Exmark Radius S Series RZS730GKA603A3 UltraCut Deck Technology

Exmark’s exclusive UltraCut decks are featured on Radius models. Every UltraCut cutting deck features Exmark’s exclusive maintenance-free, sealed-bearing spindle assemblies for increased durability and reduced downtime, combined with zero maintenance.

Exmark Radius S Series RZS730GKA603A3 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.

An adjustable ROPS system is easy to fold up-and-down, and is built from round tubes for easy, flexible accessory placement.

Exmark Radius S Series RZS730GKA603A3 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.
