942-04308 Lift Mower Blades Replace for 942-04308A Compatible Troy Bilt Bronco Pony 42''Mower,Cub Cadet XT1 LT42 42 inch Deck Lawn Mower

What It Is

This is a set of three 42-inch replacement blades designed for lifting and cutting grass on Troy-Bilt Bronco/Pony and Cub Cadet XT1 LT42 lawn tractors with a 42-inch deck. It’s an aftermarket alternative to OEM part 942-04308A.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches (measured blade tip to tip). This set fits Troy-Bilt Bronco, Pony, and Cub Cadet XT1 LT42 models that use OEM part 942-04308 or 942-04308A. Also compatible with some MTD and Craftsman tractors with a 42-inch deck and the same spindle pattern. Measure blade length (should be ~20.5 inches), center hole diameter (typically 1 inch), and thickness (0.25 inch). Check your deck’s blade alignment – some aftermarket blades require centering washers or spacers not included.

Key Things to Know

• Quality: Made from heat-treated steel, but may be slightly thinner or lighter than OEM. Expect similar cutting performance but potentially shorter life on rough terrain.
• Installation: Easy swap if you have a socket wrench and blade removal tool. Torque bolts to 70–90 ft-lbs. Always disconnect spark plug first.
• Common gotchas: Blades may need balancing before install – use a blade balancer. If your deck uses a “double” blade configuration (stacked), these won’t fit. Check that your spindle has the correct 5-point star pattern.
• Noise/vibration: Some users report slight vibration at high RPMs if blades aren’t perfectly balanced. Re-check after first mow.

Should You Buy It

Buy this set if you need a budget-friendly, direct replacement for worn OEM blades on a standard 42-inch Troy-Bilt or Cub Cadet tractor and are comfortable doing a simple swap with basic tools. Avoid if you require OEM-grade durability, have a non-standard deck, or want blades pre-balanced out of the box.
