Scag 3 Made in USA, Heavy Duty, Heat Hardened, Replacement Blade Blade Part # 481708, 482879, 48111, A48111

What It Is

This is a high-end, USA-made replacement blade for Scag commercial zero-turn mowers. Designed for heavy-duty cutting in high-use or rough conditions, it uses heat-hardened steel to stay sharp longer than standard blades.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits 48", 52", 61" Scag decks. Confirm your deck’s exact size—blade length varies by model.
• Part numbers cross-reference: 481708, 482879, 48111, A48111. These are Scag OEM numbers; aftermarket versions exist but this is the genuine Scag blade.
• Measurement: Blade length is typically 20.5 inches (verify your current blade’s length). Center hole diameter is 1 inch, with a 1/4-inch offset.
• Brand fit: Scag only—will not fit other brands without modification. If you have a Scag mower, this is a direct OEM replacement.

Key Things to Know

• Quality: Made in USA from heat-hardened steel—much more durable than standard stamped blades. Expect 2–3x longer life in abrasive or sandy soil.
• Installation: Simple bolt-on, but use a torque wrench. Scag spec is 70–90 ft-lbs. Over-tightening can warp the blade or strip the spindle.
• Common gotcha: These blades are thicker than many aftermarket options. Verify your spindle bolts are long enough to engage fully—old bolts may need replacement.
• Balance: Always balance after sharpening. Even a small imbalance stresses spindles and bearings. Use a blade balancer.

Should You Buy It

Yes—if you own a Scag commercial mower and cut tough grass, debris, or uneven ground. It’s overkill for light residential use, but for pros or heavy property owners, the durability and USA build justify the price. If your deck is under 48 inches or you’re on a budget, look at standard Scag blades instead.
