Fits Toro Walk Behind Mower Blade Fits Super Recycler 21" Replaces 108-3762-03

What It Is

This is a genuine Toro 21-inch mulching blade designed specifically for Super Recycler walk-behind mowers. It replaces OEM part number 108-3762-03 and is optimized for fine clipping shredding and bagging performance on residential lawns.

Fitment & Compatibility

• Deck size: Only fits 21-inch Toro Super Recycler decks. Measure your blade length—this blade is exactly 21 inches from tip to tip.
• Model check: Confirmed fit for Super Recycler models (e.g., 20353, 20354, 20355, 20370, 20371). Not compatible with standard Recycler or Personal Pace models without Super Recycler branding.
• OEM vs aftermarket: This is a genuine Toro blade, not an aftermarket copy. It matches factory specs exactly—no modification needed.
• Center hole & offset: Uses a standard 1-inch center hole with a 5-point star drive. Blade offset is 0.75 inches. Verify your spindle matches before buying.
• Check your old blade: Remove one bolt and compare the part number stamped on your existing blade. If it reads 108-3762, 108-3762-01, or 108-3762-02, this replacement is correct.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench, torque wrench (recommended 70–90 ft-lbs), and a blade removal tool. No special skills needed.
• Mulching performance: The curved wing design lifts clippings for recutting. Expect finer discharge than standard lift blades, but it may clog in wet grass.
• Sharpness out of box: Comes sharp but not razor-edge. A quick touch-up with a file before first use improves cut quality.
• Balance check: Always balance after sharpening. Even new blades can be slightly off—use a blade balancer to avoid vibration and spindle wear.
• Torx bolts: Uses 5-point Torx bolts (T-27 or T-30 depending on model). Have the correct bit ready; stripping these is common.

Should You Buy It

If you own a Toro Super Recycler 21” and want a factory-perfect replacement that maintains mulching performance and eliminates guesswork, this blade is the right choice. It’s priced slightly higher than generic options but avoids fitment headaches and delivers consistent results. Skip it if you have a standard Recycler or a different deck size—it won’t fit.
