A baler is comprised of a plurality of rollers and two sets of belts supported on the roller and defining a bale-forming chamber for rolling crop material into a cylindrical bale. A guide is mounted on the exterior of the bale-forming chamber and generally parallel to its longitudinal axis. A control wheel is mounted on a support means for mounting the wheel on the guide for movement about an axis perpendicular to the longitudinal axis of the chamber. By movement of the guide, the control wheel may be moved into and out of contact with one set of the belts. The support further carries a twine guide for guiding the entry of twine into the bale-forming chamber during movement of the support to and fro along the transverse guide. The movement of the wheel about the axis perpendicular to the longitudinal axis of the chamber controls the direction of displacement of the support along the guide when the control wheel is engaged with the set of belts. |
