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.
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
Quik Ajust 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.
