Discover the Exmark Radius E-Series Mower

With the performance you expect from Exmark, new features and a fresh new look, the Radius E-Series is the right choice for home and acreage owners looking for a commercial-grade mower without breaking the bank. Choose from 48-, 54-, or 60-inch Exmark Series 2+ cutting decks and a wide range of available accessories for maximum versatility. And with new Kawasaki V-twin engine options, Radius E-Series models deliver more performance per dollar than ever before. Check out the Radius S-Series and Radius X-Series models if you’re looking for even more features and productivity. (RD models coming in 2026.)

Features may include:

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.
Adjustable Rollover Protection System (ROPS)
  • An adjustable ROPS system is easy to fold up-and-down, and is built from round tubes for easy, flexible accessory placement.
Height of Cut Made Easy
  • Our patented height of cut adjustment system is user friendly and allows the operator to quickly and accurately select height of cut from the operator seat.
Large Tires
  • Radius E-Series models feature smooth rolling 22-inch drive tires and large, 13x6.5-inch caster tires.
