MaxPower 3-Blade Replacement Set for 60" Exmark Decks — 20.5" x 2.5" USA Made, Pre-Sharpened Powder-Coated

MaxPower 561139B is a three-blade replacement set engineered for 60-inch Exmark decks, matching OEM fit and durability while being made in the USA.

If your commercial or residential mower needs a reliable blade swap, this 3-pack from MaxPower gives you full deck coverage with parts designed to meet or exceed the original equipment specifications. Each blade is pre-sharpened and powder-coated for corrosion resistance during storage and transport; the coating wears off on the first cut to reveal a precision edge. The set is compatible with many Exmark models and replaces OEM numbers 103-6403, 103-6403-S, and 140-1240 — but you should still confirm the OEM number in your owner’s manual before ordering.

Which Exmark models will these blades fit?

These blades are sized and drilled to fit a wide range of Exmark lawn tractors and zero-turn mowers with a 60-inch cutting deck. Compatibility covers several model families, from the Laser series to Turf Ranger and Ultra Cut. Always verify the original blade part number for a positive match.

• Compatible model groups: CT, Front Runner, Laser HP, Laser Z variants, Phaser, Pioneer, Quest, SP, Turf Ranger, Ultra Cut, Vantage
• Replaces OEM part numbers: 103-6403, 103-6403-S, 140-1240
• Confirm fit by matching OEM number in your mower’s manual

What are the exact dimensions and mounting details?

Each blade in the pack measures 20-1/2 inches long and 2-1/2 inches wide, with a center mounting hole sized to standard Exmark hubs. The 15/16-inch center bore aligns with the factory spindle hardware used on many 60-inch decks. These dimensions ensure proper clearance, rotation, and blade tip radius for recommended deck performance.

• Blade length: 20-1/2 inches
• Blade width: 2-1/2 inches
• Center hole diameter: 15/16 inch
• Sold as a set of three blades — full deck replacement

How are MaxPower blades finished and prepared for use?

MaxPower blades are manufactured to match OEM strength and balance, then sharpened at the factory for immediate use. A protective powder coat is applied to prevent rust during storage; this coating will be removed during the first mowing to reveal the factory-sharpened cutting edge. The result is a blade ready to deliver straight cuts once installed and run briefly.

• Factory-sharpened edge for immediate operation
• Powder-coated finish protects during transport and storage
• Made in the USA to OEM-like tolerances and materials
• Balanced to reduce vibration and spindle wear

Who is this for? Landscapers, property owners, and maintenance crews who operate Exmark machines with 60-inch decks and need a dependable, ready-to-install blade set will find this MaxPower 3-pack convenient and cost-effective. It’s aimed at users replacing all three deck blades at once to restore cutting performance and balance. If you are unsure whether these blades match your mower, check the OEM number stamped on your old blade or consult your owner's manual before purchase.
