6PK Oregon 91-626 Blade for 61" Scag 48111 481708 Ferris 5020842 5101755 Simplicity 5022808ASM

What It Is

This is a set of three 61-inch replacement blades for commercial zero-turn mowers, designed for high-volume cutting on large lawns, sports fields, or commercial properties. The Oregon 91-626 is a direct aftermarket alternative to OEM blades for Scag, Ferris, and Simplicity decks.

Fitment & Compatibility

Before buying, verify these four things:

• Deck size: This blade set is specifically for 61-inch cutting decks. Do not use on smaller or larger decks.
• Brand/model: Fits Scag (part #48111, 481708), Ferris (part #5020842, 5101755), and Simplicity (part #5022808ASM). Check your mower’s deck model number, not just the engine brand.
• OEM cross-reference: The Oregon 91-626 replaces OEM blades listed above. If your mower uses a different OEM part number, measure the blade length, center hole diameter (usually 5/8” or 1/2”), and thickness before ordering.
• Measurements: Each blade is 20.5” long, 2.5” wide, with a 5/8” center hole. Verify these against your current blade.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. These blades are hardened steel with a balanced design, but may wear slightly faster than OEM on abrasive turf or rocky soil.
• Installation: Moderate difficulty—requires a torque wrench (set to 70-90 ft-lbs) and a blade removal tool. Always replace all three blades at once for balanced cutting.
• Common gotchas: The blades are not universal for all 61” decks—some Ferris models use a different blade pattern. Also, check that your mower’s blade spindle matches the 5/8” center hole; some older decks use a 1/2” hole.
• Performance: Expect a clean, even cut on grass up to 6” tall. Not ideal for mulching or bagging—these are lift blades for side-discharge use.

Should You Buy It

Buy this if you have a 61” Scag, Ferris, or Simplicity zero-turn and want a reliable, budget-friendly alternative to OEM blades. It’s a solid choice for commercial or large residential use, provided you confirm fitment and don’t need specialized mulching blades. Skip it if your deck uses an uncommon spindle size or you prefer OEM for maximum longevity.
