8TEN LawnRAZOR Mower Blade Set for Ariens Gravely ZTXL 2554 Zoom 54 inch Decks 02961700 70763400 (High Lift)

What It Is

This is a set of three high-lift mower blades designed for 54-inch Ariens and Gravely ZTXL 2554 Zero-Turn mowers. The high-lift profile increases airflow for better grass discharge and bagging performance, making it ideal for thick or wet grass.

Fitment & Compatibility

Check your deck size – this set fits only 54-inch decks. It replaces OEM part numbers 02961700 and 70763400. Verify your mower model – confirmed for Ariens Zoom 54 and Gravely ZTXL 2554; other models with the same deck may also work but double-check. Measure blade length – should be 18.5 inches, center hole 5/8-inch, with a 1-inch offset. Aftermarket note – these are not OEM, but match dimensions and mounting pattern exactly. If your deck uses a different blade pattern (e.g., 3-in-1 or mulching), these high-lift blades will not work for mulching.

Key Things to Know

• High-lift vs standard – generates more suction, which improves bagging and side-discharge but may increase engine load slightly. Not ideal for mulching.
• Installation – straightforward bolt-on replacement. Use a torque wrench to 70-90 ft-lbs. Check blade orientation: cutting edge faces upward when installed.
• Durability – heat-treated steel holds an edge well; expect 20-30 hours of mowing before sharpening. Balance blades after sharpening to avoid vibration.
• Common gotcha – these blades are thicker than some OEM ones; ensure your deck’s blade bolts are long enough (usually fine, but check if you see loose threads).

Should You Buy It

If you own an Ariens Zoom 54 or Gravely ZTXL 2554 and need reliable, high-lift blades for bagging or side-discharge, this set delivers solid performance at a fair price. It’s a direct fit with no modifications required. Skip it if you primarily mulch or want OEM parts.
