A system for wrapping a material in a baler includes a feed element for feeding the material through a feed path. A drive element intermittently drives the feed element. A linking element couples the drive element with the feed element. A tensioning lever operates to vary tension on the linking element to intermittently drive or not drive the feed element. A knife mechanism operates to intersect the feed path to cut the material. An actuator moves the tensioning lever and the knife mechanism. A spring limits motion of the actuator based on a threshold magnitude of the tensioning lever so that the linking element is not over tensioned.
