038-4820-00 038-4826-00 Blades Fit for 48" Bad Boy MZ Magnum ZT CZT Elite Maverick Mower Deck, Replaces 103-6583-S 11211101 High Lift Notched 3 Pack

What It Is

This 3-pack of high-lift notched blades is designed for 48" cutting decks on Bad Boy MZ Magnum, ZT, CZT, Elite, and Maverick zero-turn mowers. They replace OEM part numbers 103-6583-S and 11211101, offering improved grass lift and discharge for thick or wet grass.

Fitment & Compatibility

• Deck size: Only fits 48" Bad Boy decks—verify your deck width before buying.
• Model check: Compatible with MZ Magnum, ZT, CZT, Elite, and Maverick series. Double-check your specific model year, as older or newer variants may differ.
• OEM vs aftermarket: These are aftermarket replacements for OEM 103-6583-S and 11211101. Measure your existing blade length, center hole diameter, and thickness to confirm match—typical specs are 18.5" length, 1" center hole, 0.25" thickness.
• Notched design: The notch on the blade’s trailing edge is for spindle clearance on Bad Boy decks—ensure your deck uses notched blades (most 48" Bad Boy models do).

Key Things to Know

• High-lift design increases suction for better bagging and discharge, but creates more drag—expect slightly higher engine load and fuel consumption.
• Installation is straightforward: remove one bolt per blade (usually 15/16" or 7/8" socket). Torque to 70–90 ft-lbs; overtightening can warp the blade.
• Common gotcha: These blades are sharp from the factory—use gloves and a blade removal tool to avoid injury. Also check blade balance after install; minor imbalance can cause vibration.
• Durability note: At this price point, they’re mid-range. Expect to replace after 25–50 hours of use, especially in sandy or rocky conditions.

Should You Buy It

If you own a 48" Bad Boy zero-turn and need a reliable, affordable replacement for OEM blades, this 3-pack delivers solid performance for the price. It’s best for residential users cutting thick or damp grass who want better lift than standard blades but don’t need commercial-grade longevity. Avoid if you have a different deck brand or need blades for dry, fine-cut lawns.
