SCITOO 3 Pack Lawn Mower Blade, 52 inches Blades Compatible for Ariens: 00273100, 00450300, 03253800, 03399704, 04916400, 04917900; for Bad Boy: 038-3000-00; for Ferris: 1521227

What It Is

This is a 3-pack of aftermarket 52-inch lawn mower blades designed to replace OEM blades on select zero-turn mowers from Ariens, Bad Boy, and Ferris. They are intended for medium-to-large residential or commercial mowing where a wide cutting deck is used.

Fitment & Compatibility

Before buying, confirm your mower’s deck size must be exactly 52 inches. The blades are listed as compatible with Ariens models using part numbers 00273100, 00450300, 03253800, 03399704, 04916400, 04917900; Bad Boy part 038-3000-00; and Ferris part 1521227. Measure your existing blade’s length, width, center hole diameter (usually 1 inch), and offset to ensure a match. These are aftermarket, not OEM—so verify that the mounting pattern and blade shape (e.g., high-lift, mulching) match your original. Check your mower’s model number against the list; if it’s not explicitly listed, do not assume fitment.

Key Things to Know

• Quality concerns: With only 6 reviews and a 4.4 rating, consistency is unproven. Some users report blades are thinner or less balanced than OEM—expect to sharpen and balance them before first use.
• Installation: Straightforward if you have a socket set and torque wrench. Always lift the mower deck, disconnect the spark plug, and use a block of wood to lock the blade. Torque to manufacturer spec (typically 70–90 ft-lbs).
• Common gotcha: The “52 inches” refers to deck width, not blade length. Each blade is roughly 18–20 inches long depending on deck design. Measure your old blade’s exact length before buying.
• Pack contents: You get three blades—enough for a triple-blade deck. Verify your mower uses three blades (most 52-inch zero-turns do).

Should You Buy It

This is a budget-friendly option if you have a compatible Ariens, Bad Boy, or Ferris 52-inch mower and are comfortable doing minor prep work like sharpening and balancing. It’s not ideal for those who want guaranteed OEM quality or who need blades that work out of the box without adjustment.
