Scag 483316 OEM Mower Blade

What It Is

The Scag 483316 OEM Mower Blade is a factory replacement blade designed specifically for Scag commercial zero-turn mowers. It’s a high-lift blade optimized for bagging and side-discharge cutting in heavy grass or tall turf.

Fitment & Compatibility

Before buying, verify your mower deck size and model. This blade fits Scag 48-inch and 52-inch decks, including the Cheetah, Tiger Cat, Turf Tiger, and Wildcat series. Check your owner’s manual or existing blade for the part number 483316. The blade measures 20.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and a 7/16-inch offset. It is an OEM part—aftermarket alternatives may differ in thickness, heat treatment, or balance. If your deck uses a different blade length or hole pattern (e.g., 3-in-1 or mulching blades), this won’t fit.

Key Things to Know

• Quality: OEM Scag blades are made from hardened steel with a consistent edge profile. They hold an edge longer than most aftermarket options but cost more.
• Installation difficulty: Easy—requires a socket wrench and torque wrench. Tighten to 70–90 ft-lbs. Always replace in sets (all blades on the deck) to avoid vibration.
• Common gotchas: High-lift blades create more suction and can throw debris farther—use a discharge chute. They dull faster in sandy or abrasive soil. Never sharpen more than 1/8 inch off the cutting edge.
• Balance: New OEM blades are factory-balanced. After sharpening, re-check balance to prevent deck wobble and bearing wear.

Should You Buy It

If you own a Scag commercial mower with a 48- or 52-inch deck and primarily bag or side-discharge tall grass, this OEM blade delivers reliable cut quality and longevity. It’s not the cheapest option, but for pros who need consistent performance and minimal downtime, it’s worth the premium. Avoid it if you mulch frequently—you’ll want a low-lift or mulching blade instead.
