Oregon 3 Pack 91-623 High Lift Mower Blade for Ferris 481711 A48185 36" 52"

What It Is

This Oregon 3 Pack 91-623 high-lift mower blade is designed for Ferris commercial zero-turn mowers with 36" or 52" decks. The high-lift profile increases airflow for better grass discharge and bagging performance, making it ideal for thick or wet grass.

Fitment & Compatibility

• Deck size: Works with Ferris 36" and 52" cutting decks (not 48" or 61").
• OEM cross-reference: Replaces Ferris part numbers 481711 and A48185.
• Measurements: Each blade is 18.5" long, 2.5" wide, with a 5/8" center hole and 7/16" depth. Star pattern on the center hole ensures proper alignment.
• Check before buying: Confirm your Ferris model uses two blades (36" deck) or three blades (52" deck). This pack covers one set for a 52" deck or covers a 36" deck with one spare. Not compatible with EGO brand mowers despite the listing brand—this is an Oregon blade, not EGO.

Key Things to Know

• Installation difficulty: Moderate—requires a socket wrench and torque wrench (60-70 ft-lbs recommended). Star pattern prevents incorrect mounting, but always check blade orientation before tightening.
• Quality note: Oregon blades are a reputable aftermarket brand, but some users report slightly thinner steel than OEM Ferris blades. Expect shorter lifespan in heavy-use commercial conditions.
• Common gotcha: The high-lift design creates more drag, which can reduce engine efficiency and increase fuel consumption. Not ideal for mulching—use low-lift blades for that.
• Pack contents: Three blades, but no hardware included. Reuse your existing bolts and washers, or buy new ones separately.

Should You Buy It

Buy this if you own a Ferris 36" or 52" zero-turn and prioritize bagging or side-discharge performance over mulching. It’s a solid budget-friendly alternative to OEM blades, but if you cut daily commercially, consider OEM for longer wear. Skip it if you need mulching blades or have a different deck size.
