04771200 High Lift Blades for Ariens IKON X, IKON XL Gravely ZT X & XL Series 52 Inch Deck Zero Turn Mower - Heavy Duty Blade Replaces 00450300 70716200-3 Pack

What It Is

This is a set of three high-lift mower blades designed to replace OEM parts on Ariens IKON X, IKON XL, and Gravely ZT X & XL series zero-turn mowers with a 52-inch cutting deck. The high-lift design increases airflow for superior grass clipping discharge and bagging performance, making it ideal for thick or damp grass.

Fitment & Compatibility

Before purchasing, verify your mower’s deck size is exactly 52 inches—these blades will not fit 48-inch or 60-inch decks. Compatible with Ariens IKON X (model year 2019+) and IKON XL (2020+) series, plus Gravely ZT X and ZT XL models with the 52-inch fabricated deck. They replace OEM part numbers 00450300 and 70716200, but measure your current blade length (typically 20.5 inches) and center hole diameter (usually 1 inch) to confirm. Aftermarket blades may have slight thickness or balance differences—compare with your OEM blade before installation.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and blade removal tool (or block of wood to prevent spinning). Torque blade bolts to 70-80 ft-lbs—overtightening can strip the spindle.
• Quality: Heavy-duty steel with a powder coating that resists rust, but high-lift blades wear faster than standard blades due to increased air resistance. Expect to sharpen or replace them every 25-30 hours of mowing.
• Common gotcha: High-lift blades create more deck lift, which can cause scalping on uneven terrain. Lower your deck height slightly to compensate. Also, they may not fit if your spindles have a different hole pattern—check for a 5-point star or oval center hole.
• Performance: Excellent for bagging and side discharge, but not ideal for mulching. If you primarily mulch, consider a dedicated mulching blade.

Should You Buy It

Buy these if you have a 52-inch Ariens or Gravely zero-turn and need aggressive lift for bagging or wet grass, want an affordable aftermarket replacement, and don’t mind more frequent blade maintenance. Skip them if you mow mostly flat, dry lawns with mulching—standard blades will last longer.
