04771200 Lawn Mower Blades (3 Pack) - High Lift Replacement for Ariens IKON X XL XD Edge & Gravely ZT X XL 52 Inch Zero Turn Mowers - Replaces 00450300 70716200

What It Is

This is a 3-pack of high-lift replacement blades designed for 52-inch zero-turn mowers, specifically Ariens IKON X/XL/XD/Edge and Gravely ZT X/XL models. The high-lift profile increases airflow for superior grass clipping discharge and bagging performance in thick or wet grass.

Fitment & Compatibility

• Deck size: 52-inch cutting decks only. Measure your deck width before ordering—these will not fit 48”, 54”, or 60” decks.
• Models: Ariens IKON X, XL, XD, Edge; Gravely ZT X, XL, ZT HD (52” decks). Check your model number on the deck or owner’s manual.
• OEM replacements: Replaces Ariens/Gravely part numbers 00450300 and 70716200. If your current blades have different OEM numbers, verify center hole size (commonly 7/8” or 1”) and blade length (typically 17.75” on these decks).
• Measurements: Each blade is ~17.75” long, 2.5” wide, with a 7/8” center hole. Confirm these match your existing blade.

Key Things to Know

• High-lift vs standard: High-lift blades create more suction—great for bagging and discharging, but they increase engine load and can leave scalped streaks on dry, thin grass. Not ideal for mulching.
• Installation: Straightforward with a socket wrench and torque wrench (aim for 40-50 ft-lbs). Use thread locker on spindle bolts to prevent loosening. Always sharpen new blades before first use.
• Balance check: After sharpening, balance each blade on a balancer or nail. An unbalanced blade causes vibration, spindle wear, and poor cut quality.
• Warranty note: Aftermarket blades may void OEM warranty on spindles or deck. Check your mower’s warranty terms before swapping.

Should You Buy It

Buy if you have a 52” Ariens IKON or Gravely ZT series and want aggressive discharge/bagging performance at a lower cost than OEM. Avoid if you primarily mulch or mow fine lawns—standard or mulching blades will give a cleaner finish. The single review suggests satisfaction, but the lack of volume means you’re relying on spec fitment.
