What It Is

This is a genuine Toro mulching blade (OEM part 108-9764-03) designed to replace the blade on 22-inch Toro Recycler mowers. It uses a curved, high-lift design to recirculate clippings for fine mulching, ideal for homeowners who want to leave clippings on the lawn.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 22 inches across. This blade fits Toro Recycler models 20370, 20371, 20372, 20373, 20374, 20377, and 20378. It also replaces older OEM part 104-8697-03. The blade length is 21.625 inches (center hole to tip), with a 1-inch center hole and a 5-point star drive pattern. Measure your existing blade length and hole pattern—aftermarket blades with the same length but different center hole size will not work. This is a genuine Toro part, not an aftermarket substitute.

Key Things to Know

• Quality: OEM Toro steel construction, pre-balanced, and coated to resist rust. Expect consistent mulching performance.
• Installation: Requires a 15/16-inch socket or wrench. Use a blade removal tool or wedge a block of wood to prevent spinning. Torque to 35-40 ft-lbs.
• Gotcha: The star drive pattern is specific to Toro’s 22-inch Recycler decks—will not fit other brands or non-Recycler Toro models with a standard oval hole.
• Sharpening: Can be sharpened, but replacement is recommended every 2-3 seasons or after hitting rocks/roots.

Should You Buy It

Buy this if you own one of the listed Toro Recycler models and want a guaranteed OEM fit for reliable mulching. It’s a direct swap with no guesswork, justifying the higher price over aftermarket blades. Not suitable for bagging or side-discharge setups—use a standard blade for those.
