Abstract
A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.
