TENGMUJX High-Lift Mower Blades for Bad Boy 48" MZ / MZ Magnum — 16½" Length, 5/8" Center Hole, Hardened Steel

TENGMUJX 038-4825-00 high-lift replacement mower blades restore cutting performance on Bad Boy 48" MZ and MZ Magnum decks with a 16½" length and 5/8" center hole.

These high-lift blades are engineered to match the fit and function of Bad Boy's 038-4825-00 OEM part for 48-inch fabricated decks. Built from hardened steel with a 0.203" thickness, the blades create strong airflow for improved grass lift and bagging while maintaining the correct width and hole pattern for direct installation. They are suited for homeowners and landscapers who want a cost-effective, reliable blade swap to revive mowing performance without modifying the mower.

How do these blades improve my lawn's cut?

High-lift blades generate more upward airflow beneath the deck, which lifts grass upright before the blade severs it. That cleaner presentation helps produce a more even, professional-looking finish, especially when bagging or mulching. The blade geometry is designed to balance lift with a consistent cutting swath to avoid striping or missed sections.

• High-lift profile increases suction for cleaner bagging and discharge.
• 16½" cutting surface matches the deck's intended coverage.
• 0.203" thickness resists bending and holds edge better under load.

Will these blades fit my Bad Boy 48" MZ or MZ Magnum mower?

Yes — they are produced to replace OEM 038-4825-00 for Bad Boy 48" MZ and MZ Magnum models using a 5/8" center mounting hole. You should verify your mower uses a fabricated Toro-style 48" deck and the same mounting pattern before purchase. Fit is intended to be bolt-on without adapters when matched to the specified models.

• Replaces OEM number: Bad Boy 038-4825-00.
• Center hole diameter: 5/8" for direct hub compatibility.
• Blade length: 16½" and width: 2½" to match factory swath.

How durable and easy to install are these blades?

TENGMUJX manufactures these blades from hardened steel with strict quality controls to provide consistent dimensions and edge life. The 0.203" plate thickness gives strength against flex and wear during heavy use, while the finished mounting hole aligns precisely to simplify replacement. Installation is straightforward with common tools and basic mechanical knowledge; follow torque specs from your mower manual.

• Material thickness 0.203" for improved durability and edge retention.

What should I consider before buying these blades?

Confirm your mower model, deck size, and mounting bolt diameter match the listed specifications. Inspect blades regularly for nicks and balance after installation; replace in matched pairs or sets to maintain even blade loading. Also decide whether you prioritize bagging, mulching, or side-discharge to ensure the high-lift profile aligns with your mowing style.

• Verify mower model: Bad Boy 48" MZ or MZ Magnum fabricated deck.
• Check center hole: 5/8" and thickness: 0.203" to match spindle hardware.
• Replace blades as matched sets to maintain balance and performance.
