Abstract
A crop conditioner includes a frame mounting a bottom fixed roller and a top liftable roller. The top roller is liftable at each end on a pivot member tensioned by a tension link, a tension spring and a bell crank connected between the tension link and the spring. The bell crank is mounted on the conditioner frame for pivotal movement about a pivot axis which lies transversely to a line parallel to the pivot axis of the second roller so that the bell crank extends from the tension link to the tension spring in a direction outwardly of the radial plane of the roller pivot axis. The spring extends upwardly and forwardly from the bell crank pivot at a rear flange of the frame to an adjustment screw of the spring at a top flange of the frame immediately adjacent an adjustment of a bottom stop of the top roller.
