02961700 High Lift Mower Blades for Ariens Gravely 54 Inch Deck Zoom ZTXL 2554 ZTXL 2448 ZTXL 2548 ZTXL 48 ZT XL 48 Zoom XL 54 Zoom XL 42 54" Zero Turn Mowers Replace 70763400 Blades 3 Pack

What It Is

This is a set of three high-lift mower blades designed for 54-inch Ariens and Gravely Zero Turn mowers, including the Zoom ZTXL and Zoom XL series. High-lift blades create stronger airflow to improve grass clipping discharge and bagging performance, making them ideal for tall or wet grass conditions.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: This 3-pack fits only 54-inch cutting decks. It will not work on 42-inch, 48-inch, or 60-inch decks.
• Model compatibility: Fits Ariens Gravely Zoom ZTXL 2554, ZTXL 2448, ZTXL 2548, ZTXL 48, ZT XL 48, Zoom XL 54, Zoom XL 42, and Zoom 54 zero-turn mowers. Also replaces OEM part 70763400.
• Measurements: Blade length is approximately 18 inches (center hole to tip). Center hole is 5/8 inch diameter with a 7-point star drive pattern. Check your existing blade shape—these are high-lift, not standard or mulching blades.

Double-check your deck model number (found on the deck or frame tag) to avoid returning the set.

Key Things to Know

• Performance trade-off: High-lift blades improve bagging and discharge but create more dust and wear faster in sandy or dry conditions. Not ideal for mulching.
• Installation: Easy DIY job—remove the blade bolt (typically 9/16" or 5/8" socket), replace blade with the lift edge facing up toward the deck, and torque to 70–90 ft-lbs. Use thread locker.
• Balance check: Aftermarket blades may need balancing before install. Use a blade balancer tool—unbalanced blades cause vibration and deck damage.
• Star drive fitment: The 7-point star center hole must match your spindle. Some older decks use a round hole with a keyway—verify before buying.

Should You Buy It

Buy this set if you own a compatible 54-inch Ariens/Gravely zero-turn and need better bagging or discharge performance in thick grass. Skip it if you primarily mulch or mow in dry, dusty conditions—standard or mulching blades will serve you better with less dust and longer life.
