108-3762-03 Super Recycler Mower Blade (21") Fits Toro 20090 20095 20794

What It Is

The 108-3762-03 is an OEM Toro 21-inch Super Recycler mower blade designed for Toro’s Super Recycler walk-behind mowers. It’s optimized for mulching grass clippings finely and recirculating them into the lawn, reducing bagging frequency.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches (measure the blade mounting hole to hole or the deck’s cutting width). This blade is OEM Toro, not aftermarket, so it’s a direct fit for Toro models 20090, 20095, and 20794. Double-check your mower’s model number (usually on a sticker under the seat or on the deck). The blade uses a center hole with a 5/8-inch diameter and a 1-inch star-shaped drive hole—verify your spindle matches. It is not compatible with Toro’s standard 21-inch blades (e.g., 108-3762-01) or other brands’ decks.

Key Things to Know

• Quality: OEM Toro steel blade, balanced from the factory. Sharp out of the box; no need to sharpen immediately.
• Installation: Requires a 5/8-inch socket or wrench for the center bolt. Torque to 70-80 ft-lbs (check your manual). Use a blade-stopper tool to prevent spinning.
• Common Gotcha: This blade is directional—the “Super Recycler” wings must face upward toward the deck. Installing upside down will cause poor mulching and vibration.
• Lifespan: Replace every season or after 25 hours of use, or sooner if you hit rocks or roots. Dull blades tear grass, leading to browning.

Should You Buy It

If you own a Toro Super Recycler (models 20090, 20095, 20794) and want the factory-specified mulching performance, this is the correct blade. It’s a no-brainer for owners who prioritize fine clippings and less bagging. If you have a different Toro model or a non-Toro mower, skip it—fitment is narrow.
