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

What It Is

This is a pack of three genuine OEM replacement blades for Ariens and Gravely 52-inch zero-turn mowers, designed for medium to heavy residential or commercial cutting. They replace part number 04771200 and are intended for standard grass cutting, not mulching or bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 52-inch cutting deck and uses three blades. These fit most Ariens and Gravely ZT models (e.g., Zoom, Ikon, and Gravely Pro-Turn series) that require OEM part 04771200. Check your owner’s manual or existing blade part number—aftermarket blades may differ in thickness or hole pattern. Measure blade length: these are 18 inches long with a 1-inch center hole and 7-gauge thickness. They do not fit 48-inch or 60-inch decks, nor non-Ariens/Gravely brands without cross-reference verification.

Key Things to Know

• Quality: OEM blades are heat-treated and balanced for longer life and cleaner cuts than most aftermarket options. Expect 25–50 hours of use on normal turf.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Always disconnect the spark plug and block the deck before replacing. Torque bolts to 70–90 ft-lbs.
• Gotchas: These are high-lift blades, which can throw clippings farther; avoid using in dusty or sandy conditions to reduce wear. Check blade orientation (cutting edge faces forward) and replace all three at once for balanced cutting.
• Sharpening: Can be sharpened once or twice, but OEM blades are thin enough that repeated sharpening reduces lift. Replace if bent or nicked.

Should You Buy It

If you own a 52-inch Ariens or Gravely ZTR and want reliable, factory-spec performance without guesswork, this pack is a solid investment. It’s ideal for homeowners who cut weekly or light commercial users who prioritize cut quality and durability over saving a few dollars on aftermarket blades.
