481711 Scag OEM Mower Blade

What It Is

The Scag OEM 481711 is a 21-inch, high-lift mower blade designed for Scag commercial zero-turn and walk-behind mowers, optimized for bagging and high-volume grass discharge in dense or wet conditions.

Fitment & Compatibility

• Deck size: Fits 48-inch and 61-inch Scag decks (e.g., Turf Tiger, Cheetah, V-Ride, Patriot) that use 3-blade configurations with a 5/8-inch center hole.
• Model check: Confirm your deck part number (e.g., 483456, 483457) or verify the blade’s 21-inch length matches your current blade. Measure from center hole to tip, then double.
• OEM vs aftermarket: OEM ensures exact hole alignment, thickness (0.204 inch), and heat treatment. Aftermarket blades may vary in balance or lift height, risking poor cut or vibration.
• Physical check: Ensure no spindle interference; the high-lift design can hit deck baffles on older models if the blade is slightly bent or deck is modified.

Key Things to Know

• Quality: Made from hardened steel with a fusion-coated edge for wear resistance; lasts 2–3x longer than standard blades under heavy use.
• Installation: Use a torque wrench to tighten to 70–90 ft-lbs. The high lift creates more drag, so a loose blade can damage the spindle.
• Common gotchas: The 21-inch length is critical—using a 20.5-inch blade on a 61-inch deck will leave uncut strips. Always replace all three blades at once to maintain balance.
• Performance: Best for bagging or tall grass; not ideal for mulching—the high lift throws clippings far, not down.

Should You Buy It

Buy this if you run a Scag commercial mower with a 48- or 61-inch deck and need OEM-grade durability for bagging or heavy, wet grass. Skip it if you primarily mulch or want a cheaper aftermarket alternative—this blade is built for pros who can’t tolerate downtime.
