Oregon 6 Pack 92-114 Mower Blade for John Deere TCU15882 72" 7 Iron Deck

What It Is

This is a 6-pack of Oregon 92-114 replacement blades designed for John Deere 72-inch 7 Iron decks (model TCU15882). It’s for commercial or heavy residential mowing on zero-turn and riding mowers with that specific deck.

Fitment & Compatibility

• Primary fit: John Deere 72" 7 Iron deck (OEM part #TCU15882). Not for standard 60" or 48" decks.
• Measure first: Blade length must be 22.5 inches (center hole to tip). Center hole diameter is 3/4 inch. Verify your blade’s length and hole size before buying.
• Aftermarket: This is an Oregon (aftermarket) blade, not OEM John Deere. It’s a direct replacement but may differ slightly in thickness or steel composition. Check that your spindle accepts 3/4" hole blades.
• Deck compatibility: Only for the 7 Iron deck (deep-deck design). Will not fit standard flat decks or older 72" models without the 7 Iron designation.

Key Things to Know

• Quality: Oregon is a respected aftermarket brand. These are heat-treated, hardened steel with a balanced design. Expect similar durability to OEM at a lower per-blade cost.
• Installation: Straightforward if you have a torque wrench (recommended torque: 70-90 ft-lbs). Use anti-seize on the spindle bolt to prevent seizing. No special tools beyond a socket and breaker bar.
• Gotcha: The 6-pack is a good value if you mow large areas or replace blades frequently. But if you only need 3 blades (typical for a 3-spindle deck), you’ll have 3 spares.
• Sharpness: These come unsharpened (dull edge). You’ll need to sharpen them before first use or have a sharpening service do it.

Should You Buy It

Yes, if you own a John Deere with a 72" 7 Iron deck and mow regularly. The 6-pack is cost-effective for commercial use or anyone who hates frequent trips to the store. Skip it if you prefer OEM parts or only need a single set—buy a 3-pack instead.
