Oregon 6PK 94-063 Replacement Blades for 50" Toro 112-9759, 115-5059, 110-6837

What It Is

This is a set of six aftermarket replacement blades for 50-inch Toro commercial zero-turn mowers (models with deck part numbers 112-9759, 115-5059, or 110-6837). Designed for high-use commercial mowing, these blades are made by Oregon (not EGO—the brand listed is likely a marketplace error).

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 50 inches. These blades won’t fit 48", 52", or 60" decks.
• OEM cross-reference: Direct replacement for Toro part numbers 112-9759, 115-5059, and 110-6837. If your mower uses any of those OEM blade part numbers, these fit.
• Measurements: Each blade is 18.5 inches long, 2.5 inches wide, with a 7/16" center hole and 1/4" offset. Measure your current blade to confirm—aftermarket blades can vary slightly in thickness or hole size.
• Common compatible mowers: Toro Groundsmaster 4000, 4100, 4500, and certain Z-Master commercial models. Check your mower’s deck manual or look up the OEM part number on the existing blade.

Key Things to Know

• Quality vs OEM: Oregon is a reputable aftermarket brand. These blades are heat-treated and balanced, but some users report slightly shorter life than OEM Toro blades on heavy commercial use.
• Installation difficulty: Easy. Remove the center bolt, swap blades, and torque to 70-80 ft-lbs. No special tools needed beyond a wrench or impact gun.
• Common gotcha: These blades are sold as a set of six—verify your deck uses six blades (most 50" Toro decks do, but some older models use four). Also, check that your deck has the correct spindle spacing; these are not universal.
• Sharpening: They can be sharpened, but Oregon blades tend to have a thinner edge that may wear faster after sharpening.

Should You Buy It

Buy these if you need a budget-friendly, reliable replacement for a 50-inch Toro commercial mower and you’re comfortable with aftermarket quality. They’re a good value for light-to-medium commercial use or residential mowing. For heavy daily commercial use, consider sticking with OEM Toro blades for longer life.
