Super Recycler 21" Replacement Lawn Mower Blade Fits Toro 108-3762-03

What It Is

This is a genuine Toro OEM replacement blade designed for the Super Recycler 21" mower series. It uses the unique “Recycler” cutting action that recirculates clippings for finer mulching, ideal for lawns where bagging isn’t preferred.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 21" Toro decks – measure your deck width to confirm.
• Model series: Fits Toro Super Recycler models (e.g., 20370, 20371, 20373, 20378). Check your mower’s model number under the seat or on the deck.
• OEM part number: This is Toro part #108-3762-03. Do not substitute aftermarket blades – they often have different hole patterns or thickness that can cause vibration or poor cut.
• Blade dimensions: 21" length, 1.25" center hole, 0.25" thickness. Measure your old blade’s hole size and thickness to confirm match.
• Not for: Standard Recycler, Personal Pace, or any non-Super Recycler models. Verify your mower’s model number ends with “Super Recycler.”

Key Things to Know

• Quality: Genuine Toro blade with heat-treated steel and balanced design. Expect long life with normal use.
• Installation difficulty: Easy – requires a socket wrench and blade removal tool (or block of wood to prevent spinning). Torque to 50-60 ft-lbs.
• Common gotcha: The blade has a specific “up” side with a stamped arrow. Installing upside down ruins cut quality and can damage deck. Also, check your deck’s spindle for wear before installing – a wobbly spindle will wear the new blade fast.
• Price note: At $89.99, this is premium OEM pricing. Aftermarket alternatives exist for ~$25, but they often lack the exact air-lift profile and may reduce mulching performance.

Should You Buy It

If you own a Toro Super Recycler 21" mower and want to maintain its factory mulching performance, this blade is the correct choice. It’s overkill for standard Recycler models and too expensive for casual users who could swap to a cheaper aftermarket blade. But for owners who value that fine, even clippings and don’t want to bag, this OEM part delivers.
