Features
B&S Vanguard Big Block
- 896 cc, air-cooled OHV Vanguard Big Block V-twin engine with horizontal crankshaft for longer life
Design-Matched G2 Transmission
- Robust G2 transmission features 7-micron absolute filter and CoolFan™ hydro cooling system
- HydroGear variable displacement 16 cc piston-pumps and high-torque Parker wheel motors
- Provides 1,000-hour transmission 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
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
Ultimate Operator Station™
- The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and armrests are covered in scuff-resistant, breathable CoolTemp Cordura® fabric, which dissipates heat and won’t tear or crack with extended use.
- 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.
