Single-fork Tail Wheel 

  • Single-fork tail wheels enhance weight distribution, improve stability and enhance castering effect when maneuvering.


QuikConverter™ Implement Capability 

  • Add or remove implements in minutes without tools with QuikConverter™ Implement System
  • Equip your out-front mower with a wide range of tools, including turf cleanup, renovation and snow removal implements that extend your productivity year-round


Exclusive T-Drive™ Transmission 

  • Tandem 12cc Parker pumps-in-reservoir transmission is specifically designed for turf-care applications
  • In-line CoolFan™ cooling system and integrated, replaceable, high-efficiency fine-particle filter
  • Design directs more power to the cutting deck as power-sapping components are eliminated


AntiVibe Power Platform® 

Isolates the engine and T-Drive™ from the operator platform for an unprecedented vibration-free experience

Minimal Maintenance 

  • Fewer than 10 grease points and easy top-side access to belts and filters
  • 1,000-hour transmission fluid change intervals
  • Self-tensioning belts minimize cost and labor on routine maintenance


Built for Long Life 

  • Robotically-welded, high-grade steel construction and I-beam reinforcement for long-lasting durability
  • Centered-bearing design provides greater load-bearing capacity to easily handle the weight of operator, fuel and high-capacity collector with reserve strength for curb shocks and weight shifts
  • Tough-as-nails powder-coated finish is fusion-bonded for chip and rust resistance


Kohler Command Pro Engine 

  • 694 cc, 2-cylinder, air-cooled Kohler Command V-Twin engine


PowerFold® Electric Deck Lift 

Standard on all FrontMount™ DuraMax® decks, PowerFold® is the zero-turn mower industry's first electric deck lift (introduced in 2004).

PowerFold® rotates the deck nearly 90 degrees to provide easy access to the underside of the deck for simplified maintenance and mulching package installation, plus space-saving portability and storage.

The feature also adjusts cutting height between 1.25 and 5.0 inches and controls deck lift functions using a single switch.

Heavy-duty Deck 

  • Extra-deep, 5.5-inch deck is fabricated from heavy-gauge formed steel with a reinforced anvil edge
  • Specially designed cutting chambers enhance airflow for better cut quality
  • Deck easily converts from side discharge to optional Down Discharge™ mulching or PowerVac™ collection
  • Sentry™ spindles with massive, 8-inch flanges anchored in a 6-bolt pattern, spread the force of impact for greater strength
  • Spindle planes are fabricated from double-layered formed steel laminate and combine with the spindles to form a triple-strength deck to keep blades level and deliver a high-quality cut.
  • Sentry™ spindle guards shield spindle housing and seal lower bearings from fiber wrap and dirt ingestion


Vigilant Operator Presence System™ 

  • Standard, low profile operator protection structure (OPS) with an adjustable seatbelt
  • Dampened steering levers that return to neutral from forward and reverse
  • Interlock switches that shut down the engine when the operator leaves the seat while PTO is engaged or levers are in drive position


Ultimate Operator Station™

  • The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and armrests are covered in scuff-resistant, breathable CoolTemp Cordura® fabric, which dissipates heat and won’t tear or crack with extended use.
  • Operational controls including throttle, ignition and push/pull PTO switches, angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach.
  • One- or two handed operation with QuikAjust Tilt™ dual levers with 9-inch comfort range to custom fit operator's reach. Levers automatically return to neutral from either forward or reverse position and are less strenuous than riding mowers with steering wheels.
