Exmark redesigns Radius E- and S-Series zero-turn mowers

Exmark unveiled redesigned 2026 Radius E- and S-Series zero-turn mowers this week at the Equip Exposition trade show in Louisville.

The new models take inspiration from the 2025 redesign of Exmark’s premier Lazer Z models.

“These new Radius models are perfect for users looking for maximum cut quality and long-lasting performance,” says Exmark Marketing Manager, Lenny Mangnall. “With up to 60-inch cutting decks and powerful Kawasaki FR series engines, the new Radius models make quick work of properties of up to five or six acres.”

Exmark's 2026 Radius E-Series zero-turn mower

The 2026 Radius E-Series features a new Exmark Series 2+ cutting deck in a choice of 48-, 54- or 60-inch cutting widths. The cutting deck is fabricated and fully welded of high-strength steel, with maintenance-free sealed bearing blade spindles. Exmark’s Adapt system is available as an accessory. Adapt enables quick, tools-free deck rake adjustments from the operator seat, so the operator can tailor deck performance for specific turf types and cutting conditions.

The mowers also feature the integrated hydro pump and motor design of the HydroGear transmission and ground speeds of up to eight miles per hour.

Exmark's Radius S-Series zero-turn mower

The new Radius S-Series features Exmark’s UltraCut Series 3 cutting deck, with available Adapt tools-free deck rake adjustment as an accessory. Fabricated and welded of high-strength steel, with a 10-gauge top and 7-gauge steel skirts, the UltraCut Series 3 cutting deck offers higher capacity.

When combined with the higher capacity HydroGear ZT-3100 transmission, the Radius S-Series can mow at speeds of up to 9 miles per hour. 23-inch drive tires and a deluxe suspension seat reduce bumps and vibrations that reach the operator.

Both new Radius models feature premium air-cooled Kawasaki V-twin gasoline engines. All 48- and 52-inch Radius E- and S-Series models feature the FR691V powerplant, while 60-inch models are equipped with the FR730V to better manage the load of the larger cutting deck.

Exmark's Radius X-Series zero-turn mowers

The premium Radius X-Series model continues into 2026 with minor changes. The Radius X-Series features an UltraCut Series 4 cutting deck in a choice of 52- or 60-inch cut widths, with Exmark’s Adapt tools-free deck rake adjustment available as an accessory. More powerful Kawasaki engines, stronger MagStop PTO clutches and higher-capacity HydroGear transmissions deliver increased cutting performance and forward speeds of up to 10 miles per hour.

52-inch Radius X-Series models are equipped with the Kawasaki FX801V V-twin, while 60-inch models upgrade to the powerful 999cc FX921V. Both engines feature high-capacity cyclonic air filtration and pressurized lubrication for maximum durability. A deluxe high-back suspension seat with padded armrests is fully adjustable to accommodate virtually any operator.

All 2026 Radius models feature a fabricated and welded frame built of high-strength rectangular section tubular steel. Steel engine guards increase engine protection at the sides and rear of the machines. The guards are easy to remove for service. A seven-gallon single fuel tank provides extended runtime between fill-ups.

Radius models feature just two annual grease points, plus the floor pan and belt shields can be removed easily without tools to ease access to the belts and top of the cutting deck. A standard jack receiver makes under deck maintenance quick and easy as well.
