the bale wrapping operation.
