Abstract
A mower conditioner includes upper and lower conditioner rolls with the upper roll extending between, and being rotatably mounted to, a pair of vertically swingable arms. A linkage arrangement is coupled between the frame supporting the arms and the arms, with one part of the linkage being associated with a stop for limiting the range of movement of the upper roll toward the lower roll, and with another part of the linkage being coupled to a spring arrangement for biasing the upper roll toward the lower roll. The stop is configured as a pair of wedge-shaped members having respective inclined surfaces engaged with each other and held in an adjusted position by a nut and bolt arrangement, the range of movement of the upper roll toward the lower roll changing in response to tightening or loosening the nut on the bolt.
