QWD 108-9764-03 Mower Blade for Toro 22 Inch Recycler Lawn Mower, Replacement for 131-4547-03, 104-8697-03, Mulching Toothed Blade for Toro 22" Steel Deck Mowers

What It Is

This is a mulching toothed blade designed for Toro 22-inch Recycler lawn mowers with steel decks. It replaces OEM part numbers 131-4547-03 and 104-8697-03, and is intended to cut grass into fine clippings for nutrient recycling rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size: Only fits 22-inch Toro Recycler mowers with a steel deck (model year 2015 and later typically). Does not fit aluminum deck models.
• OEM cross-reference: Direct replacement for Toro part numbers 131-4547-03 and 104-8697-03. Confirm your current blade’s part number matches one of these.
• Measurements: Blade length is 22 inches, center hole diameter is 1 inch, and it has a 5-point star drive (not a standard hex or round hole). Measure your existing blade’s length and hole shape before ordering.
• Model check: Works on Toro Recycler models 20351, 20352, 20353, 20370, 20371, 20378, 20379, and similar steel-deck 22-inch units. Verify your model number on the mower’s sticker under the seat or on the frame.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and a torque wrench (recommended torque: 55-65 ft-lbs). The star drive center hole can be finicky if the bolt is corroded—use penetrating oil if stuck.
• Mulching performance: The toothed design creates a vacuum that lifts grass for finer cuts. Works best with dry, short grass (under 3 inches). Wet or tall grass may clog.
• Durability: Aftermarket blade, but made from heat-treated steel. Expect similar lifespan to OEM (about 25-30 hours of mowing before dulling). Sharpening is possible, but the teeth make it harder than a straight blade.
• Common gotcha: Some users report the blade is slightly thicker than OEM, which can cause a vibration if the mower’s spindle shaft is worn. Check for play in the blade adapter before installing.

Should You Buy It

Buy this if you own a Toro 22-inch Recycler with a steel deck and want a direct, cost-effective replacement for the OEM mulching blade. It’s a solid choice for homeowners who prioritize fine clippings and don’t bag. Skip it if you have an aluminum deck or need a standard lift blade for bagging—this is strictly for mulching.
