Features

Features

  • ULTRACUT DECK TECHNOLOGY: Exmark’s exclusive UltraCut decks are featured on Radius models. Every UltraCut cutting deck features Exmark’s exclusive maintenance-free, sealed-bearing spindle assemblies for increased durability and reduced downtime, combined with zero maintenance.
  • HEAVY DUTY FABRICATED FRAME: With a fully welded frame built from 2x3-inch frame tubes, the Radius design places major components including the engine, hydro drive system and fuel tank lower in the frame. The lower center of gravity and better mass centralization results in increased traction and stability, with improved handling.
  • ADJUSTABLE ROLLOVER PROTECTION SYSTEM (ROPS): A new adjustable ROPS system is easy to fold up-and-down, and is built from round tubes for easy, flexible accessory placement. (Available Spring 2023)
  • HEIGHT OF CUT MADE EASY: Our patented height of cut adjustment system is user friendly and allows the operator to quickly and accurately select height of cut from the operator seat.
  • FULL-SUSPENSION OPERATOR SEAT: Radius S- and X-Series models feature an adjustable full-suspension operator seat, with three inches of suspension and an EVC stretch foam base for superior all day mowing comfort.
  • FULLY GUARDED ENGINE: With strong steel lower protection and durable composite upper protection, the Radius S-Series engine is well guarded against damage from foreign objects.
