Earthtec 133-8182-03 89914P Mulching Blade Replacement Fits for Toro Super Recycler ，Exmark, LawnBoy 21 Inch Mower 109-0854 108-0954-03 （2Pack） (1PCS)

What It Is

This is a two-pack of aftermarket mulching blades designed to replace OEM blades on Toro Super Recycler, Exmark, and LawnBoy 21-inch mowers. They cut grass into fine clippings for nutrient recycling, reducing bagging need.

Fitment & Compatibility

Must check before buying:

• Deck size: Only fits 21-inch mowers (not 22" or larger).
• OEM cross-references: Replaces Toro 109-0854, 108-0954-03, and Exmark 103-3880. Confirm your mower model uses these numbers.
• Measurements: Blade length is 21 inches, center hole 7/8" diameter, offset 0.25". Measure your current blade to verify.
• Brand compatibility: Direct fit for Toro Super Recycler (models like 20333, 20339), Exmark 21" (Quest, Turf Tracer), and LawnBoy 21" (with 109-0854 blade). Not for non-Recycler Toro decks or older 20" mowers.
• Aftermarket note: Earthtec is not OEM; slight thickness or balance variation possible. Check blade thickness matches your spindle.

Key Things to Know

• Quality: 4.4 stars from 13 reviews; users report good mulching performance but note blades may be slightly thinner than OEM (0.156" vs 0.187"). Expect faster wear on rocky lawns.
• Installation: Easy—remove old blade, clean spindle, install with washers in correct order (washer against blade, then lock washer). Torque to 50-60 ft-lbs. Use a blade puller if stuck.
• Gotcha: Mulching blades have a higher lift; they can cause excess vibration if not balanced. Test spin after install and balance with a blade balancer if needed.
• Pack size: Two blades per pack; good for dual-blade decks or spares, but single-blade owners will have an extra.

Should You Buy It

Buy if you need a budget-friendly replacement for a Toro Super Recycler, Exmark, or LawnBoy 21" mower and prioritize mulching over bagging. Avoid if you want OEM durability or have a rocky/muddy lawn where thinner blades may chip faster.
