Earthtec 133-8182-03 89914P 331387XB Mulching Blades Replacement Fits for Toro Super Recycler ，Exmark, LawnBoy 21 Inch Mower 109-0854 108-0954-03 116-4500 1164500S 1350413S (2 Pcs)

What It Is

This is a set of two mulching blades designed for Toro Super Recycler, Exmark, and LawnBoy 21-inch walk-behind mowers. They replace OEM part numbers 109-0854, 108-0954-03, 116-4500, 1164500S, and 1350413S, and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits 21-inch cutting decks only. Measure your deck width if unsure.
• Model/brand: Confirmed for Toro Super Recycler (e.g., 20333, 20338, 20340), Exmark Quest, Turf Tracer, and LawnBoy 10600/10700 series. Not for standard Toro Recycler or 22-inch decks.
• OEM cross-reference: Matches Toro 109-0854, 108-0954-03, 116-4500, 1164500S, and 1350413S. Check your current blade’s part number stamped on it.
• Center hole: 5/8-inch round hole with 1-inch offset. Measure your spindle’s bolt pattern to confirm.

Key Things to Know

• Quality: Aftermarket blades from Earthtec; generally well-reviewed for balance and sharpness, but may not hold an edge as long as OEM Toro blades (softer steel).
• Installation difficulty: Easy if you have a socket wrench and blade removal tool. Torque to 55–65 ft-lbs. Use thread locker if your mower vibrates heavily.
• Common gotcha: These are mulching blades—they have a curved, wing-like design. Do not use them for bagging or side-discharge unless your deck has a separate discharge plug.
• Check blade orientation: The curved side faces upward toward the deck; the flat side faces the grass. Installing upside down will cause poor cut and vibration.

Should You Buy It

If you own a compatible 21-inch Toro Super Recycler, Exmark, or LawnBoy mower and want an affordable mulching blade set for regular grass cutting, this is a solid choice. For heavy-duty or commercial use, consider OEM Toro blades for longer life, but for homeowners, these offer good value at $40.18 for two.
