How do these blades affect cutting quality and deck balance?

Using matching OEM blades helps preserve the deck’s original cutting geometry and keeps the spindle load balanced. When blades are the correct length, weight, and hole placement, they reduce vibration and wear on spindle bearings and pulleys. Fresh blades also produce a cleaner cut, improving turf appearance and reducing the need for a second pass.

• Factory dimensions ensure consistent blade arc and overlap.
• Balanced blades minimize vibration and spindle stress.
• Sharp OEM edges improve cut quality and grass health.
• Three-blade set replaces all blades on many 52" decks at once.

What materials and construction should I expect from these OEM Scag blades?

Scag OEM blades are stamped and heat-treated for strength and wear resistance consistent with factory specifications. They’re built to withstand mowing stresses while retaining an edge through a typical cutting season. Because they’re genuine Scag parts, they match the deck’s engineered tolerances rather than being generic aftermarket copies.

• Stamped steel construction with factory heat treatment.
• Precision hole pattern for secure mounting and balance.
• Paint- or coating-finishes that resist surface rust before first use.
• Supplied in a convenient three-pack to service full 52" decks.

How should I install and maintain these replacement blades?

Installation is straightforward but requires correct torque and safety steps. Raise and secure the mower, remove old blades one at a time, note their orientation, then install each OEM blade with the cutting edge facing the same direction. Regular inspection and sharpening as needed will keep cutting performance at its best.

• Always disconnect spark plug and secure mower before service.
• Install blades with correct orientation and torque per Scag specs.
• Check and re-torque after a few hours of operation if recommended.
• Sharpen or replace blades when nicks, bends, or excessive wear appear.
