Scag 482877 Pack of 3 Blades

What It Is

This is a pack of three OEM Scag 482877 replacement blades designed for Scag commercial walk-behind mowers. They’re intended for standard cutting and mulching on 36" and 48" decks used in professional landscaping or heavy residential duty.

Fitment & Compatibility

• Deck size: Fits Scag 36" and 48" decks only. Not for 52" or 61" decks.
• Model fit: Compatible with Scag SWZ (36"), STT (48"), and SZ (48") series. Check your mower’s serial number or parts diagram to confirm.
• OEM vs aftermarket: These are genuine Scag parts, not aftermarket. They match original dimensions and hole pattern exactly.
• Measurements: Blade length is 18.5 inches, center hole is 5/8 inch diameter, and blade thickness is 0.25 inch. Verify your current blade matches these before ordering.
• What to check: Count your blades—you need three for a 36" deck (two outer, one center) or three for a 48" deck (two outer, one center). Also confirm your spindle bolt size (usually 5/8" or 3/4") to ensure the hole fits.

Key Things to Know

• Quality: OEM Scag blades are heat-treated and balanced for durability. They cut cleanly and resist bending on rocky terrain.
• Installation difficulty: Easy—requires a socket wrench and torque wrench. Torque spindle bolts to 70-80 ft-lbs. Use thread locker if bolts are worn.
• Gotcha: The center blade on 36" decks is shorter than the outer blades, but this pack includes three identical 18.5" blades. Check your deck; some models use a shorter center blade (14"). If yours does, this pack won’t fit.
• Sharpening: These can be sharpened 2-3 times before replacement. Don’t sharpen if they’re bent or chipped—replace immediately.

Should You Buy It

Buy this if you own a Scag 36" or 48" walk-behind with standard-length blades and need a fresh set for consistent cut quality. It’s a solid value for OEM durability, but skip it if your deck uses a shorter center blade or if you’re on a tight budget—aftermarket sets run cheaper.
