Features and Benefits

  • Change the cutterbar angle from the cab using the exclusive Vermeer on-the-go hydraulic adjustment.
  • Condition more efficiently with unique, fluted steel rollers and a patented compact roller timing system that improves the conditioner-to-cutter ratio.
  • Choose your conditioning system with either the unique fluted steel rollers or our patented and versatile spring-steel paddles for mowing a variety of crops.
  • Replace blades in seconds using the exclusive Quick-Clip™ Blade Retention System.
  • Move from field to field since the transport width is only a little wider than the actual cutting width.
