942-04308 Mower Blades Fit for 42 Inch Deck, 742-04308A High Lift Blades Compatible with Troy Bilt Pony, Cub-Cad et XT1-LT42 XT2-LX42, Replace 942-0616A, 742-04312, 2 Pack

What It Is

This is a 2-pack of 42-inch deck high-lift mower blades designed to replace OEM parts on select Troy-Bilt, Cub Cadet, and similar lawn tractors. High-lift blades create stronger airflow for improved grass clipping discharge and bagging performance.

Fitment & Compatibility

Before buying, verify your deck measures exactly 42 inches (cutting width). These blades are direct replacements for OEM numbers 942-0616A and 742-04312. They fit several models including: Troy-Bilt Pony, Cub Cadet XT1-LT42, XT2-LX42, and others using the 742-04308A pattern. Measure your existing blade’s center hole diameter (typically 7/8-inch) and overall length. Confirm the blade mounting pattern (usually 5-point star or oval hole) matches your spindle. Check your owner’s manual for deck model number to avoid returns.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench, jack stands or ramps, and safety glasses. Torque blade bolts to 70-90 ft-lbs (check manual).
• Quality note: Aftermarket blades may be slightly lighter or thinner than OEM. They sharpen well but may wear faster on rocky or sandy lawns.
• Common gotcha: High-lift blades increase engine load and may cause clumping in wet grass. Use only on dry grass for best results.
• Balance check: Always balance new blades before mounting – use a blade balancer or nail in a wall. Unbalanced blades cause vibration and spindle wear.

Should You Buy It

If you own a compatible 42-inch Troy-Bilt or Cub Cadet tractor and want better bagging or discharge than standard blades, this is a solid budget-friendly pick. It’s not ideal for mulching (low-lift blades work better) or for heavy commercial use where OEM durability is preferred. For light to medium residential mowing, it delivers good value.
