8TEN LawnRAZOR Mower Blade for Snapper Simplicity 560Z 360Z Courier XT Contender 5104045YP 61-Inch Deck High Lift 3 Pack

What It Is

The 8TEN LawnRAZOR Mower Blade is a high-lift replacement blade designed for Snapper and Simplicity zero-turn mowers with a 61-inch deck. It’s built for heavy residential or commercial mowing, offering superior grass discharge and bagging performance.

Fitment & Compatibility

• Deck size: Fits 61-inch cutting decks only—verify your deck measures exactly 61 inches.
• Models: Compatible with Snapper 560Z, 360Z, Courier XT, and Contender; also fits Simplicity 560Z and 360Z.
• OEM reference: Replaces Snapper OEM part number 5104045YP.
• Measurements: Blade length is 20.5 inches, center hole diameter is 5/8 inch, and thickness is 0.203 inch. Measure your existing blade to confirm these specs.
• Quantity: Sold as a 3-pack—one per spindle on a 3-blade deck.
• Check: Ensure your deck uses high-lift blades (not standard or mulching) and that blade mounting bolts are compatible (typically 5/8-inch).

Key Things to Know

• High-lift design: Increases airflow for better bagging and side discharge, but may reduce lift on uneven terrain or thick wet grass.
• Installation: Moderate difficulty—requires removing the deck or accessing spindles with a socket wrench. Torque bolts to 70-90 ft-lbs (check your manual).
• Balance: Blades come pre-balanced, but always recheck balance after sharpening to avoid vibration.
• Durability: Heat-treated steel holds an edge longer than standard blades, but avoid hitting rocks or stumps to prevent bending.

Should You Buy It

Buy this if you own a Snapper or Simplicity 61-inch zero-turn and need reliable, high-lift blades for bagging or discharge mowing. It’s a cost-effective OEM replacement that performs well in tall or thick grass. Skip it if you mulch or have a different deck size.
