8TEN LawnRAZOR Replacement Mower Blades for Ariens 04265400 — Notched High-Lift 3-Pack, 14" x 2" OEM Fit

These are 8TEN LawnRAZOR notched high-lift replacement mower blades — a 3-pack designed to fit Ariens/Gravely OEM 04265400 42" decks for cleaner, more consistent cuts.

If your Ariens or Gravely zero-turn mower with a 42" deck needs replacement blades, the 8TEN LawnRAZOR high-lift notched blades are engineered to match OEM fit and restore cutting performance. Each blade measures 14" long with a 5/8" center hole, 2" width and 0.197" thickness, and the notched high-lift profile helps with material flow across the deck for better bagging and clippings evacuation.

Will these blades fit my Ariens or Gravely 42" deck?

Yes — these LawnRAZOR blades are made to be compatible with the OEM part number and the specified models. They are sized to the same key dimensions and mounting hole so installation is straightforward for the listed machines.

• Direct OEM compatibility: Ariens/Gravely part number 04265400
• Fits Ariens 42" decks: models 915159, 915171 (Zoom series)
• Fits Gravely 42" decks: models 915148, 915170 (ZT 42)
• Blade dimensions: 14" length, 5/8" center hole, 2" width, 0.197" thickness

How do notched high-lift blades affect cutting and clippings?

The notched high-lift edge creates stronger upward airflow under the deck to pull grass into the blade’s cutting path and move clippings toward the discharge or bagging system. This improves cut consistency across varying grass heights and densities without changing deck geometry.

• High-lift design increases airflow for cleaner cuts
• Notches help prevent clumping and improve material flow
• Better bagging performance and more even discharge
• Maintains factory mounting and blade balance

What should I expect when swapping to these replacement blades?

When you replace worn or damaged blades with this 3-pack, expect improved cutting performance and a more uniform finish across your lawn. Installation is similar to OEM blades; always follow torque specs and balance each blade to prevent vibration.

• 3 blades in the pack let you service a full 3-blade 42" deck
• Use proper blade bolts and torque per your mower manual
• Check and balance blades before final installation
• Sharp edges and proper lift restore mower efficiency

How durable and precise are the LawnRAZOR blades?

8TEN LawnRAZOR blades are manufactured to maintain consistent thickness and hole alignment so they mount securely and hold balance. The steel gauge and profile are chosen to resist deformation while delivering a reliable cutting edge when maintained correctly.

• Consistent 0.197" thickness for strength and stability
• Accurate 5/8" center hole for OEM-style mounting
• Heat-treated or finished edges extend service life (follow care guidelines)
• Replace in matched sets to avoid uneven deck wear

Who is this for: The 8TEN LawnRAZOR 3-pack is aimed at homeowners, landscapers, and maintenance technicians who own Ariens or Gravely zero-turn mowers with a 42" deck and need OEM-compatible replacement blades. It’s especially useful for users who want to restore original cutting performance, improve bagging and discharge, and replace a full set of blades at once. Install with proper safety equipment, follow your mower’s service manual for torque and blade orientation, and rebalance blades after sharpening for best results.
