What It Is

This is a 21-inch replacement blade for Toro Super Recycler mowers, designed to lift and cut grass while recirculating clippings for finer mulching. It fits select Toro models (22275, 22275T, 22282, 22282T, 21566, 21566T, 21568, 21568T) and replaces OEM part numbers 93-4106 and 93-4106-03.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches (not 22 inches or other sizes). Check your model number on the mower’s serial tag (under the rear flap or near the engine). This blade is aftermarket, not OEM Toro, so verify the blade length (21 inches), center hole diameter (typically 1 inch), and drive pin pattern. Measure your old blade’s thickness and air lift profile to match. It does not fit standard Toro Recycler or other 21-inch models outside the Super Recycler line.

Key Things to Know

• Quality: Aftermarket blade; may not match OEM steel hardness or balance. Inspect for warping or uneven edges before installation.
• Installation: Easy with a socket wrench. Use a blade removal tool or block the blade to prevent spinning. Torque to 40–50 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: The blade’s lift angle and wing design may differ slightly from OEM, affecting bagging or mulching performance. Test on a small patch before full use.
• Sharpening: Can be sharpened, but aftermarket blades often wear faster. Replace if bent or chipped.

Should You Buy It

If you own one of the listed Toro Super Recycler models and need a budget-friendly replacement for a worn or damaged blade, this is a decent option. But if you prioritize maximum mulching quality, long blade life, or perfect OEM fit, spend more on the genuine Toro blade (93-4106).
