2025 Grasshopper MidMount™ 300G Series 328G4 EFI 52"

Information

2025 Grasshopper MidMount™ 300G Series 328G4 EFI 52"

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 may include:

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
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
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.
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.
