Abstract
A semi-mounted or trailed agricultural mower has vertical axis crop-cutting rotors and a rigid rectangular open frame mounted above the rotors to support the rotors. The frame has at one end a ground-engageable support wheel secured to a rear beam of the frame and at the other end a headstock secured to a front beam of the frame. At least one of the rotors is trailed from the front beam on a linkage permitting the rotor to rise and fall relative to the frame.
