Scag 3PK Genuine OEM Cutter Blade 21" (1/4") 482881

What It Is

This is a set of three genuine Scag OEM 21-inch cutter blades (part number 482881) designed for Scag commercial zero-turn mowers. They are intended for heavy-duty cutting on large properties, such as golf courses, parks, or commercial landscaping accounts.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: These blades fit Scag decks that require three 21-inch blades (1/4-inch thick). Common decks include 61-inch and 72-inch models, but confirm your deck’s blade count and spacing.
• Model check: Compatible with many Scag Turf Tiger, Wildcat, and Cheetah models. Use Scag’s online parts lookup or your owner’s manual to confirm 482881 is listed for your specific unit.
• OEM vs aftermarket: These are genuine Scag blades, not aftermarket. They match factory specs exactly, so no modification or adapter is needed. If you’ve used aftermarket blades before, note that OEM blades often have different hole patterns or thicknesses.

Measure your current blade’s length, thickness, center hole diameter, and bolt pattern. Scag 482881 blades have a 21-inch length, 1/4-inch thickness, and a 5/8-inch center hole. If your deck uses a different hole size or pattern, these won’t fit.

Key Things to Know

• Quality: Genuine Scag blades are heat-treated and balanced for longer edge life and less vibration than generic options. Expect 2-3 times the lifespan of budget blades under normal use.
• Installation difficulty: Straightforward if you have a torque wrench and a blade removal tool. Torque bolts to 70-90 ft-lbs (check your manual). Use thread locker if recommended.
• Common gotchas:
  • These blades are not mulching or gator blades. They are standard lift blades for side-discharge or bagging.
  • Always replace all three blades at once to maintain balance and cut quality. Mixing old and new blades causes uneven cutting.
  • The 1/4-inch thickness is heavier than many residential blades. Ensure your deck and spindle can handle the weight (most Scag commercial decks can).

Should You Buy It

Buy these if you own a Scag commercial zero-turn with a 61- or 72-inch deck and want factory-matched performance, durability, and zero fitment guesswork. They’re overkill for residential mowers or smaller decks. If you’re on a tight budget or need mulching blades, look at aftermarket options instead.
