What It Is

This is a genuine Toro OEM 2-pack of replacement blades (model 133-8183-03) designed specifically for 21" Toro Super Recycler lawn mowers. They provide the cutting and mulching action required for that deck.

Fitment & Compatibility

• Deck size: 21 inches only. Do not use on any other deck width.
• Model compatibility: Fits Toro Super Recycler models that originally used blades 108-3762-03, 22275, 22275T, 22282, 22282T, 21566, 21566T, 21568, or 21568T.
• OEM vs aftermarket: These are genuine Toro parts. Aftermarket blades may have different hole patterns or thickness, causing poor balance or fit.
• Measurements: Blade length is 21", center hole diameter is 1", and the blade is 0.19" thick. Verify these against your current blade before buying.
• How to check: Look for the model number on your mower’s serial tag (under the rear flap or near the engine). Cross-reference it with the compatible blade numbers listed above.

Key Things to Know

• Quality: Toro OEM blades are heat-treated and balanced for long life and consistent cut. Aftermarket blades often dull faster or vibrate.
• Installation difficulty: Easy – one bolt per blade (5/8" socket). Torque to 35-40 ft-lbs. No special tools needed.
• Common gotcha: The blade’s “sail” (bent-up section) must face upward toward the deck. Installing upside down will ruin cut quality and can damage the mower.
• Mulching vs bagging: These are “Recycler” blades designed for mulching. If you bag frequently, consider Toro’s bagging blade (model 108-3762-03) instead.

Should You Buy It

Buy this if you own a 21" Toro Super Recycler and want a guaranteed fit, reliable performance, and OEM durability. It’s ideal for homeowners who mow weekly and want consistent mulching without vibration or premature wear. Skip it if you have a different brand, a non-Super Recycler Toro, or if you primarily bag clippings.
