ABSTRACT:
A linkage for equalizing the biasing forces exerted on the opposing transverse ends of the upper conditioning roll in a mower-conditioner is disclosed wherein a separate torsion bar is utilized to bias each respective end of the upper conditioning roll toward the lower conditioning roll, each torsion bar being connected to a biasing force equalization member for equalizing the pressure exerted on the opposing transverse ends of the upper conditioning roll. The equalization member includes a pair of arms interconnected by a trunnion to permit a limited relative movement between the two arms to accommodate differences in manufacturing tolerances in the torsion bars. An adjustment crank is connected to the trunnion to effect a selective simultaneous movement of the arms to vary the roll pressure.
