Features
UltraCut Series 4 Cutting Deck
Fabricated and fully welded of high-strength steel, the UltraCut Series 4 cutting deck features Exmark’s exclusive Flow-Control baffles for Exmark Signature cut quality. Maintenance-free sealed bearing spindle assemblies and upgraded double-capture anti-scalp rollers offer increased durability with reduced maintenance requirements.
Kawasaki Commercial Engines
Radius X-Series takes commercial power and performance to the next level with premium Kawasaki V-twin engines.
High-Back Suspension Seat
Radius X-Series features a deluxe high-back operator seat with three inches of adjustable suspension, plus an EVC stretch foam base and iso mounts at the seat base for superior all-day mowing comfort.
Heavy-Duty 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.
Upgraded Caster Assemblies
Radius X-Series models feature upgraded caster assemblies featuring maintenance-free tapered caster pivot bearings, with cast steel caster forks and large, semi-pneumatic caster tires.
