Grasshopper 328G4 EFI
300G Series 328G4 EFI
Overview:
Power, efficiency and economy. The 328G4 is equipped with a vertical crankshaft Electronic Fuel Injection (EFI) Briggs & Stratton Vanguard engine that continuously adjusts fuel ratios while using less fuel. EFI engines provide reliable hot and cold starts, reduce emissions and minimize fuel-induced service issues.
Features
B & S Vanguard Electronic Fuel Injection (EFI Engine) Engine
- 810cc 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
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 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.
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
Ultimate Operator Station™
- The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support with sliding 2-inch fore and aft adjustment for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and foldable 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.
