Oregon 3 Pack 92-114 Mower Blade for John Deere TCU15882 72" 7 Iron Deck

What It Is

This is a 3-pack of Oregon 92-114 replacement blades designed for John Deere 72-inch 7 Iron decks. They’re for commercial or large residential mowing where you need sharp, durable blades for thick grass or frequent use.

Fitment & Compatibility

• Deck size: Fits John Deere 72" 7 Iron decks only—verify your deck is exactly 72" and has the 7 Iron stamped on the housing.
• Model numbers: Replaces OEM John Deere part TCU15882. Also compatible with Oregon part 92-114.
• Measurements: Each blade is 22.5 inches long, 2.5 inches wide, with a 0.250-inch thickness and a 7/16-inch center hole. Measure your old blade to confirm these specs—especially length and hole size—since aftermarket blades can vary.
• Aftermarket note: These are Oregon (not John Deere) blades, so they’re a quality aftermarket option but may differ slightly in balance or edge profile. Check that your spindle and blade adapter match the center hole and thickness.

Key Things to Know

• Quality: Oregon blades are heat-treated and sharpened out of the box—good for heavy cutting but may need re-sharpening sooner than OEM in rocky soil.
• Installation difficulty: Moderate—requires removing deck or tilting mower. Torque blade bolts to 70-90 ft-lbs. Use a torque wrench to avoid stripping.
• Common gotcha: The 3-pack is a value buy, but blades are sold as a set—you can’t buy singles. If one blade gets damaged, you’ll need to replace the whole pack.
• Balance check: Always balance after installation—Oregon blades are usually balanced, but shipping can knock them off. Use a blade balancer to avoid vibration.

Should You Buy It

Buy this if you own a John Deere 72" 7 Iron deck and want a reliable, cost-effective aftermarket blade pack for regular mowing. It’s a solid choice for commercial operators or homeowners who mow large acreage and need sharp blades without paying OEM prices. Skip it if you need a single blade or have a different deck size.
