Features & Benefits

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.
QUIKAJUST 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.
QUIKAJUST® 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.
REDUCED MAINTENANCE: Only two Access-Eze™ lubrication points cut maintenance time up to 95%. Self-tensioning belts minimize cost and labor on routine maintenance.
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.
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.
B & S VANGUARD ELECTRONIC FUEL INJECTION (EFI ENGINE) ENGINE: 993cc V-Twin Briggs & Stratton Vanguard Electronic Fuel Injection (EFI). OHV gasoline engine with vertical crankshaft and pressure lube run cooler and provide longer service life. Delphi-based closed-loop EFI engine continually adjusts fuel ratio to use less fuel and provide reliable hot and cold starts, reduced exhaust emissions and fewer fuel-related service issues. Automotive-style plug-in diagnostics. Facilitates faster and more precise service.
PREMIER SUSPENSION SEAT: Optional premier suspension seat provides the ultimate in operator comfort. Low-profile seat slides fore and aft and includes an integrated shock absorber that manually adjusts to operators between 100 – 300 lbs. Other ergonomic features include a backrest that tilts from -5 degrees to +30 degrees, a lumbar support mechanism, adjustable armrests and a retractable seat belt.
HYDRO-GEAR ZT-4400 TRANSMISSION: The G5 Hydro-Gear ZT-5400 transmissions are designed to provide powerful, smooth response. The heavy-duty, self-contained commercial transaxles are integrated with a cooling fan and feature 1-3/8-inch axles for longer service life. You’ll also enjoy best-in-class transmission fluid change intervals after a 100-hour break-in period, reducing costs and maintenance time.
LED WORK LIGHTS: LED work lights provide improved visibility in low light situations.
ULTIMATE OPERATOR STATION™: The Grammer Premier Suspension Seat is covered with breathable CoolTemp Cordura® fabric which dissipates heat and won’t tear or crack. This seat offers the ultimate in customized operator fit. It adjusts to the individual operator’s weight and slides fore and aft. The backrest tilts and includes adjustable lumbar support. Adjustable, foldable, padded armrests complete the comfort features of this seat. QuikAjust Tilt™ dual levers with 9-inch adjustment and the adjustable seat work together to provide a custom fit for operators of all sizes. 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.
