Oregon 6PK 92-035 Heavy Duty Blades for 72" Scag 48112, 481709, 482788, 482882

What It Is

This is a set of six heavy-duty lawn mower blades designed for 72-inch Scag commercial zero-turn mowers. They are intended for high-use, demanding mowing conditions where durability and consistent cut quality are critical.

Fitment & Compatibility

Before buying, confirm your mower has a 72-inch deck and that the blade part numbers match your spindles. These blades replace Scag OEM numbers 48112, 481709, 482788, and 482882. Measure your existing blade length (should be 22 inches), center hole diameter (typically 5/8 inch), and thickness (0.250 inch) to verify fit. These are aftermarket replacements—not genuine Scag—so check that the blade orientation and lift pattern match your deck’s design. Not for use on residential or smaller commercial decks.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand; these blades are made from hardened steel with heat-treated edges for longer life in abrasive or rocky conditions.
• Installation: Standard swap—no special tools beyond a socket wrench and blade removal tool. Torque bolts to 70-90 ft-lbs. Always sharpen after first 10 hours of heavy use.
• Gotcha: The heavy-duty design adds weight, which can strain spindles if your deck already has worn bearings. Inspect spindles before installing.
• Gotcha: These blades may produce a slightly rougher cut than OEM on fine turf due to the thicker profile. Best for rough cut or commercial fields.

Should You Buy It

Buy these if you run a 72-inch Scag commercial mower and need a durable, cost-effective alternative to OEM blades for high-volume or abrasive mowing. Avoid them if you demand a pristine finish on manicured lawns or have older spindles that may not handle the extra weight.
