What It Is

This is a Toro Genuine OEM mulching blade (part number 131-9683-03) designed specifically for 22-inch Toro Recycler mowers. It replaces the standard cutting blade to chop grass clippings into finer pieces that decompose quickly and can be left on the lawn as natural fertilizer.

Fitment & Compatibility

Before buying, confirm:

• Mower deck size: Only fits 22-inch Toro Recycler models (not 21-inch or 30-inch decks).
• Exact model numbers: Compatible with models 20956, 20958, 20959, 20960, 20961, 20964, 20965, 21761–21774, and 21863. Check your mower’s model number (usually under the seat or on the deck).
• OEM vs aftermarket: This is Toro’s genuine blade, so fitment is guaranteed for listed models. Aftermarket blades may differ in thickness, balance, or hole alignment.
• Measurements: Blade length = 22 inches, center hole diameter = 1 inch, offset = 0.5 inches. Verify these against your current blade if replacing a non-OEM part.

Do not assume it fits all Toro 22-inch mowers—only the Recycler series listed.

Key Things to Know

• Quality: OEM blade is heat-treated and balanced from the factory. Expect longer edge retention and less vibration than generic replacements.
• Installation difficulty: Easy—requires a socket wrench (typically 5/8-inch or 15/16-inch). Torque to 40-55 ft-lbs. Use a blade removal tool or block of wood to prevent rotation.
• Mulching only: This blade is not designed for bagging or side discharge. If you switch between collection methods, you’ll need a separate standard blade.
• Sharpening: Can be sharpened, but once bent or nicked, replace immediately. Running a dull mulching blade tears grass instead of cutting it.

Should You Buy It

Buy this if you own one of the listed Toro Recycler models and want the best mulching performance from your mower. It’s the right choice for homeowners who leave clippings on the lawn and want a clean, fine cut without clumping. If you bag or discharge, or have a different Toro model, look for the correct blade for your setup.
