Radius S-Series Features
UltraCut Deck Technology
Exmark’s exclusive UltraCut decks are featured on Radius models in a choice of 44- to 60-inch cut widths. 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 Unibody Frame
Fully-welded using 2-inch by 3-inch frame tubes, the Radius frame design places major components including the engine, hydro drive and fuel tank lower, with better mass centralization. This gives the Radius increased hillside traction and stability, with heightened maneuverability.
Quick Adjustable Rollover Protection System (ROPS)
Uses an easy-to-fold up-and-down design built from round tubes and provides flexibility for placement of accessories.
Height of Cut Made Easy
The patented height of cut system is a user friendly tool developed for operators to quickly and accurately select the height of cut.
