KOFINAM Replacement Lawn Mower Blades 3-Pack for 54" Bad Boy OEM 038-0005-00 — Hardened Steel, Balanced Cut

KOFINAM replacement blades (3-pack) are precision-fit steel mower blades designed to replace Bad Boy OEM 038-0005-00 on 54" decks for consistent, clean cuts.

When your mower's blade wears or chips, turf quality and trimming speed suffer. These KOFINAM blades match the dimensions and center hole of the Bad Boy 038-0005-00 design so they install cleanly on 54" decks such as the MZ Magnum series. Made from hardened steel and sold in a three-pack, they give you a ready supply for seasonal replacements and even wear rotation.

How do these blades match my Bad Boy mower?

These blades mirror the OEM form and fit specifications required for a proper install. That means you get the same mounting hole size and cutting span as the original part to preserve deck balance and blade overlap.

• Length: 18-3/4" to match deck reach
• Width: 2-1/2" for the original cutting profile
• Thickness: 0.204" to maintain strength and safety
• Center hole: 5/8" to fit standard Bad Boy spindle bolts
• Designed for 54" mower decks like MZ Magnum

What performance can I expect from these KOFINAM blades?

These blades are stamped from high-quality steel and heat-treated to resist premature wear and bending. Expect steady grass shearing and reduced tear when blades are kept sharp and mounted correctly, improving overall cut quality and clippings dispersion.

• High-strength steel for longer edge life
• Balanced profile minimizes vibration during operation
• Sharp, uniform edges for even cutting patterns
• Pack of three lets you replace all blades or keep spares

How do I install and maintain these replacement blades?

Installation follows the same steps as OEM blades: disconnect spark, remove old blades, match orientation, torque to manufacturer specs, and balance if needed. Regular inspection and occasional sharpening will extend service life and protect your deck components.

• Always disconnect the battery or spark plug before work
• Match rotation direction and blade orientation exactly
• Torque blade bolts to the mower manufacturer’s recommended setting
• Sharpen and check balance after every few uses or when nicked

What warranty and support come with the blades?

KOFINAM backs these replacement blades with a limited after-sales warranty to give buyers confidence. If a defect appears within the stated period, contact customer support for assistance and replacement guidance.

• 6-month warranty coverage from purchase date
• Email support available for fitment or defect questions
• Replacement or guidance offered for verified manufacturer issues

Who is this for? These KOFINAM replacement blades are aimed at owners of 54" Bad Boy mowers — especially those with MZ Magnum decks — who want OEM-compatible parts without the OEM price. They suit homeowners, landscapers, and maintenance crews who need reliable, stockable spares to keep a fleet or single mower operating at peak trim quality.
