UDC Parts 04771200 Mower Blades Replacement for Ariens Ikon XD 52 Gravely ZTX ZT HD ZTXL52 Edge Ikon-X XL Onyx 70716200 915256 915267 915222 915223 915332 Zero-Turn Mowers/High Lift 3 Pack

What It Is

This is a set of three high-lift replacement blades designed for 52-inch zero-turn mowers, optimized for bagging and side-discharge on Ariens and Gravely commercial/residential models. The high-lift profile creates more airflow to lift grass for a cleaner cut and better clippings collection.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch deck—this set fits only that width. Compatible models include Ariens Ikon XD 52, Gravely ZTX, ZT HD, ZTXL52, Edge, Ikon-X, XL, and Onyx. OEM cross-references are 70716200, 915256, 915267, 915222, 915223, and 915332. Measure your current blade length (should be ~18 inches) and center hole diameter (typically 5/8 inch or 7/8 inch—check your spindle). These are aftermarket replacements; verify your spindle bolt pattern matches the blade’s offset and hole size. Not for 54-inch or other deck sizes.

Key Things to Know

• High lift vs. standard: These are louder and require more engine power than low-lift blades. If you mulch frequently, consider a dedicated mulching blade instead.
• Installation: Requires a torque wrench (50–70 ft-lbs typical) and a blade removal tool. Reverse thread on some models—check your manual.
• Durability: UDC blades are heat-treated steel but may dull faster than OEM Ariens/Gravely blades under heavy use. Sharpen every 10–15 hours for best performance.
• Balance: New blades are pre-balanced, but always check after sharpening. An unbalanced blade causes vibration and spindle wear.

Should You Buy It

If you need a budget-friendly three-pack for a 52-inch Ariens or Gravely zero-turn and primarily bag or side-discharge, this is a solid value. It’s not the best choice for mulching or if you want OEM-level longevity, but for the price, it’s a reliable replacement that performs well for most homeowners and light commercial use.
