Abstract
Abstract A twine cut and clamp mechanism for a roll baling machine includes a pair of arms and a pair of intermeshing spur gears connected, respectively, to the arms. A lever is connected to one of the arms to pivot it. The spur gears cause concurrent pivoting of the other arm when the one arm is pivoted by the lever.
