Discover the Exmark Radius S-Series Mower

With a compelling blend of speed, power, cut quality and value, the new Radius S-Series is the ideal zero-turn mower for home and acreage owners that demand advanced performance. Choose from 48-, 52- or 60-inch UltraCut Series 3 side-discharge cutting decks equipped with Exmark’s exclusive flow-control baffles for superior cut quality. The deluxe high-back seat features adjustable spring suspension, with molded flip-up armrests to deliver superior all-day comfort for operators of virtually any stature.

Radius S-Series models are designed for maximum durability with reduced maintenance needs. With just two annual grease points, low-maintenance HydroGear transmissions, reliable Kawasaki engines, and long-lasting components, the Radius S-Series is designed to run stronger and longer with less maintenance.

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.
