Product Overview
Whether you’re upgrading from an older machine or are looking to add another zero-turn to your trailer, the new Radius S-Series delivers an unbeatable combination of durability, operator comfort, performance, and value. Choose from 48-, 52-, or 60-inch UltraCut Series 3 side-discharge cutting decks, each equipped with our exclusive flow-control baffles for a superior cut quality. An adjustable full-suspension operator seat and isolated footrest provide superior all-day mowing comfort.

Radius S-Series models are also designed for maximum durability with reduced maintenance. With just two grease points to lubricate annually, low-maintenance Hydro-Gear integrated transmissions, and reliable Kawasaki commercial engines, Radius S-Series models are built for the long haul.

Features May Include:

• 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)
  An adjustable ROPS system is easy to fold up-and-down, and is built from round tubes for easy, flexible accessory placement.
• 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.
