What It Is

These Gator mulching blades (OEM cross-ref 131-4547-03 / 108-9764-03) are designed to cut grass clippings into fine particles and recirculate them into the turf for natural fertilization. They fit Toro riding mowers with a 22-inch cutting deck, replacing standard blades to improve mulching performance on medium to large lawns.

Fitment & Compatibility

Before buying, confirm:

• Deck size: Only for 22-inch Toro riding mower decks (e.g., TimeCutter, Titan, or similar models with a 22” fabricated or stamped deck).
• Model cross-ref: Replaces OEM part numbers 10654, 10655, 10656, 104-8697-03, and 108-9764-03P. Check your mower’s manual or current blade part number.
• Measurements: Blade length is approximately 22 inches overall, with a 5-point star center hole and 1-inch diameter spindle mount. Measure your existing blade’s length and center hole shape before ordering.
• Not compatible with 21-inch or 24-inch decks, push mowers, or zero-turn mowers with a different spindle pattern.

Key Things to Know

• Quality: Gator blades are made from hardened steel with a mulching wing design that creates a vacuum to lift grass for finer cutting. They’re durable but may wear faster in sandy soil.
• Installation: Easy DIY job with basic tools (socket wrench, blade removal tool). Torque to 55–65 ft-lbs. Use thread locker on spindle bolts if recommended by your mower manual.
• Common gotcha: The blades are marked “this side up” – install with the wings pointing upward toward the deck. Reversing them will cause poor cut and potential vibration.
• Performance: Best for dry grass; wet or thick grass may clump under the deck. Clean the deck regularly for optimal mulching.

Should You Buy It

If you own a Toro 22-inch riding mower and want better mulching than OEM blades provide, this is a solid upgrade. The fine cut reduces bagging frequency and feeds your lawn naturally. Skip it if you mostly bag clippings or mow wet, tall grass – standard lift blades will work better.
