Exmark Radius S-Series 48

If you've got three to five acres to maintain and want to reclaim your weekends, the Exmark Radius S-Series delivers the cut quality and efficiency of a commercial mower at a price point that makes sense for serious property owners.

The 23 HP Kawasaki FR691 engine is a proven workhorse — not a consumer-grade motor dressed up with badges. Paired with hydro-drive transmissions, the Radius S-Series pushes through thick Pacific Northwest grass at up to 9 MPH, covering up to 3.48 acres per hour. That's the difference between a half-day job and a quick morning run.

The 48" UltraCut Series 3 deck is where the cut quality comes from. Sealed, non-greasable spindles mean less time on maintenance and more time mowing. The 7.75"-diameter cutter housing is built with the kind of steel thickness you'd expect from professional-grade equipment.

Exmark didn't cut corners on the seat. The deluxe two-tone bolstered suspension seat with flip-up armrests and 3" of travel absorbs the kind of bumps you get on uneven Pacific Northwest terrain — tree roots, ruts from wet seasons, the occasional gopher mound. Combined with 23" drive tires, the ride is noticeably smoother than what you'd get on a standard residential machine.

Standard features include an hour meter to track service intervals, a hitch for towing attachments, and a cup holder — small details that matter on a long mowing day. Cutting height adjusts from 1.5" to 5.0" to handle everything from a tight lawn to rough pasture edges.

Two annual grease points. That's it for routine lubrication. The HydroGear transmissions are designed for serviceability — not sealed and throw-away like some consumer units. The 7-gallon fuel tank means fewer stops to refuel mid-job. This is a mower designed to run for years with straightforward maintenance.

Ideal For:

• Properties of 3–5 acres with regular mowing needs
• Operators who want commercial cut quality without a commercial price tag
• Hobby farmers and large residential properties
• Those who've outgrown their riding tractor and want real efficiency
