Powerful performance and fuel economy are available with the 337G5.

Equipped with a Briggs & Stratton Vanguard Electronic Fuel-Injection (EFI) vertical shaft, V-twin engine continuously adjusts fuel ratios while using less fuel. EFI technology minimizes fuel-related services issues and offers reduced emissions.

B & S Vanguard Electronic Fuel Injection (EFI Engine) Engine

  • 37 Horsepower Briggs & Stratton Vanguard V-Twin - 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

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.

    Hydro-Gear ZT-5400 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.
