Ariens 6PK Genuine OEM Gravely 04771200 52" Zero Turn Lawn Mower Blades

What It Is

This is a set of six genuine OEM Ariens/Gravely 52-inch zero-turn mower blades (part number 04771200) designed to replace worn blades on select Ariens and Gravely commercial and residential zero-turn mowers. They are intended for standard mulching or side-discharge cutting on 52-inch decks.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 52 inches. These blades fit specific Ariens and Gravely models, including the Ariens Zoom (e.g., 915000 series) and Gravely Pro-Turn ZT HD/ZX series with 52-inch fabricated decks. Check your owner’s manual or existing blade part number—OEM part 04771200 is the only guaranteed match. Aftermarket equivalents may differ in thickness, hole pattern, or lift angle, so stick with OEM if you want a drop-in fit. Measure blade length (approx. 18.5 inches), center hole diameter (typically 5/8 inch), and offset before installing.

Key Things to Buy

• Quality & durability – These are OEM blades made from hardened steel, offering longer edge life and better balance than most aftermarket options. They resist bending on light debris.
• Installation difficulty – Moderate. You’ll need a socket wrench and a blade removal tool or block of wood to lock the spindle. Torque to 70–90 ft-lbs (check your manual). No special skills required.
• Common gotchas – Always replace blades in sets of three per spindle (six total) to keep the deck balanced. Mixing old and new blades causes vibration and uneven cut. Also, note that these are not gator or high-lift blades—if you bag frequently, consider a dedicated bagging blade.
• Cost vs. aftermarket – At ~$14 per blade, these are mid-range. Aftermarket sets can be cheaper but often need balancing or have shorter life.

Should You Buy It

Buy this set if you own a 52-inch Ariens or Gravely zero-turn and want a guaranteed fit, consistent cut quality, and OEM durability. It’s the right choice for routine blade replacement on commercial or residential decks where reliability matters more than saving a few dollars. If you’re on a tight budget or run a high-debris property, consider aftermarket alternatives, but expect to spend extra time on balancing and fitment checks.
