Why a flail mower?

  • High quality cutting like a finishing mower with the ability to chop thick residues as a rotary cutter.
  • Different blades available to meet every shredding need.
  • Closer to the tractor and less bulky for storage or manuvering at corners.
  • Safer than rotary cutters near vehicles or pedestrians; Flail mowers don't eject debris sideways.
  • The rear roller avoids scalping.
