038-4825-00 Mower High Lift Blades Fit for Bad Boy 48" MZ, MZ Magnum Lawn Mower Blades Length 16 1/2" Center Hole Size 5/8"

What It Is

This is a set of high-lift replacement blades for 48-inch Bad Boy MZ and MZ Magnum zero-turn mowers. Designed for improved grass discharge and bagging, they create more upward airflow than standard blades, making them ideal for thick or damp grass.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Fits only 48-inch cutting decks (not 42", 54", or 60").
• Blade dimensions: Length must be exactly 16 1/2 inches, center hole 5/8 inch (these blades match). Measure your old blade end-to-end and the center hole diameter.
• Model check: Confirmed for Bad Boy MZ and MZ Magnum models with 48" decks. Not guaranteed for other Bad Boy series (e.g., Outlaw, ZT) – cross-reference your owner’s manual or measure your current blade.
• OEM vs aftermarket: These are Lift brand aftermarket blades, not OEM Bad Boy parts. They should fit and function similarly but may differ slightly in thickness or balance.

Key Things to Know

• Performance trade-off: High-lift blades improve bagging and discharge but require more engine power and may leave uneven stripes on dry, thin grass. Not ideal for mulching.
• Installation: Easy DIY job – lift deck, remove center bolt, swap blades. Use a torque wrench to tighten bolts to 40-55 ft-lbs (check your mower’s spec). No special tools needed.
• Balance check: Aftermarket blades can be slightly out of balance. Spin them on a blade balancer before installing to avoid vibration and deck damage.
• Durability: Reviewed as decent for the price – expect 1-2 seasons of residential use. Not as thick or hardened as OEM Bad Boy blades (which cost more).

Should You Buy It

Buy these if you own a 48-inch Bad Boy MZ or MZ Magnum, want better bagging or discharge in tall/wet grass, and don’t mind a bit more engine strain. Skip them if you primarily mulch, have a different deck size, or need OEM-level durability for commercial use – in that case, stick with genuine Bad Boy blades.
