131-4547-03 Mulching Blades for 22" Toro Recycler, 108-9764-03 Lawn Mower Blades Compatible with 20001 20003 20005 20007 20008 20009, Replaces 104-8697-03P 108-9764-02P 104-8697-03, 2 Pack

What It Is

This is a 2-pack of mulching blades designed for 22-inch Toro Recycler walk-behind mowers. They chop grass clippings into fine particles to return nutrients to the lawn, replacing OEM part numbers 104-8697-03P and 108-9764-02P.

Fitment & Compatibility

Before buying, check three things:

1. Deck size: These blades are specifically for 22-inch cutting decks. Measure your mower deck width—if it’s not 22 inches, these won’t fit.
2. Model numbers: Fits Toro Recycler models 20001, 20003, 20005, 20007, 20008, and 20009. Check your mower’s model plate (usually under the rear discharge door or on the frame).
3. OEM vs aftermarket: These are Toro-branded replacements, not generic. They match OEM specs for center hole diameter (about 1 inch), blade length (22 inches), and offset. If you have a different Toro Recycler model (e.g., 20353 or 20354), measure your existing blade length and hole pattern first—many 22-inch Recyclers share this blade, but verify.

Practical check: Remove one existing blade, lay it on top of the new one. They should match in length, hole placement, and curvature. If the old blade is worn, the new one will still align with the spindle holes.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench (usually 15/16” or 13/16” depending on your mower) and a block of wood to jam the blade. Torque to 50-60 ft-lbs. No special tools required.
• Mulching performance: These have a higher lift and curved design to recirculate clippings. They won’t bag or side-discharge well—use only for mulching. If you switch between modes, you’ll need a separate blade set.
• Common gotcha: The blade bolt is reverse-threaded on some Toro models (lefty-tighty, righty-loosey). Check your owner’s manual before wrenching to avoid stripping.
• Durability: Heat-treated steel, but they’ll dull faster than standard blades if you hit rocks or roots. Sharpen after 10-15 hours of use or when you see torn grass tips.

Should You Buy It

Buy this if you own a 22-inch Toro Recycler (models 20001–20009) and want OEM-quality mulching blades that drop in without modification. It’s a good value for a 2-pack at this price, especially if you mow frequently and need a spare. Skip it if you have a different deck size or prefer bagging/side-discharge—these are mulching-only.
