Oregon 3 PK 91-628 Mower Blade Fits Scag A48304 48304 481712 61" Super High Lift

What It Is

This is a set of three Oregon 91-628 Super High Lift mower blades designed for 61-inch Scag commercial zero-turn mowers. They are an aftermarket replacement for OEM Scag part numbers A48304, 48304, and 481712, intended for high-volume grass discharge and improved bagging performance.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 61 inches and uses three blades. These blades fit Scag Turf Tiger, Cheetah, Tiger Cat, and Wildcat models with the 61-inch Velocity Plus or other compatible decks. Check your current blade’s part number against OEM Scag A48304, 48304, or 481712. Measure your existing blade length (should be 20.5 inches), center hole diameter (typically 5/8 inch), and thickness (0.203 inch) to verify fit. These are aftermarket—not OEM Scag—so quality and balance may vary slightly.

Key Things to Know

• Installation difficulty: Easy if you have a torque wrench. Tighten blade bolts to 70-90 ft-lbs. Use a blade removal tool to prevent spinning.
• Lift design: The super high lift profile creates strong airflow for bagging and side discharge but increases engine load and fuel consumption slightly.
• Quality note: Oregon blades are heat-treated and coated for rust resistance, but some users report needing to balance them before first use.
• Common gotcha: These blades are not for mulching—they are designed for discharge and bagging only. Using them on a mulching deck or with a mulch plug will reduce performance.

Should You Buy It

If you own a 61-inch Scag commercial mower and primarily bag or side-discharge grass, this three-pack offers solid value at about $17 per blade. It’s a reliable aftermarket alternative to OEM Scag blades, especially for high-volume cutting. For mulching applications or if you prefer OEM-only parts, look elsewhere.
