Lift and suspension system
    • Heavier floatation spring controlling ground pressure

      Heavier floatation spring controlling ground pressure

    A lift and suspension system allows for the R240, R280, and R310 models to raise the cutterbar off the ground without raising the tractor’s hitch.

     

    The disc mowers use the hydraulic cylinder to lift the cutterbar from cutting to the transport position, and the cutterbar automatically locks into place.

     

    A longer cylinder on the R240 and R280 allows for a cutting arc of +35 degrees to -25 degrees. A longer cylinder on the R310 allows for a cutting arc of +35 degrees to -30 degrees.

     

    A heavier spring establishes even flotation along the full length of the cutterbar in a variety of different field conditions and topography.

  • Performance

    • Cutting arc provides a wide range of cutting angles
Easy-to-attach 3-point hitch tractor hookup
  • Easy-to-attach 3-point hitch Easy-to-attach 3-point hitch

    The R240, R280, and R310 Mowers attach to tractors with a Category 2, 3-point hitch and all three models are quick-hitch compatible.

    The R240, R280, and R310 models have a built-in parking lock that holds the 3-point arms up, making tractor hookup quick and easy.

  • Adjustable lower hitch pins Adjustable lower hitch pins

    Lower hitch pins can be adjusted left or right to match the mower offset for tractors with wider tire spacing.

     

    The R240, R280, and R310 models have an offset range of 105 mm (4 in.).

  • Optional long hitch pinOptional long hitch pin

    Adjustable lower hitch pins and an optional longer hitch pin allow for use with tractors of various tire spacing.

     

    Available through Parts: an optional long hitch pin increases mower offset to 200 mm (8 in.) for tractors with even wider tire spacing.

    Each disc has two free-swing knives:

    • Easy to remove and replace
    • Two cutting edges, doubling the use life
    • Swings away to reduce possible damage if a solid object is struck
Heavy-duty driveline with overrunning clutch
    • Optional rearward-swinging hydraulic cylinder

      Optional rearward-swinging hydraulic cylinder

    A heavy-duty driveline with overrunning clutch is standard equipment on R240, R280, and R310 Mowers.

Heavy-duty cutterbar for the toughest cutting conditions
  • Rotary disk cutterbar  Rotary disk cutterbar

    A multi-V-belt drive system transfers power from the gearbox to each rotary disc.

     

    Power is transmitted to the rotary discs through fully enclosed gears, running in oil, for quiet, smooth, reliable operation.

  • Convenient belt adjustment location (R240, R260, R310)Convenient belt adjustment location (R240, R260, R310)

    All models have a spring-loaded belt tensioner for easier belt adjustment. The belt tension automatically compensates for initial belt stretch, increasing belt life.

    • High-speed rotary disks

    Rotating at 2986 rpm, the high-speed discs cut in the toughest conditions.

    The low-profile cutterbar allows a close cut while maintaining a level cutterbar. The cutting height is controlled by adjusting the tilt of the cutterbar.
