What It Is

This is a 2-pack of mulching blades designed for Toro 22-inch Recycler walk-behind mowers. They cut grass into fine clippings that decompose quickly, eliminating the need for bagging in most conditions.

Fitment & Compatibility

Before buying, verify your mower’s model number matches one of these: 20017, 20334, 20339, 20331, 20370, 20378, 21465, or 20005. These blades replace OEM part numbers 108-9764-03, 108-9764, 108-9764-02P, 104-8697-03, and 131-4546-03. They fit exclusively on 22-inch deck Toro Recyclers—not on 21-inch or other deck sizes. Measure your existing blade length (should be ~22 inches center-to-center) and check the center hole diameter (typically 7/8-inch) before ordering. These are aftermarket blades, not genuine Toro, but match OEM specs.

Key Things to Know

• Quality: Made of hardened steel, but some users report they dull faster than OEM blades. Inspect after heavy use.
• Installation: Easy swap with a socket wrench—just remove the blade bolt, replace, and torque to 30-40 ft-lbs. Use thread locker if your mower vibrates.
• Common gotcha: These blades are for mulching only. Do not use with a bagging attachment or side discharge—they won’t work well.
• Pack size: You get two blades, so rotate them when one dulls, extending time between replacements.

Should You Buy It

If you own a 22-inch Toro Recycler and want a budget-friendly mulching blade set for frequent cutting, this is a solid choice. It’s not the longest-lasting option, but at $29.99 for two, it’s good value for light-to-moderate use. For heavy-duty or commercial mowing, stick with genuine Toro blades.
