Exmark has expanded its 2021 zero-turn riding mower offering with a new Radius E-Series machine featuring a twin-blade 48-inch UltraCut Series 3 cutting deck. The new mid-size Radius E-Series model offers increased cut quality, improved mulching, and more uniform clipping discharge.

The design of the twin-blade cutting system increases cutting chamber volume by 50%. The larger cutting chamber reduces deck packing, with more efficient transfer 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 mph forward and 5 mph reverse.
