Keycci 038-4826-00 High Lift Blades Compatible with Bad Boy MZ Magnum ZT CZT Elite Stand-On Mower, Lawn Mower Blades Fit for Bad Boy 48'' Deck, 3 Pack

What It Is

The Keycci 038-4826-00 high lift blades are aftermarket replacements designed for Bad Boy mowers with 48-inch decks, including MZ Magnum, ZT, CZT Elite, and stand-on models. Their high-lift profile increases airflow under the deck for better grass discharge and bagging performance, making them ideal for tall or damp grass.

Fitment & Compatibility

Before buying, confirm your Bad Boy mower has a 48-inch deck (measure from blade tip to tip across the deck). These blades replace OEM part 038-4826-00. They are not compatible with 42-inch, 54-inch, or 60-inch decks. Check your spindle hole size (usually 5/8” or 7/8” center hole on Bad Boy models) and overall blade length—these are 18.75 inches long, 2.5 inches wide, with a 5/8-inch center hole and 0.25-inch thickness. Verify your deck’s blade bolt pattern matches (typically a single bolt with a washer). If your mower has a different spindle hole or offset, these won’t fit.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and possibly a blade removal tool. Always disconnect the spark plug first.
• Quality: Most users report these are balanced out of the box, but double-check with a blade balancer to avoid vibration. The steel is heat-treated and coated for rust resistance, though not as thick as OEM blades.
• Common gotcha: High lift blades increase engine load and may reduce fuel efficiency or lift the mower on slopes. They also throw debris farther—wear eye protection and avoid operating near gravel or loose objects.
• Sound: Expect a louder, more aggressive cutting noise compared to standard blades.

Should You Buy It

If you own a Bad Boy 48-inch deck mower and need a budget-friendly blade for heavy bagging or mulching in thick grass, this three-pack offers good value at ~$13 per blade. It’s not for you if you prefer OEM durability, need a standard lift blade for flat terrain, or have a non-Bad Boy deck. For the price, it’s a solid upgrade over worn factory blades.
