High Lift Mower Blades 14.49" Replacement for Bad Boy 038-4222-00 Fits 42 Inch Deck MZ, MZ Magnum, Rambler, Maverick HD, Circle Center Hole 3PCS with Bolts and Washers

What It Is

A set of three 14.49-inch high-lift mower blades designed for 42-inch Bad Boy zero-turn mowers (MZ, MZ Magnum, Rambler, Maverick HD). The high-lift profile increases airflow under the deck for superior grass discharge and bagging performance, especially in thick or wet grass.

Fitment & Compatibility

• Deck size: 42-inch cutting deck (requires 3 blades, 14.49" length each).
• Center hole: Circle center hole (not star or oval) – measure your spindle shaft to confirm.
• OEM replacement: Direct substitute for Bad Boy part 038-4222-00. Fits MZ, MZ Magnum, Rambler, Maverick HD models with 42" decks.
• What to check before buying:
  1. Measure existing blade length (from tip to tip) – must be exactly 14.49".
  2. Verify center hole shape is round (not keyed/star).
  3. Confirm deck is 42" (not 48" or 54").
  4. Ensure your mower uses 3 blades (some 42" decks use 2).
• Included: Bolts and washers (check thread size matches your spindle – typically 5/16"-24 or 3/8"-24).

Key Things to Know

• High lift = more power draw: Expect slightly higher engine load and reduced run time vs. standard blades, especially in tall grass.
• Installation tip: Torque bolts to 30-50 ft-lbs (check your manual). Over-tightening can strip spindles; under-tightening risks blade detachment.
• Lift quality: Users report noticeably better bagging and discharge compared to OEM Bad Boy blades, but they may leave a slightly rougher cut in dry conditions.
• Common gotcha: The included washers may not fit all spindles – keep your original hardware if the new ones are too thick or thin.

Should You Buy It

Yes, if you own a 42-inch Bad Boy MZ, MZ Magnum, Rambler, or Maverick HD and prioritize bagging or side-discharge performance over a perfectly manicured finish. Avoid if you mostly mulch or cut dry, short grass – a standard-lift blade will be more fuel-efficient and give a smoother cut.
