108-3762-03 Lawn Mower Blade Replaces for Toro 133-8183-03 Blade Fits for 21 in Super Recycler Mower 22275 22275T 22282 22282T 21566 21566T 21568 21568T (2 PCS) (2, Black)

What It Is

This is a pair of aftermarket 21-inch replacement blades designed for Toro Super Recycler mowers. They are intended for cutting and mulching grass on residential lawns, matching the OEM 133-8183-03 blade profile.

Fitment & Compatibility

Before buying, verify your mower deck is exactly 21 inches and that your model number is on the compatibility list: 22275, 22275T, 22282, 22282T, 21566, 21566T, 21568, or 21568T. These are aftermarket blades, not genuine Toro parts, so confirm the mounting hole pattern (center hole and offset) matches your existing blade. Measure your current blade length, width, and thickness—these should be identical to the 108-3762-03 spec. If your mower uses a different blade (e.g., for GTS or Personal Pace models), these will not fit.

Key Things to Know

• Quality concerns: With only a 3.2 rating from 2 reviews, check for balance issues or thin metal before installing. Consider balancing the blades on a balancer or nail.
• Installation difficulty: Easy—use a socket wrench and block the blade to prevent spinning. Torque to 40-50 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: These are sold as a pair, but many Super Recycler models only use one blade. You’ll have a spare, but ensure you’re not overpaying for two if you only need one.
• Warranty risk: Using non-OEM blades may void your mower’s warranty if still active. Keep OEM blades for warranty service.

Should You Buy It

Buy these only if you have a listed Toro Super Recycler model, need a budget-friendly pair of blades, and are comfortable verifying balance and fitment yourself. If you prioritize reliability, warranty protection, or have a non-listed model, stick with genuine Toro 133-8183-03 blades.
