Scag 3PK Genuine OEM Marbain 72" STHM SW SWZ Deck Cutter Mower Blades 482882

What It Is

This is a set of three genuine Scag OEM Marbain mower blades (part #482882) designed for 72-inch Scag decks on STHM, SW, and SWZ models. They are high-lift, airfoil-style blades built for heavy-duty commercial cutting and superior grass discharge.

Fitment & Compatibility

Before buying, verify your deck size is exactly 72 inches and your Scag model is one of these: STHM, SW, or SWZ series. This is a genuine OEM part, so it matches factory specs—no fitment guesswork. Check your current blade part number (should be 482882 or cross-reference) and measure blade length (should be ~24.75 inches with a 1-inch center hole and 3/8-inch thickness). For non-Scag decks or smaller mowers, this will not fit.

Key Things to Know

• Quality: Marbain steel is heat-treated and hardened for longer edge life compared to standard carbon steel—expect up to 50% more cuts before sharpening.
• Installation: Straightforward bolt-on replacement on a Scag spindle deck; requires a torque wrench (recommended 70-80 ft-lbs) and proper blade orientation (lift side up). No special tools beyond a socket set.
• Gotchas: These are high-lift blades—great for bagging or side-discharge, but they can create more dust and wear in dry conditions. Not ideal for mulching unless you swap to a mulching kit.
• Set includes: Three blades (one per spindle), so no need to buy extras for a 3-blade deck.

Should You Buy It

If you own a 72-inch Scag STHM, SW, or SWZ and want factory-grade durability with minimal downtime, this is the right choice. It’s a premium OEM part that outlasts most aftermarket options, but it’s only worth it if your deck matches exactly. For non-Scag machines or smaller decks, skip this.
