483317 Scag OEM Mower Blade

What It Is

The 483317 is an OEM (original equipment manufacturer) mower blade from Scag, designed for use on commercial zero-turn mowers. It’s a standard-duty cutting blade intended for general grass cutting, not mulching or bagging.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This blade fits Scag 48-inch, 52-inch, and 61-inch cutting decks (check your specific model—common fits include Scag Turf Tiger, Cheetah, and Wildcat).
• OEM vs aftermarket: This is a genuine Scag part, so it will match factory specs exactly. Aftermarket blades may be cheaper but can vary in thickness, balance, or steel quality.
• Measurements: Blade length is 21.5 inches, center hole diameter is 5/8 inch, and the blade is 0.203 inches thick. Measure your old blade to confirm these numbers—don’t rely solely on model number if your deck has been modified.
• Not universal: Will not fit most residential lawn tractors or other brands (John Deere, Husqvarna, etc.) without adapter kits.

Key Things to Know

• Quality: Scag OEM blades are made from heat-treated, high-carbon steel. They hold an edge well but will dull faster in sandy or rocky soil.
• Installation: Easy for anyone with basic tools—remove the old blade, install the new one with the “wing” pointing up toward the deck, and torque the bolt to 70-90 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Balance: OEM blades are pre-balanced. After installing, spin the blade by hand to check for wobble—if it’s off, the blade can vibrate and damage the spindle.
• Gotcha: The 483317 is a “high-lift” design, meaning it creates more suction for better discharge. This also increases wear on the blade tip and requires more engine power—don’t use on underpowered decks.

Should You Buy It

Buy this if you own a Scag zero-turn with a 48-61 inch deck and want a direct, no-guesswork replacement that matches factory performance. It’s ideal for commercial or heavy residential use where reliability and cut quality matter more than cost. Skip if you need a mulching or low-lift blade, or if your deck is from another brand.
