Oregon 54 Inch Lawn Mower Blades, Mower Blades for 54" Deck, 18-3/4" Length, Replacement for Bad Boy OEM 038-0005-00 and Fits Bad Boy, MZ, CZT, ZT Avenger, Outlaw, Maverick, Revolt and More (3 Pack)

What It Is

This is a set of three Oregon replacement blades designed for 54-inch mower decks. They are intended for zero-turn mowers, specifically Bad Boy models like the MZ, CZT, ZT Avenger, Outlaw, Maverick, and Revolt, as well as other brands with compatible spindle patterns.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This set is for a 54-inch deck only. Measure your deck width—if it’s not 54 inches, these won’t fit.
• Blade length: Each blade is 18-3/4 inches long. Measure your current blade from tip to tip (center hole to tip). If it’s not exactly 18-3/4", these won’t match.
• OEM part number: These replace Bad Boy OEM part 038-0005-00. Check your owner’s manual or existing blade for this number. They also fit many Bad Boy zero-turn models, but always confirm the OEM number—don’t rely on brand name alone.
• Center hole and spindle pattern: These have a standard 5-point star center hole (common on Bad Boy and many zero-turns). If your spindles use a different pattern (e.g., round hole with keyway), they won’t fit.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. These are made from heat-treated steel and should match OEM durability for residential use. Not intended for commercial heavy-duty mowing.
• Installation difficulty: Easy—just a socket wrench, torque wrench (recommended 70-90 ft-lbs), and a blade removal tool. Watch for sharp edges.
• Common gotcha: The “54 inch” refers to the deck, not the blade length. If your deck is 54" but your blades are a different length (e.g., 18-1/2" or 19"), these won’t fit.
• Balance check: After installation, spin the blades by hand to ensure they’re balanced. Unbalanced blades cause vibration and damage spindles.

Should You Buy It

Buy these if you have a 54" Bad Boy zero-turn (or compatible brand) and your current blades are 18-3/4" long with a 5-point star center hole. They’re a solid, budget-friendly alternative to OEM blades for residential mowing. But if you mow commercially or need exact OEM fitment, stick with Bad Boy branded parts.
