Exmark has expanded its 2021 zero-turn riding mower offering with a new Radius E-Series machine featuring a twin-blade 48-in. UltraCut Series 3 cutting deck.
Exmark Product Manager, Mike Mayfield, said the new mid-size Radius E-Series model offers a number of benefits, including increased cut quality, improved mulching and more uniform clipping discharge.
“Radius E-Series mowers deliver professional quality results paired with unmatched value,” Mayfield said. “The new 48-in. UltraCut Series 3 twin-blade cutting deck uses longer blades than an equivalent three-blade cutting deck, for increased cutting system performance, particularly when mulching or bagging.”
The design of the twin-blade cutting system increases cutting chamber volume by 50%. The larger cutting chamber reduces deck packing, with more efficient tranfer of clippings from the left to right chamber in side-discharge use.
The new UltraCut Series 3 twin-blade cutting deck is fabricated and welded from 7- and 10-gauge high-strength alloy steel. Heavy-duty Series 4 cutting spindle assemblies feature sealed bearings for maximum durability with reduced maintenance requirements.
The new Radius E-Series machine is powered by a Kawasaki FR691V air-cooled twin-cylinder engine, featuring pressurized lubrication and cast-iron cylinder liners. Exmark’s hydro drive system uses dual Hydro Gear hydros to deliver zero-turn precision and infinitely variable ground speeds of up to 8.0 mph forward and 5.0 mph reverse.
