Hipa 2 Pack 131-4547-03 Mulching Blades Set for Toro 22 Inch Recycler Lawn Mower Lawn Tractor Model Parts Replace 108-9764-03 Mower Blade

What It Is

This is a 2-pack of mulching blades designed for Toro 22-inch Recycler and select lawn tractor models. They replace OEM part numbers 131-4547-03 and 108-9764-03, and are intended for cutting grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 22-inch cutting deck. These blades fit Toro Recycler models (e.g., 20332, 20333, 20334) and select Toro lawn tractors with 22-inch decks. Check your current blade’s part number—if it’s 131-4547-03 or 108-9764-03, these are direct replacements. Measure your blade length (22 inches end to end), center hole diameter (typically 1-inch), and spindle hole pattern (usually 5-point star or oval). Verify your mower’s model number on the deck or under the seat; incompatible decks may cause poor cutting or vibration.

Key Things to Know

• Quality: These are aftermarket, not OEM Toro. They match OEM specs but may have slightly thinner steel (check thickness if you hit hard objects often).
• Installation: Easy with a socket wrench and blade removal tool. Torque to 50-60 ft-lbs (check your manual). Use thread locker if bolts are loose.
• Gotcha: Mulching blades have a curved, high-lift design—they won’t discharge clippings well for bagging or side-discharge. For optimal mulching, mow dry grass and keep blades sharp.
• Balance: These come pre-balanced, but after installation, spin the blade manually to confirm no wobble. Unbalanced blades cause vibration and deck damage.

Should You Buy It

If you own a Toro 22-inch Recycler or compatible tractor and want affordable mulching blades for fine clippings, this 2-pack is a solid value. It’s not for side-discharge or bagging use, and aftermarket quality means you’ll need to inspect for consistent thickness. Best for budget-conscious owners who mulch regularly and sharpen blades seasonally.
