6PK Oregon 192-106 Blade for 42" John Deere E120

What It Is

This is a 6-pack of Oregon 192-106 replacement blades designed for 42-inch cutting decks, commonly used on John Deere E120 lawn tractors. They are aftermarket blades intended for mulching, bagging, or side-discharge mowing on residential lawns.

Fitment & Compatibility

• Deck size: Fits 42-inch cutting decks only. Measure your deck width before buying.
• Model fit: Confirmed for John Deere E120, but also compatible with many 42” John Deere LA-series and X300-series mowers. Check your owner’s manual or OEM blade part number (usually AM137254 or AM141254).
• OEM vs aftermarket: Oregon is a reputable aftermarket brand, but these are not John Deere OEM blades. They may differ slightly in thickness or lift profile.
• Measurements: Blade length is 21 inches, center hole diameter is 1 inch, and spindle offset is 1 inch. Verify these match your existing blades.

Key Things to Know

• Quality: Oregon blades are heat-treated and hardened for durability, but may not last as long as OEM on heavy-duty use.
• Installation difficulty: Easy—requires a socket wrench and a blade removal tool. Torque bolts to 70-80 ft-lbs. Always sharpen or replace in sets.
• Common gotcha: The 6-pack is cost-effective, but you only need 3 blades per mower. The extra 3 are spares or for multiple mowers.
• Balance: Always balance new blades after installation to prevent vibration and spindle damage.

Should You Buy It

Buy this if you own a John Deere E120 (or compatible 42” deck model) and want a bulk pack of reliable aftermarket blades at a lower per-blade cost than OEM. It’s a good value for regular residential mowing, but skip if you need exact OEM fit or do heavy commercial cutting.
