  • Publication number: 20180328470
    Abstract: In accordance with an example embodiment, a mower-conditioner may include first and second conditioning rolls, at least one eccentric assembly, and a linkage. The first and second conditioning rolls are spaced apart a distance. The at least one eccentric assembly is coupled to the mower-conditioner.
