Oregon 6 Pack 91-628 Super High Lift Blade Fits Scag A48304 48304 481712 61"

What It Is

The Oregon 6 Pack 91-628 is a set of six super high-lift mulching blades designed for 61-inch Scag commercial zero-turn mowers. They’re built for heavy-duty grass cutting, leaf shredding, and bagging, with aggressive airlift that pulls clippings up into the deck for a finer cut and better dispersal.

Fitment & Compatibility

• Deck size: 61 inches (6-blade spindle setup). Not for 52-inch or 72-inch decks.
• Brand/model: Fits Scag models using OEM part numbers A48304, 48304, or 481712. Common on Scag Turf Tiger, Wildcat, and Cheetah with 61-inch decks (check your machine’s parts diagram).
• OEM vs aftermarket: Direct replacement for Scag OEM blades. No adapter or modification needed if your deck uses these part numbers.
• Measurements: Blade length is 20.5 inches, center hole diameter 1 inch, with a 0.5-inch offset. Confirm your spindle’s bolt pattern matches (5-point star or 5-hole) – these use a standard 5-point star.
• What to check before buying: Verify your Scag deck is 61 inches and uses 6 blades. Look up your mower’s serial number or existing blade part number to match A48304/48304/481712. Measure blade length and hole size if unsure.

Key Things to Know

• Quality: Oregon is a top aftermarket brand – blades are heat-treated for durability and balanced out of the box. Expect 40–60 hours of life on commercial use, less if you hit debris.
• Installation: Moderate difficulty. You’ll need a 1-inch socket and torque wrench (tighten to 70–90 ft-lbs). A blade removal tool or impact wrench helps. Lift deck safely – use a jack or blocks.
• Gotchas: Super high-lift blades create more vacuum, which can strain the deck belt if it’s worn or loose. Check belt condition before installing. They’re noisier than standard blades due to increased airflow. Not for wet grass – clogs easily.
• Common issue: Some users report slight imbalance if the blades are stored in the pack; spin-test each blade on a balancer before installing. Replace all six at once for even wear.

Should You Buy It

Buy if you own a 61-inch Scag commercial mower with a 6-blade deck and want OEM-grade cutting performance with superior bagging or mulching. The price is competitive with OEM Scag blades, and the 4.9-star rating reflects consistent quality. Skip if your deck uses different blade patterns, you need standard (non-high-lift) blades for dry conditions, or you’re on a tight budget – this is a premium set for serious users.
