Oregon 54 Inch Lawn Mower Blades, Mower Blades for 54" Deck, 18-5/8" Length, Direct Replacement for 742-05056, 942-05056, 742-05056A and Fits Craftsman 1427A3ZW099, 14B7A3ZW099 and More (3 Pack)

What It Is

These Oregon 54-inch lawn mower blades are a direct replacement set for 54" zero-turn and riding mower decks. They are designed for medium-to-heavy residential mowing and light commercial use, providing a clean cut on standard turf.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Your mower must have a 54-inch cutting deck.
• Blade length: Each blade is 18-5/8 inches long. Measure your current blade from tip to tip; if it matches, these will fit.
• OEM cross-reference: These replace 742-05056, 942-05056, and 742-05056A. They fit Craftsman models 1427A3ZW099 and 14B7A3ZW099, plus many other Craftsman, Husqvarna, and Poulan Pro 54" decks. Check your owner’s manual or look up your model number on Oregon’s fitment chart if you’re unsure.

Key check: The center hole is 15/16" and the blade offset is 0.250". If your current blade has a different center hole or offset, these will not work.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. These blades are made from heat-treated steel and include a hardened cutting edge, but they are not as thick as OEM heavy-duty blades.
• Installation: Easy swap if you have a socket set and a torque wrench. Use anti-seize on the blade bolt to prevent rust seizing. Tighten to 70–90 ft-lbs.
• Common gotcha: The blades come in a 3-pack, but some 54" decks use 3 blades, others use 2. Verify your deck uses 3 blades before ordering.
• Sharpness out of box: They are sharp but not razor-edged. Expect to sharpen after 8–10 hours of use for best performance.

Should You Buy It

If you own a 54" deck that accepts 18-5/8" blades with a 15/16" center hole and you want a reliable, budget-friendly replacement set, these are a solid choice. They won’t match OEM durability for heavy commercial use, but for residential mowing, they offer good value and easy installation.
