038-4221-00 High Lift Blades Fit for Bad Boy 42" Deck Mower MZ, MZ Magnum, CZT, Rambler, Replace 038-4226-00 (3 Pack)

What It Is

This 3-pack of high-lift blades (model 038-4221-00) is designed for Bad Boy 42-inch zero-turn mowers, including the MZ, MZ Magnum, CZT, and Rambler series. They replace OEM part 038-4226-00 and are built for improved grass discharge and bagging performance on residential or commercial properties.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches wide (measured blade tip to tip). These blades fit Bad Boy models listed above but not all 42" decks from other brands. The blade length is 18.5 inches, center hole is 1 inch, and the spindle hole spacing is 4.25 inches. If your current blade measures these same specs, it will fit. Always compare to your existing blade—brand/model mismatch is the top return reason.

Key Things to Know

• Installation: Easy—just lift the deck, remove the old blade bolt, and swap. Use a torque wrench to tighten to 70-90 ft-lbs. No special tools needed.
• Quality: High-lift design creates strong suction for better mulching and bagging, but it also increases engine load slightly. Expect a bit more noise and vibration than standard blades.
• Common gotchas: These blades are sold as a set of three—make sure your deck uses three blades (most 42" Bad Boy decks do). Some users report that the blades are slightly thinner than OEM, which can reduce lifespan on rocky terrain.
• Sharpness: They come sharp but not razor-edged. A quick touch-up with a file before first use can improve cut quality.

Should You Buy It

If you own a Bad Boy 42" ZT and want better lift for thick grass or bagging, this is a solid, affordable upgrade over standard OEM blades. Avoid if you mow very rocky or debris-heavy lawns—the thinner steel may chip faster. For most homeowners and light commercial use, the price-to-performance ratio is excellent.
