*Actual results may vary.

Designed for fuel efficient performance while maximising power to meet the demands of daily operation, the Model 721DT provides economy, speed, durability and versatility for any application.

Features

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 fabricated from double-layered, 7-gauge plus 10-gauge formed steel laminate that is 0.3138 inch thick 25.5 percent thicker than ½-inch steel
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.

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.

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
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.

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.

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

LED WORK LIGHTS
LED work lights provide improved visibility in low light situations.

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
