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.
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.
SERVICE MADE EASY: The floor pan and belt shields remove easily without tools, making it easier to access the belts and top of the cutting deck for maintenance. Plus, a standard welded jack receiver on the Radius frame enables easier service of the underside of the deck when combined with the optional jack.
SIDE PODS: The side pod design places the most important controls right at the operator’s fingertips, for easy operation with a minimum of necessary movement.
UPGRADED CASTERS: 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.
