Hipa 131-4547-03 Mulching Blade Set for Toro 22 Inch Recycler Lawn Mower Lawn Tractor Model Parts Replace 108-9764-03 Blade Pack of 1

What It Is

This is a replacement mulching blade set (pack of 1) designed specifically for Toro 22-inch Recycler walk-behind mowers. It uses the OEM-style wing profile to cut and recirculate grass clippings into fine particles for nutrient return to the lawn.

Fitment & Compatibility

• Deck size: 22-inch (fits Toro Recycler models with 22" stamped steel deck only – not 21" or 24" decks).
• OEM reference: Replaces Toro part #108-9764-03 (also known as Hipa #131-4547-03). This is an aftermarket blade, not OEM Toro.
• Measurements: Center hole diameter is 7/8-inch; blade length is approximately 22 inches overall. Check your existing blade’s center hole and length before ordering.
• Model check: Confirmed fit for Toro Recycler models 20331, 20332, 20333, 20334, 20335, 20340, 20341, 20342, 20343, 20350, 20351, 20352, 20353, and 20370. Verify your model number on the mower’s serial tag.
• Quick check: If your current blade ends in -9764, this will swap in directly.

Key Things to Know

• Mulching only: This blade is designed for mulching, not bagging or side-discharge. It does not have a high-lift wing for bagging.
• Installation difficulty: Easy – requires a socket wrench, torque wrench (recommended 50-60 ft-lbs), and a block of wood to lock the blade. No special tools beyond that.
• Balance check: Aftermarket blades sometimes need balancing. Spin-test on a blade balancer or nail before installing to avoid vibration.
• Sharpness out of box: These come sharp but may benefit from a quick touch-up with a file before first use. Duller than OEM out of the package per some user reports.

Should You Buy It

Buy this if you own a Toro 22-inch Recycler, want a budget-friendly replacement for the OEM 108-9764-03 blade, and primarily mulch your grass. It works well for typical residential lawns but skip it if you need a bagging blade or want OEM fit/finish without balancing hassle.
