Features may include:

Adjustable Rollover Protection System (ROPS)

New square tubing rollover protection system (ROPS) is easily foldable for storage.

Height of Cut Made Easy

Exmark’s patented cut height adjustment system is very easy to use, enabling the user to quickly set height of cut with unmatched accuracy, right from the operator seat.

High-Strength Steel Frame

Fabricated and fully welded of high-strength rectangular steel tubing, the Radius frame places the heaviest components –– engine, transmission and fuel tank –– low and centralized in the frame. This lowers the machine’s center of gravity for increased traction and stability. New steel engine guards increase engine protection at the sides and rear of the machine, while also being easily removable for service access.

Series 2+ Cutting Deck

Fabricated and fully welded from high-strength steel, the Exmark Series 2+ cutting decks feature maintenance-free sealed bearing spindle assemblies and durable double-capture anti-scalp rollers to deliver the cut quality and durability you expect from Exmark.

Integrated Hydro Pump and Motor Design

Dual HydroGear ZT-2800 hydro transmissions feature an integrated pump and motor design for maximum efficiency, long-term reliability and ground speeds of up to 8 mph.

Large Drive and Caster Tires

Radius E-Series models are equipped with large, smooth-riding 22-inch drive tires and 13-inch caster tires.
