Model 337G5 EFI 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.
