04771200 Medium Lift Blades Kit Compatible with 52" Deck A-riens Ikon Gravely ZTX Zero Turn Lawn Mowers，Replace 00450300 70716200, 3 Pack

What It Is

This is a 3-pack of medium-lift replacement blades designed for 52-inch cutting decks on Ariens Ikon and Gravely ZTX zero-turn mowers. The medium lift profile balances bagging performance with clean side discharge, making it suitable for regular residential and light commercial mowing.

Fitment & Compatibility

Before buying, confirm your deck is exactly 52 inches (measured blade tip to blade tip). These blades replace OEM part numbers 00450300 and 70716200. Fit specific models: Ariens Ikon XD 52, Ikon XL 52, and Gravely ZTX 52. Also compatible with some ZT HD 52 models. Measure your existing blade length (should be 18 inches) and center hole diameter (must be 5/8 inch). Check that your spindle bolt pattern matches—these use a standard 5-point star center hole. Not for 48-inch or 60-inch decks, and not for non-Ariens/Gravely brands without cross-referencing.

Key Things to Know

• Quality vs OEM: Aftermarket blades at this price point may be slightly thinner steel than OEM. They work fine for normal grass but can dull faster on sandy soil or heavy weeds.
• Installation: Straightforward swap—remove one bolt per blade, but use a torque wrench to tighten to 70-90 ft-lbs. Always lift the deck and block it safely before getting underneath.
• Common gotcha: The medium lift design increases grass clumping in wet conditions. Bagging performance is decent, but not as aggressive as high-lift blades. For mulching, you’ll need a dedicated mulching blade set.
• Balance check: Aftermarket blades sometimes come unbalanced. Spin each blade on a nail or balancer before mounting—an unbalanced blade causes vibration and premature spindle wear.

Should You Buy It

If you own an Ariens Ikon or Gravely ZTX with a 52-inch deck and need a budget-friendly replacement for regular mowing (not heavy commercial use), this kit delivers solid value. It’s not for pros who mow daily or for wet/overgrown conditions—but for homeowners and light users, it’s a practical alternative to pricier OEM blades.
