Features
Full-Suspension Operator Seat
The Radius S-Series upgrades to a deluxe full-suspension operator seat to minimize bumps and vibration that reach the operator. When combined with the large 23-inch drive tires, the Radius S-Series delivers a smoother ride for increased operator comfort and decreased fatigue.
UltraCut Series 3 Cutting Deck
Fabricated and fully welded of high-strength steel, the UltraCut Series 3 cutting deck features Exmark’s exclusive Flow-Control baffles for Exmark Signature cut quality. Maintenance-free sealed bearing spindle assemblies and double-capture anti-scalp rollers offer increased durability with reduced maintenance requirements.
Integrated Hydro Pumps and Motors
Dual Hydro-Gear ZT-3100 hydro transmissions feature an integrated pump and motor design for maximum efficiency, long-term reliability and ground speeds of up to 9 mph.
High-Strength Fabricated Steel Frame
Fabricated and fully welded of high-strength rectangular steel tubing, the Radius frame places the heaviest components –– engine, transmission and fuel tank –– low and centralized in the frame. This lowers the machine’s center of gravity for increased traction and stability. New steel engine guards increase engine protection at the sides and rear of the machine, while also being easily removable for service access.
Easy Serviceability
With a floor pan and belt shields that remove easily, without tools, and an integrated jack receiver at the front of the frame, Radius models offer unparalleled maintenance access to the top and bottom of the cutting deck.
Upgraded Commercial Warranty
Radius S-Series models are covered by an extended 4-year/500-hour commercial warranty.
