Ariens 3PK Genuine OEM Gravely 04771200 52" Zero Turn Lawn Mower Blades

What It Is

This is a set of three genuine OEM blades for Ariens and Gravely 52-inch zero-turn mowers. They are designed for residential and commercial cutting on medium-to-large lawns, providing a clean, mulching-capable cut.

Fitment & Compatibility

• Deck size: Must be exactly 52 inches. Measure your deck width before buying.
• Model fit: Fits Ariens Zoom and Gravely ZT/Pro series zero-turn mowers with a 52-inch deck. Common compatible models include Ariens Zoom 1542, 1642, 1842, and Gravely ZT 42, ZT 52, Pro-Turn 52 (check your model number).
• OEM vs aftermarket: This is genuine Ariens/Gravely OEM (part number 04771200). Aftermarket blades (e.g., Oregon, Stens) may fit but can differ in thickness, balance, or lift. OEM ensures perfect fit and warranty compliance.
• Measurements: Each blade is approximately 18 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset. Verify your existing blade’s length, width, and hole pattern before purchase.

Key Things to Know

• Quality: Made from heat-treated steel for durability. They hold an edge longer than many aftermarket blades but will still dull over time—replace every 25-50 hours or when cut quality drops.
• Installation: Moderate difficulty. You’ll need a socket wrench, jack or mower lift, and safety blocks. Torque the blade bolts to 70-90 ft-lbs. Always disconnect the spark plug and battery first.
• Common gotcha: The blades are sold as a set of three—do not mix with other blade lengths or brands on the same deck. Uneven blades cause vibration, poor cut, and spindle wear.
• Sharpening: These can be sharpened once or twice, but OEM blades are thin enough that over-sharpening reduces lift. Replace rather than sharpen more than twice.

Should You Buy It

Buy this set if you own a 52-inch Ariens or Gravely zero-turn and want a guaranteed fit, OEM quality, and long-lasting cut. It’s ideal for homeowners who mow weekly and prefer hassle-free replacement over aftermarket trial-and-error. Skip it if you have a different deck size or prefer cheaper aftermarket blades for occasional use.
