Oregon 42 Inch Lawn Mower Blades, Gator G3 Blades for 42" Deck, 21-3/16" Length, Replacement for Cub Cadet 942-04308-X, MTD 942-04308-X, Troy Bilt 942-04308-X and Fits Cub Cadet, MTD and more (2 Pack)

What It Is

The Oregon 42 Inch Gator G3 Blades are a high-lift, mulching-style replacement blade set designed for 42-inch residential riding mower decks. They upgrade cutting performance with aggressive wing geometry for finer clippings and better bagging.

Fitment & Compatibility

• Deck size: 42 inches; measure your deck width and blade length (21-3/16 inches) before purchase.
• Direct OEM replacements: Cub Cadet 942-04308-X, MTD 942-04308-X, Troy Bilt 942-04308-X.
• Fits many: Cub Cadet, MTD, Troy Bilt, Craftsman, Yard Machines, and other MTD-built 42-inch decks with a 5-point star center hole.
• Critical check: Measure the center hole shape (star vs. oval) and blade length. If your mower uses a different hole pattern or shorter blade, these won’t fit.

Key Things to Know

• Quality: Oregon is a top aftermarket brand; G3 blades are heat-treated and coated for durability, comparable to OEM.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Torque center bolt to 70–90 ft-lbs. Sharp edges—wear gloves.
• Common gotcha: G3 blades are more aggressive than standard blades; they may slightly increase engine load and vibration if deck is bent or unbalanced.
• Pack includes: Two blades (for 42-inch decks typically using two blades). Verify your deck uses a pair, not three.

Should You Buy It

If you want a noticeable upgrade in mulching and bagging quality over standard OEM blades for your Cub Cadet, MTD, or Troy Bilt 42-inch deck, these are a solid, affordable choice. Avoid them if your mower uses a different center hole pattern or blade length.
