04771200 High Lift Lawn Mower Blades for 52" Deck, Compatible with A-riens IKON X XL XD,Edge, Gra-vely ZT X ZT XL Series Zero Turn Mower, 3 Pack

What It Is

This is a three-pack of high-lift lawn mower blades designed for 52-inch cutting decks, intended for use on zero-turn mowers from A-riens (IKON X, XL, XD, Edge) and Gra-vely (ZT X, ZT XL) series. The high-lift design increases airflow under the deck for better grass discharge and bagging performance, especially in tall or damp grass.

Fitment & Compatibility

• Deck size must be exactly 52 inches – these blades will not fit 48-inch, 54-inch, or 60-inch decks. Measure your deck width from spindle to spindle before ordering.
• Brand/model fit: Listed for A-riens IKON X/XL/XD/Edge and Gra-vely ZT X/ZT XL series. Use your mower’s model number (e.g., IKON-X 52, ZT X 52) to confirm.
• OEM vs aftermarket: These are aftermarket blades, not OEM A-riens or Gra-vely parts. They may differ slightly in thickness or balance. Check your OEM blade part number (e.g., 04771200) against the listing to verify compatibility.
• Measurements: Blade length should be approximately 20.5 inches, center hole diameter about 1 inch, and thickness around 0.2 inches. Measure your current blade to confirm; mismatched center holes can cause wobble or damage.
• Check your deck’s spindle orientation – high-lift blades may require a specific offset. Confirm the blade’s lift direction matches your deck’s design (usually stamped on the blade or in your manual).

Key Things to Know

• Installation difficulty: Moderate – needs a socket wrench, torque wrench (recommended 70-90 ft-lbs), and blade removal tool or block of wood to lock the spindle. Not for beginners without mechanical confidence.
• Balance: Aftermarket blades may arrive slightly unbalanced. Test balance by hanging the blade on a nail; if one side dips, grind the heavy side lightly. Unbalanced blades cause vibration and wear spindles faster.
• Durability: These are typically made from hardened steel, but quality can vary. Check for burrs or uneven edges on arrival – return if defective.
• Common gotcha: High-lift blades create more suction but also more drag, which may reduce engine RPM slightly on underpowered mowers. Ensure your mower has at least 20-24 HP for best results.

Should You Buy It

Buy these if you need a budget-friendly replacement for a 52-inch A-riens or Gra-vely zero-turn mower, primarily for bagging or fast discharge in thick grass. Avoid if you require OEM precision, need mulching blades, or have a mower under 20 HP – the high-lift design may strain smaller engines. For casual homeowners with moderate mowing, these offer solid value.
