What It Is

This is a set of mulching blades designed for Toro 22-inch mower decks, specifically the Grasscool Recycler and Atomic blade styles. They replace OEM part 108-9764-03 and are intended for superior grass clipping recirculation and fine mulching.

Fitment & Compatibility

• Deck size: Only fits 22-inch Toro mower decks (not 21" or 30").
• Model fit: Works with Toro Recycler, Super Recycler, and TimeCutter models that use a 22" deck (e.g., 20333, 20332, 20331, 21445, 21465, 20016, 20334, 59534p).
• OEM cross-reference: Replaces Toro 108-9764-03, 131-4547-03, and aftermarket numbers 59534p, 20333, 20016, 20331, 20332, 21445, 21465.
• Measure before buying: Check your current blade’s length (22" overall), center hole (5/8" hex), and thickness (~0.1875"). Also verify your spindle bolt pattern matches (these use a standard 5/8" hex center with two 1/4" offset holes).
• Not universal: Will not fit non-Toro brands or smaller/larger decks.

Key Things to Know

• Quality: 4.8 stars from 167 reviews; made from heat-treated steel with a coated finish to resist rust. Users report excellent mulching and less clumping than standard blades.
• Installation: Easy DIY—remove the center bolt, lift the old blade, and install new one with the cutting edge facing the direction of rotation (usually upward). Torque the bolt to 30–40 ft-lbs.
• Common gotchas: These are mulching blades (not bagging or side-discharge). They create finer clippings but may leave longer clippings if the grass is wet or too tall. Also, they fit some but not all Toro 22" decks—double-check your model number against the list.
• Pairing: For best results, use with a mulching plug/cover (sold separately if your mower didn’t come with one).

Should You Buy It

Yes—if you own a Toro 22" deck mower (Recycler or compatible model) and want premium mulching performance without paying OEM prices. It’s ideal for users who mow frequently and want fine clippings that decompose quickly. Avoid if you need bagging or side-discharge blades.
