6PK Oregon G6 Gator Mulching Blades 396-726 fits Ariens 00273100 03253800 03399704 04916400, Gravely 00450300 04916400 4916400 00273100

What It Is

This is a 6-pack of Oregon G6 Gator mulching blades (model 396-726) designed for zero-turn and riding mowers with 50–54-inch decks. They replace OEM blades on Ariens and Gravely commercial models, converting standard cutting to fine mulching for bagging or side-discharge reduction.

Fitment & Compatibility

• Deck size: Fits 50" and 54" decks only—measure your deck width before ordering. Not for 42", 48", 60", or 72" decks.
• OEM part numbers: Ariens 00273100, 03253800, 03399704, 04916400; Gravely 00450300, 04916400, 4916400, 00273100. Cross-reference your blade part number under the deck or in your manual.
• Aftermarket check: Oregon G6 is an aftermarket replacement, not OEM. It uses the same center hole diameter (typically 1" or 7/8") and offset. Measure your existing blade’s length and hole size if unsure.
• Blade count: 6 blades total (3 per spindle or 2 per spindle on a 3-spindle deck). Verify your deck uses 6 blades (common on 54" decks) or 3.
• Spindle compatibility: Fits standard Ariens/Gravely spindles—no adapter needed. Check for bent spindles before installing.

Key Things to Know

• Mulching performance: The G6 Gator design has six cutting surfaces and a curved wing for finer clippings. Works best with dry, short grass—wet or tall grass may clog.
• Installation: Easy swap if you have a torque wrench (tighten to 40–50 ft-lbs). Use blue Loctite on spindle bolts to prevent loosening. No balancing required out of box, but check for wobble after first use.
• Durability: Oregon blades are heat-treated and last 1–2 seasons on residential use. Commercial mowing may require replacement every 25–30 hours. Not for rocks or debris—can chip or bend.
• Common gotcha: The 6-pack includes blades only, not bolts or washers. Reuse your original hardware if in good condition, or buy new OEM bolts separately.

Should You Buy It

If you own a 50–54" Ariens or Gravely zero-turn and want fine mulching without buying OEM, this 6-pack is a cost-effective upgrade. Best for homeowners with average lawns—skip it for heavy commercial use or if you need a standard lift blade for bagging.
