FEATURES AND BENEFITS

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

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

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 1.25 and 5.0 inches and controls deck lift functions using a single switch.

WARRANTY

Commercial Use: 3-year unlimited hours; limited warranty: First two years covering parts and labor; last year covering parts only. Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

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

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

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.

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.

LED WORK LIGHTS

LED work lights provide improved visibility in low light situations.

SUNSHADE CANOPY ALUMINUM

Diamond-plated aluminum canopy is highly resistant to abrasions. Easily mounts to ROPS to increase operator comfort by limiting exposure to direct sunlight and reducing eye strain.
