Features & Benefits
- KOHLER CONFIDANT ENGINE: Professional-grade 747 cc Kohler Confidant OHV V-Twin engine Designed to maximize airflow and reduce operating temperatures for extended service life Heavy-duty cyclonic air filter with Quad-Clean™ multi-stage air filtration Full-pressure lubrication to protect critical components
- HYDRO-GEAR ZT-4400 TRANSMISSION: The G4 Hydro-Gear ZT-4400 transmissions are designed to provide powerful, smooth response The heavy-duty, self-contained commercial transaxles are integrated with a cooling fan and feature 13/8-inch axles for longer service life.

- 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
- QUIKADJUST DROP PIN HEIGHT ADJUSTMENT: Raise and lower the deck easily with foot pedal and drop pin for precision cutting heights between 1.0 and 5.0 inches.
- WARRANTY: Commercial Use: 2-year or 800-hour (whichever comes first); limited warranty covering parts and labor. Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.
- RUGGED CONSTRUCTION: Robotically-welded steel construction for long-lasting durability Centered-bearing design provides greater load-bearing capacity to 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
- REDUCED MAINTENANCE: Only two Access-Eze™ lubrication points cut maintenance time up to 95% Self-tensioning belts minimize cost and labor on routine maintenance
- 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
- QUIKADJUST TILT LEVERS: QuikAjust Tilt™ steering levers with "no tools" adjustment provide a 9-inch range for maximum comfort and fit while maintaining natural arm and wrist positions.
- ULTIMATE SUSPENSION RIDE SEAT: Deep-cushioned, high-back, foam-padded, scuff-resistant Cordura®-covered seat with padded lumbar support and armrests Roomy, iso-mounted, shock-absorbing footrest
- 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 ComfortReach™ adjustable Hydra-Smooth™ dual levers that automatically return to neutral from either forward or reverse position.
