3PK Mower Blade for 48in Decks — 16.5in length, 5/8in center hole, 1in air lift

3PK USA 48" mower blade is a heavy-duty, 16-1/2" replacement blade built to fit Scag, Hustler, John Deere, Toro, and Snapper 48-inch decks that require a 5/8" center hole and 1" air lift.

If your zero-turn or riding mower needs a durable blade that matches factory fit and performance, this 3PK USA replacement is engineered to the same key dimensions as many OEM parts. It fits a long list of part numbers from leading brands so you can restore cutting quality without hunting for an exact OEM model. The blade is made to standard length, thickness, and lift specifications to keep deck balance and cut uniformity.

Will this blade fit my 48" deck and mounting hardware?

Check three main deck measurements: overall blade length, center hole diameter, and air lift height. This 3PK blade measures 16-1/2" overall, has a 5/8" center hole, and provides a 1" air lift, matching many 48" commercial and residential decks that list those specs.

• Blade length: 16-1/2"
• Center hole: 5/8" diameter
• Air lift: 1" (for correct airflow and mulching)
• Thickness: 0.250" to preserve balance and durability

How does blade dimension affect cutting and deck balance?

Blade thickness and length influence rigidity and vibration; using the correct size maintains deck balance and smooth operation. The 0.250" thickness reduces flex under load while the matched length and lift keep even grass discharge and reduce scalping risk when installed correctly.

• 0.250" thickness for reduced flex and longer life
• 16-1/2" length aligns with many OEM blade spacing and clearances
• 1" air lift helps maintain lift for cleaner cuts and bagging
• Correct center hole avoids adaptor or spacer modifications

Which OEM part numbers and brands are compatible with this blade?

This 3PK blade is designed as a direct replacement for a wide range of OEM references across multiple brands, making it a practical choice when original parts are obsolete or expensive. Confirm compatibility with your mower's parts list or service manual before purchase.

• Scag: 48110, 481706, 482877 and related A-48110/A48184 references
• Hustler: 601014, 601123 and variants (X, Y) plus 795757 family
• John Deere: AM104489, M73509 and TCU series numbers
• Toro and Snapper part cross-references included for many 48" decks

What should I expect during installation and maintenance?

Installation follows standard blade-change procedures: safely support the mower, remove the old blade, and torque the blade bolt to manufacturer specs. Routine checks for balance, nicks, and secure mounting will extend blade life and protect the deck spindles.

• Mount using 5/8" center bolt and correct torque
• Inspect and sharpen or replace if heavy damage appears
• Check blade balance after sharpening to prevent vibration
• Replace as a matched set when replacing multiple blades on multi-blade decks

It's ideal when you want a cost-effective, properly sized blade that restores cutting performance and keeps your deck running smoothly without modifying mounting hardware.
