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

What It Is

This is a set of six aftermarket mulching/standard blades for 61-inch zero-turn mowers, designed as a direct replacement for high-end commercial decks like Scag, Ferris, and Simplicity. The Oregon 91-626 blades are built for heavy-duty cutting and mulching on large residential or commercial properties.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 61 inches wide—this set covers the full width. Check your OEM blade part numbers against the listed cross-references: Scag 48111 and 481708, Ferris 5020842 and 5101755, Simplicity 5022808ASM. Also verify blade length (approximately 20.5 inches), center hole diameter (typically 1 inch), and thickness (0.204 inch). Measure your current blades if possible—Oregon blades are aftermarket, so slight dimensional variances can occur. Not compatible with 60-inch or 72-inch decks.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand; these blades are heat-treated and hardened for durability, but may not last as long as OEM on heavy commercial use.
• Installation: Straightforward bolt-on replacement—no modifications needed if fitment matches. Use a torque wrench to tighten to manufacturer specs (usually 70-90 ft-lbs).
• Balance: Check blade balance after installation; Oregon blades are precision-ground but occasional imbalances occur. Use a balancer to avoid vibration.
• Mulching vs. Bagger: These are standard blades—not dedicated mulching or high-lift bagger blades. For fine mulching, consider Oregon’s G5 or G6 series.

Should You Buy It

If you own a 61-inch Scag, Ferris, or Simplicity zero-turn and want a cost-effective, solid-performing blade set for routine mowing, this is a reliable choice. It’s best for homeowners or light commercial users who don’t require OEM longevity or specialized lift for bagging. For heavy commercial use or specific mulching needs, stick with OEM or dedicated Oregon G-series blades.
