Oregon 6PK USA Mower Mulching Blades for Scag 61" 481708 481712 482787 482879 Ferris 5101755

What It Is

This is a set of six mulching blades designed for commercial zero-turn mowers with 61-inch cutting decks, specifically Scag and Ferris models. They replace OEM part numbers 481708, 481712, 482787, 482879, and 5101755, optimized for fine grass clipping shredding to improve lawn health and reduce bagging.

Fitment & Compatibility

• Deck size: Only for 61-inch decks. Measure your deck width before ordering—this set covers the full width, not a single blade.
• Brand/model fit: Scag Turf Tiger, Wildcat, Cheetah, and Patriot (check your model year). Ferris ISX, FW, and FWX series with 61" decks. Not for other brands unless deck pattern matches.
• OEM vs aftermarket: Oregon blades are aftermarket but built to OEM specs. They are a direct replacement for the listed Scag and Ferris part numbers. Verify your existing blade’s center hole size (usually 1" or 1-1/4") and bolt pattern (usually 5-point star or 5/8" hex) to confirm fit.
• Measure before buying: Compare length, thickness, and hole pattern against your current blade. Oregon lists these as 21.5" long, 0.25" thick, with a 1" center hole and 5-point star drive.

Key Things to Know

• Quality: Made in USA from heat-treated steel, reportedly harder than OEM blades, staying sharp longer in heavy use. Expect 2-3 seasons with regular sharpening.
• Installation: Moderate difficulty—requires a torque wrench and blade removal tool. Torque to 70-90 ft-lbs. Use thread locker on bolts to prevent loosening.
• Common gotchas: These are mulching blades (curved, with extra lift fins), not standard or high-lift. They produce finer clippings but may leave clumps in wet grass. Do not use on bagging or side-discharge setups without swapping.
• Noise/vibration: Some users report slightly more vibration than OEM at high RPM; check blade balance before mounting.

Should You Buy It

Buy this if you own a Scag or Ferris 61" zero-turn, want durable mulching blades that outlast OEM, and don’t mind the moderate installation effort. Not ideal if you primarily bag or discharge, or if your deck uses a different bolt pattern—double-check fitment first. The price is competitive for a six-pack of USA-made blades.
