6PK Oregon 91-620 Blade for 48" Scag 48110 481706 482877 Lesco 21871 50111 Hustler 601123

What It Is

This is a 6-pack of Oregon 91-620 replacement blades, designed for 48-inch commercial zero-turn mowers—specifically Scag, Lesco, and Hustler models. It’s a drop-in upgrade or replacement for worn OEM blades, ideal for high-use, large-area mowing.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: These blades are for 48-inch decks only. Measure your deck width to confirm.
• Model numbers: Fits Scag (48110, 481706, 482877), Lesco (21871, 50111), and Hustler (601123). Verify your mower’s OEM part numbers against this list.
• Measurements: Blade length is 18.5 inches, center hole diameter is 0.625 inches (5/8 inch), and blade thickness is 0.204 inches. Measure your current blade to match.
• OEM vs aftermarket: Oregon is a reputable aftermarket brand—these are not OEM but are direct replacements. No adapter or modification needed for listed models.

Key Things to Know

• Quality: Oregon blades are heat-treated and hardened for durability. They hold an edge well but may dull faster than premium OEM blades on rocky or sandy terrain.
• Installation: Easy bolt-on job. Use a torque wrench to tighten to 70-85 ft-lbs (check your mower manual). Always replace all three blades at once for balanced cutting.
• Common gotcha: The 91-620 has a specific sail (lift) design. If your mower uses a different lift pattern (e.g., high-lift for bagging), this may not provide the same discharge performance. Check your current blade’s lift design.
• Price vs value: At ~$10 per blade, this is a solid deal for commercial-grade steel. Expect 25-50 hours of cutting life depending on conditions.

Should You Buy It

Buy this if you own a 48-inch Scag, Lesco, or Hustler zero-turn and want reliable, affordable blades for routine replacement. It’s a great value for high-volume mowing, but skip it if you need specialized high-lift blades for bagging or mulching.
