3PK Oregon 91-620 Blade for 48" Scag 48110 481706 482877 Lesco 21871 50111 Hustler 601123

What It Is

This is a 3-pack of Oregon 91-620 replacement blades designed for commercial 48-inch zero-turn mowers, specifically fitting Scag, Lesco, and Hustler models. They are aftermarket blades intended to match OEM part numbers for durability and cutting performance.

Fitment & Compatibility

• Deck size: Only for 48-inch decks (3 blades required per set).
• OEM cross-references: Scag 48110, 481706, 482877; Lesco 21871, 50111; Hustler 601123.
• Measurements: Each blade is 16.5 inches long, 2.5 inches wide, with a 5-point star center hole (1-inch diameter) and 0.25-inch thickness.
• Check before buying: Measure your current blade length and center hole shape. The star pattern is specific—round or oval holes won’t fit. Verify your deck is 48" and uses three blades (not two or four). Confirm your mower brand and model from the list above; if it’s not listed, measure and compare.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. These are heat-treated steel with a balanced design, typically as good as OEM for residential or light commercial use.
• Installation: Straightforward—remove old blades, reinstall with the lift wings pointing up toward the deck. Torque to 70-90 ft-lbs. Use a blade removal tool to avoid spinning.
• Common gotcha: The star center hole can be tight on some spindles. Lightly file if needed, but don’t force it. Also, these blades are not “mulching” or “gator” style—they are standard lift blades for side-discharge or bagging.
• Pack includes: Three blades, but no hardware (bolts, washers). Reuse your old hardware or buy new if worn.

Should You Buy It

If you own a 48" Scag, Lesco, or Hustler zero-turn and need a reliable, cost-effective set of standard lift blades, this 3-pack is a solid choice. It’s cheaper than OEM and performs well for regular mowing. Not ideal if you need mulching blades or have a different deck size/center hole pattern.
