What It Is

This is a 3-pack of heavy-duty high-lift blades designed for 48-inch zero-turn mowers from Ariens, Gravely, and Ferris, specifically the Lazer Z, HP, ZT, and HD series. The high-lift design increases airflow under the deck for superior grass clipping discharge and bagging performance, making it ideal for thick or wet grass.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch cutting deck and that the blade measurements match:

• Length: 18.25 inches (center hole to tip)
• Width: 2.5 inches
• Center hole: 1 inch diameter (some models may need a centering bushing)
• OEM cross-references: 103-2527, 1520843, 5020843, 1520843S, 103-6583, 1-7036, 04919100, 00273000

Double-check your deck model (e.g., A48, 48HD) and spindle design—some newer decks use a different bolt pattern. Measure your current blade if uncertain, as aftermarket blades can vary slightly in thickness or hole alignment.

Key Things to Know

• Quality: These are heavy-duty steel blades, but some users report they are slightly thinner than OEM. Inspect for balance before installation.
• Installation: Requires a torque wrench (60-80 ft-lbs) and a blade removal tool. Use thread locker on the spindle bolt to prevent loosening.
• Performance: High-lift blades create more suction, which improves bagging but can increase engine load and noise. Not ideal for mulching.
• Gotcha: The blue coating may peel over time; this is cosmetic and doesn’t affect function.

Should You Buy It

If you own a compatible 48-inch Ariens, Gravely, or Ferris zero-turn and need a cost-effective replacement for bagging or discharge cutting in thick grass, this 3-pack offers solid value. Skip it if you primarily mulch or want OEM thickness—stick with factory blades for that use.
