What It Is

This is a set of three high-lift blades designed to replace OEM part numbers 942-04308, 942-04308A, 742-04308, 742-04312, and 942-04312. They’re intended for 42-inch cutting decks on Troy-Bilt Pony, Bronco, Mustang, Cub Cadet XT1, and RZT42 zero-turn mowers. High-lift blades create stronger airflow to improve grass discharge and bagging performance.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck—these blades will not fit smaller or larger decks. Check your current blade’s OEM part number; this set directly replaces the 942-04308 series. Measure your blade’s length (should be about 20.5 inches), center hole diameter (typically 1 inch), and the distance between mounting holes (usually 3.75 inches). Verify your deck spindle pattern matches—most Troy-Bilt and Cub Cadet models use a three-hole mounting pattern. Aftermarket blades may have slight weight or thickness differences from OEM, but they should bolt on without modification.

Key Things to Know

• Installation difficulty: Easy—remove the old blade, clean the spindle, and bolt on the new one. Use a torque wrench to tighten to 40-50 ft-lbs.
• Material: Made from hardened steel, but not as thick as premium OEM blades. Expect slightly shorter lifespan if you hit rocks or roots.
• Balance: Each blade should be balanced before installation. An unbalanced blade will vibrate, damage the spindle, and cut unevenly.
• Gotcha: High-lift blades increase deck clogging in wet, thick grass. They’re best for dry conditions and bagging—switch to standard or mulching blades for damp grass.

Should You Buy It

Buy these if you have a compatible 42-inch Troy-Bilt or Cub Cadet mower and need a budget-friendly replacement for bagging or dry-weather discharge cutting. Avoid them if you frequently mow wet grass, hit debris, or prefer OEM durability—consider a thicker OEM blade set instead.
