Series 300G

The 328G4 EFI and 337G5 EFI contain Briggs & Stratton® Vanguard EFI engines designed with a vertical crankshaft and pressure lubrication system, allowing each machine to run cooler while also providing a longer service life. The Delphi-based closed-loop EFI engine design continually adjusts the fuel ratio to use less fuel and provide reliable hot and cold starts, reducing the overall exhaust emissions and limiting fuel-related service issues. Where the two engines differ is power capacity. The 328G4 EFI is fit with an 810 cc V- Twin model while the 337G5 EFI features the more powerful 993 cc V-Twin model.

Grasshopper extra-deep 5.5” decks are made from heavy-gauge formed steel and reinforced with an anvil leading-edge. Complete with specially designed cutting chambers to enhance airflow, our decks also contain Sentry™ spindles with 8-inch flanges anchored in a 6-bolt pattern. The formed steel spindle planes are fabricated from double-layered steel laminate and combine with the spindles to form a triple-strength deck that is nearly 1-inch thick in stress zones. Grasshopper decks are built to keep the blades level and deliver a high-quality finish every #MowDay.

Our low profile Rollover Protection System (ROPS) comes with an adjustable seatbelt, dampened steering levers that return to neutral from both forward and reverse, and interlock switches that shut down the engine immediately if the operator leaves the seat while the PTO is engaged or the steering levers are in drive position.

The 300G Series MidMount mowers feature G4 Hydro-Gear transmissions that are designed to provide powerful, smooth response. The transmissions contain heavy-duty, self-contained commercial transaxles that are integrated with a cooling fan and feature 1-3/8-inch axles for longer service life. Not to mention, their best-in-class transmission fluid change intervals will help reduce costs and cut down on maintenance time.

With the QuikAjust® DropPin™ Height Adjustment raising and lowering the deck of your mower has never been more convenient. Easily adjust your deck’s height anywhere from 1 to 5 inches with a single foot pedal and drop pin for ultimate precision and a smoother finish.

Both mowers in the 300G lineup have just five Access-Eze™ lubrication points and are equipped with self-tensioning belts, helping to cut down on maintenance time by 80% and make your day-to-day mowing operations easier.

The Ultimate Operator Station on the 300G Series mowers are equipped with either the deluxe Premium Comfort Seat or the Grammar Premier Suspension Seat. Both seats offer unmatched comfort and feature scuff-resistant, CoolTemp Cordura® fabric, padded lumbar support, and foldable armrests. Additionally, the operational controls, including the throttle, ignition, choke, and more are all well positioned for visibility and ease of reach

All 300G series MidMount riding lawn mowers are constructed from robotically-welded, formed steel and built to last decades. Engineered with a centered-bearing design that provides greater load-bearing capacity, these mowers can handle the weight of the operator, fuel, and high-capacity collector with ease. The 300G series is complete with a tough-as-nails powder-coated finish that is fusion-bonded—ensuring these models will resist rust, chips, and whatever else nature throw its way.

Standard across all 300G mowers, these steering levers offer an easy nine-inch range of adjustment, allowing operators of all shapes and sizes to maintain a natural wrist position during long hours of mowing.
