Will these blades fit my Exmark mower?

These blades are made to be compatible with Exmark OEM part numbers including 103-6403, 103-6403-S, and 103-6403-SU, and several Encore listings. They were sized to match 60-inch decks on numerous Exmark series, so confirmation of your model and deck size is recommended before ordering.

• Specifically for 60" cutting decks requiring a 20.5" blade length
• 15/16" center hole fits standard Exmark spindle bolt pattern

How does the high-lift profile affect cutting performance?

The high-lift contour generates stronger upward airflow beneath the deck, which helps stand grass upright for a cleaner cut and more efficient bagging or side discharge. This profile also helps move clippings through the deck more aggressively, reducing clumps and improving overall finish when mowing dense turf.

• Increases deck airflow for improved bagging and discharge
• Helps prevent clumping in thick or wet grass conditions
• Maintains a sharper, uniform cut when properly balanced and installed

What are the exact dimensions and build details?

Each 8TEN LawnRAZOR blade measures 20.5 inches long and 2.5 inches wide with a thickness near 0.197 inches. The blades feature the common 15/16" center aperture so they align with Exmark spindle hardware. Quality steel construction and a consistent thickness keep balance and reduce vibration when mounted correctly.

• Length: 20.5 inches; Width: 2.5 inches; Thickness: 0.197 inch
• Center hole: 15/16" to match Exmark spindles
• Sold as a convenient 3-pack for multi-blade commercial decks

How should I install and maintain these blades?

Installation follows standard mower blade procedures: disconnect the spark plug, tilt mower to access the deck, remove old blades, and torque the blade bolts to manufacturer specs. Regular sharpening, balancing and timely replacement are key to preserve deck health and cutting quality.

• Always disconnect spark and stabilize mower before blade work
• Torque bolts to Exmark-recommended settings and check balance after sharpening
• Replace blades as a matched set to reduce vibration and uneven wear

Who is this for: Landscapers, grounds crews and homeowners using Exmark 60" mowers who need a dependable high-lift blade replacement are the ideal users for the 8TEN LawnRAZOR 3-pack. If you operate any of the compatible Exmark series or Encore models and want to restore bagging efficiency, reduce clumping, and maintain a professional finish, these blades provide a specification-matched, budget-friendly alternative to OEM parts.
