Pro Parts Place, PPP 3 Genuine Bad BOY Blades 72" Decks Bad Boy 038-5400-00 Gator Mulching Blades 038-7230-00

What It Is

This is a set of three genuine Bad Boy branded Gator mulching blades designed for 72-inch Bad Boy mower decks. They replace OEM part numbers 038-5400-00 and 038-7230-00, optimized for fine-clipping mulching rather than side discharge or bagging.

Fitment & Compatibility

Before buying, verify your deck is exactly 72 inches (not 60 or 48). These fit Bad Boy models using the 038-5400-00 or 038-7230-00 blade pattern—commonly found on Bad Boy Outlaw, Maverick, and ZT series with 72-inch decks. Measure your existing blade length (center hole to tip) and ensure it matches the 20.5-inch length typical of these OEM blades. Check the center hole diameter (should be 5/8-inch) and the number of mounting holes (usually two). These are direct OEM replacements, not universal aftermarket, so cross-reference your mower’s serial number with Bad Boy’s parts diagram to confirm.

Key Things to Know

• Quality: Genuine Bad Boy Gator blades are heat-treated steel with a wave-edge design for aggressive mulching. They hold an edge well but dull faster on sandy or rocky lawns.
• Installation: Easy swap with a socket and torque wrench—tighten to 70-90 ft-lbs. Use a blade removal tool or block wood to prevent spinning. Always disconnect the spark plug first.
• Gotcha: These are mulching blades only. They will not bag or discharge effectively. If you need versatility, consider Bad Boy’s standard lift blades instead.
• Balance: New blades are pre-balanced, but always check with a blade balancer after installation. An unbalanced blade causes vibration and damages the spindle.

Should You Buy It

Buy this set if you own a 72-inch Bad Boy mower and want genuine OEM mulching performance with fine, even clippings that decompose quickly. It’s a solid value at $77.99 for three blades, but skip it if you frequently bag or side-discharge—these are purpose-built for mulching only.
