131-4547-03 Mulching Blades Replacement for to-ro 22" Recycler Mower Replacement Blade 131-4547-03 Mulching Mower Blade Replaces

What It Is

This is an aftermarket mulching blade set designed to replace the OEM 131-4547-03 blade on Toro 22" Recycler mowers. It cuts grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

• Deck size: Only fits 22-inch cutting decks. Do not use on 21" or 24" mowers.
• Model fit: Compatible with Toro Recycler models that originally use OEM part 131-4547-03. Common models include 20333, 20334, 20339, 20340, 20350, 20351, and 20352. Check your mower’s model number under the seat or on the deck.
• OEM vs aftermarket: This is a non-OEM replacement. It may have slightly different blade thickness or balance compared to the genuine Toro part. Measure your existing blade’s center hole diameter (should be ~1" with a star-shaped drive) and overall length (22") to confirm match.
• What to verify: Ensure your mower uses a single blade (not a dual-blade system) and that the blade adapter/carriage bolt pattern matches. Most Toro 22" Recyclers use a 5-point star center hole.

Key Things to Know

• Quality: With a 5.0 rating from a single review, reliability is unproven. Inspect for sharpness, balance, and warping before installation.
• Installation difficulty: Easy—requires a socket wrench and a block of wood to prevent blade rotation. Torque the center bolt to 35-45 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: Aftermarket blades may not be as durable as OEM. Check for cracking after heavy use or hitting rocks. Also, mulching blades work best with dry grass; wet clippings may clump.
• Lift vs. mulching: These blades have a curved design for lift and a serrated edge for cutting. They are not universal—do not use on standard discharge or bagging mowers expecting the same performance.

Should You Buy It

Buy this if you own a Toro 22" Recycler, need a budget-friendly mulching blade replacement, and are comfortable verifying fitment and inspecting aftermarket quality. Skip it if you want guaranteed OEM durability or if your mower uses a different blade pattern—stick with genuine Toro 131-4547-03 for peace of mind.
