A simplified mechanism for feeding a plurality of individual twine strands into a bale forming chamber for wrapping a bale that allows user-selectable adjustment of twine strand spacing along the bale length so that an optimal number of circumferential twine wraps around the bale necessary to secure the bale after discharge from the bale forming chamber may be selected. The simplified thus enables the spacing between twine strands to be optimized for various crop materials that are being baled.
