If you’re looking for the power and productivity of a premium commercial mower on a budget, you’re looking for a Radius X-Series. It combines features proven on our premier machines with the unbeatable value and efficiency you’ve come to expect from the Radius.
Choose from 52- or 60-inch UltraCut Series 4 cutting decks, both with powerful Kawasaki commercial engines –– a FX801 on the 52-inch, and a FX921 on the 60-inch. The integrated Hydro-Gear transmissions work with aggressive 24-inch Kenda drive tires to provide unmatched traction and control, with forward speeds of up to 10 mph. Large semi-pneumatic caster tires, cast steel caster forks, and tapered caster pivot bearings provide years of maintenance-free performance. And with an adjustable full-suspension operator seat and isolated floor pan, the Radius X-Series makes “mow time” more enjoyable.
Looking for more power, larger cutting decks and cutting-edge productivity and efficiency? With cutting decks of up to 144-inches wide, our Lazer Z line is as good as it gets.
Radius X-Series Features
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.
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.
New Side Pods
The new side pod design places the most important controls right at the operator’s fingertips, for easy operation with a minimum of necessary movement.
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.
