12PK 61" Oregon Lawn Mower Blades 91-626 Replacement for Ferris 1520842 1520842S 5101755, Scag 48111 481708 481712 482879 48304, Wright Stander 50170 71440003

What It Is

This is a 12-pack of 61-inch Oregon Gator G5 mulching blades (part 91-626) designed for zero-turn mowers with high-output decks. It replaces OEM blades for Ferris, Scag, and Wright Stander models, ideal for commercial operators needing frequent blade swaps.

Fitment & Compatibility

• Deck size: Fits 61-inch cutting decks only. Measure your deck width before buying.
• Brand models: Direct replacement for Ferris (1520842, 1520842S, 5101755), Scag (48111, 481708, 481712, 482879, 48304), Wright Stander (50170, 71440003). Check your mower’s model number against these.
• OEM vs aftermarket: Oregon is a trusted aftermarket brand. These blades match OEM dimensions (3/8" center hole, 0.25" thickness, 1.0" width) but have a different cutting edge profile. Confirm your deck uses a standard 5-point star spindle pattern.
• Measurements: Blade length is 20.5 inches (3 blades per set). Verify your spindle bolt pattern (typically 5-hole, 4.0" bolt circle). If your deck uses a different pattern, these won’t fit.

Key Things to Know

• Quality: Oregon G5 blades are heat-treated steel with a hardened edge for longer life compared to many OEM blades. They mulch well but may produce slightly less lift than OEM high-lift blades.
• Installation: Moderate difficulty—requires a torque wrench (spindle bolts to 70-90 ft-lbs) and a blade removal tool. Use anti-seize on bolts to prevent seizing.
• Gotchas: The 12-pack is cost-effective for high-use mowers, but check your blade wear rate. If you mow light grass, you might overbuy. Also, these are not universal—double-check your deck’s blade pattern (some Wright or Scag decks use different bolt patterns).
• Warranty: Oregon offers a limited lifetime warranty against defects, but not wear and tear.

Should You Buy It

If you run a Ferris, Scag, or Wright Stander with a 61-inch deck and need a bulk supply of reliable mulching blades for commercial use, this is a solid buy. The per-blade cost is low, and Oregon’s reputation is strong. Skip it if your deck uses a non-standard spindle pattern or you prefer high-lift blades for bagging.
