Features
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
Vigilant Operator Presence System™
- Standard, low profile Roll-over Protection System (ROPS) structure 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
Wide Stance Single-Fork Tail Wheels
- Wide stance single-fork tail wheels provide increased flotation and stability for a smoother ride.
Ultimate Operator Station®
- ComfortZone™ seat eliminates jostles and jolts with coil-spring suspension and a fully padded, high-back seat, padded armrests and variable density foam cushion. Iso-mounting smooths the ride, erases fatigue and keeps the operator comfortably in control at faster mowing speeds
- Operational controls including throttle, choke and 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.
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
PowerFold® Electric Deck Lift
- Standard on all FrontMount™ DuraMax® decks 48-inch and larger, 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 1.0 and 5.0 inches and controls deck lift functions using a single switch.
High Temperature Clutch Cut Out
- Equipped with a High Temperature Clutch Cut-Out that automatically disengages the PTO if engine temperature reaches a certain point to prevent engine damage
Kubota Diesel Engine
- EPA Tier 4 Final-compliant 44 cu. in. (719 cc), 3-cylinder, liquid-cooled Kubota Clean Diesel engine with horizontal crankshaft and pressure lube for smooth, reliable operation
