What It Is

This is a 2-pack of mulching blades designed for 22-inch Toro Recycler lawn mowers. They replace OEM part numbers 59534P, 108-9764-03, and 104-8697-03, and are intended for machines that cut and recirculate grass clippings into fine particles for natural lawn feeding.

Fitment & Compatibility

Before buying, check these three things:

• Deck Size: Only fits 22-inch cutting decks. Measure your mower deck width to confirm.
• Model List: Compatible with Toro models 20377, 20333, 20016, 20331, 20332, 21445, and 21465. Verify your model number on the mower’s data plate (under the seat or near the engine).
• OEM vs Aftermarket: These are aftermarket replacements for OEM Toro blades. They should match the original hole pattern and blade length, but measure your old blade’s center hole diameter (typically 1-inch) and overall length (22 inches) to be certain.

Key Things to Know

• Quality: 4.5/5 rating from 18 reviews suggests good durability for residential use, but may not hold an edge as long as OEM Toro blades under heavy use.
• Installation: Easy bolt-on job. You’ll need a socket wrench and a block of wood to jam the blade. Torque bolts to 30-40 ft-lbs. Always disconnect the spark plug first.
• Common Gotcha: These are mulching blades only—they won’t bag or side-discharge well. If you switch between modes, consider a 3-in-1 blade instead.
• Check for Bent Spindles: If your old blade was damaged, inspect the spindle shaft for bends before installing the new blade.

Should You Buy It

If you own a Toro 22-inch Recycler mower and only use the mulching function, this 2-pack is a solid value at $29.99. It’s a direct fit for the listed models, easy to install, and gets good reviews. For heavy commercial use or if you need bagging/side-discharge capability, look for OEM 3-in-1 blades instead.
