KUBOTA MAXTORQUE™ DIESEL ENGINE
1.3l, 3-cylinder, liquid-cooled Kubota MaxTorque™ diesel engine with horizontal crankshaft and pressure lube for smooth, reliable operation
DESIGN-MATCHED G2 TRANSMISSION
Rugged G2.1 transmission with auxiliary cooling fans, HydroGear variable displacement 21 cc piston-type pumps and high-torque Parker wheel motors CoolFan™ hydro cooling system with 7-micron absolute filter for cooling efficiency Delivers smooth response and requires less maintenance, with industry-leading 1,000-hour fluid change interval
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
SPLINE SHAFT PTO
Delivers more power more efficiently to the cutting deck or implement with more surface-to-surface contact while extending shaft longevity
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 1.25 and 5.0 inches and controls deck lift functions using a single switch.
HYDRAULIC DECK LIFT
Raises the front of the deck to maneuver over soft or uneven ground and to clear curbs, trailer ramps and other obstacles. Lift switch is standard in lever on current models. Kit includes Universal Wiring Harness and requires 50-lb. counterweight and counterweight mount kit.
WARRANTY
Commercial Use: 3-year unlimited hours; limited warranty covering parts and labor. Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.
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
ULTIMATE OPERATOR STATION®

ULTIMATE OPERATOR STATION®
Operational controls including throttle, choke and angled View-Eze™ console, two USB charging ports sand adjustable cup holder are well positioned for visibility and ease of reach
ULTIMATE OPERATOR STATION®
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.
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.
QUIIKCONVERTER™ 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
LED WORK LIGHTS
LED work lights provide improved visibility in low light situations.
ADJUSTABLE CUP HOLDER
The Adjustable Cup Holder locks into multiple positions to accommodate a wide range of drink sizes.
FILTER MINDER KIT
The Filter Minder alerts the operator when airflow is restricted in the air canister on dual-element air filters.
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
PREMIER SUSPENSION SEAT
The optional Premier Suspension Seat offers the ultimate in comfort and an extra measure of suspension while mowing over rough ground. Adjustable backrest, armrests and lumbar support with weight-adjusted suspension control provide maximum comfort for operators of all sizes and preferences.
WIDE SEAT CONVERSION KIT
Provides additional seating room for larger operators or to accommodate cell phones or pagers. Requires seat belt extension.
EXTENDED STEERING LEVERS
Provides an additional two inches of leg clearance
FOLDABLE ROPS
The Foldable ROPS allows the two-post ROPS to be lowered for mowing under low-hanging trees and other overhead obstacles, or for storing and transporting in enclosed trailers with low door clearance. CAUTION: Avoid drop-offs, embankments and steep slopes. Do not allow ROPS to provide a false pretense of security in hazardous areas and avoid questionable conditions. Always wear seatbelt when Foldable ROPS is in up-right position. When Foldable ROPS is down, DO NOT use seat belt, and drive with extra caution.
SIDE DISCHARGE CONTROL KIT
Control the discharge of the mower deck to avoid putting clippings in flower beds and on sidewalks
TURF TREAD TIRES
Turf Tread Drive Tires provide overall excellent performance on level mowing areas.
TAIL WHEEL OPTIONS
Dual-fork tail wheels or wide stance single-fork tail wheels.
SUNSHADE CANOPY VINYL
Lightweight, water repellent, UV-resistant vinyl canopy mounts easily to OPS or ROPS to limit exposure to direct sunlight, reducing eye strain and increasing operator comfort.
YELLOW BEACON LIGHT
Yellow beacon attaches to OPS or ROPS to provide greater visibility in high-traffic areas.
RADIATOR CLEANING WAND
A multi-channel sprayer that combs water pressure between radiator fins without damage, dislodging packed-in dust and debris that can become an invisible source of engine overheating. Remove and clean radiator screen regularly. A dirty screen will cause the engine to overheat. For use on liquid-cooled models only.
