Oregon 96-628 Gator G3 Lawn Mower Blade, 28-Inch, Replaces Murray

What It Is

The Oregon 96-628 Gator G3 is a 28-inch mulching blade designed for high-lift air flow to cut, shred, and recirculate grass clippings into fine particles. It’s intended for zero-turn and riding mowers with 28-inch decks, commonly used on Murray and other universal-fit models.

Fitment & Compatibility

• Deck size: Must be exactly 28 inches. Measure the blade length from tip to tip (center hole to center hole is not enough).
• OEM vs aftermarket: This is a universal replacement for Murray, but also fits many Craftsman, Husqvarna, and MTD models. Check your mower’s blade part number against Oregon’s cross-reference guide.
• Key measurements: Center hole diameter is 1-inch (round) with a 5-point star pattern. Blade thickness is 0.203 inches. Verify these match your spindle.
• What to check before buying: Confirm the blade’s offset (lift height) matches your deck’s design. The G3 has a medium offset; low-deck mowers may need a different blade.

Key Things to Know

• Quality: Made from heat-treated boron steel with a hardened edge. Holds up well against rocks and roots but will dull faster than standard blades if used in sandy soil.
• Installation: Easy if you have a torque wrench—tighten to 70-90 ft-lbs. The star pattern centers the blade, but you’ll need a blade removal tool for stubborn bolts.
• Common gotcha: These blades are heavier than OEM (about 1.2 lbs each). This can strain a weak spindle bearing or cause vibration if not balanced. Always balance after install.
• Performance: Excellent for mulching thick, wet grass; produces fine clippings that decompose fast. Not ideal for bagging or side-discharge—you’ll lose some air velocity.

Should You Buy It

Buy this if you want premium mulching performance on a 28-inch deck and your mower’s spindle can handle the extra weight. It’s a solid upgrade over standard blades for homeowners with large, thick lawns. Skip it if you primarily bag or have a low-clearance deck.
