2 Pack 942-04308 High Lift Mower Blades - Replaces 742-04308 942-04308A 942-04312, Fits 42" Deck Troy-Bilt Bronco Pony Mustang, Cub Cadet XT1-42 ZT1-42 Zero Turn with 6 Point Star Center Hole

What It Is

This is a 2-pack of high-lift mower blades designed to replace OEM part numbers 742-04308, 942-04308A, and 942-04312. They fit 42-inch cutting decks on Troy-Bilt Bronco, Pony, and Mustang models, plus Cub Cadet XT1-42 and ZT1-42 zero-turn mowers. The high-lift design increases airflow under the deck for better grass lifting and a cleaner cut, especially in tall or damp grass.

Fitment & Compatibility

Before buying, confirm three things: your deck measures exactly 42 inches (not 46 or 50), your spindle hole is a 6-point star center (common on MTD/Cub Cadet spindles), and your blade length is 20.5 inches end to end. This set is aftermarket, not OEM Cub Cadet, but it matches the original dimensions and mounting pattern. It will not fit decks with a 5-point star or round center hole. If your mower uses a different OEM number (e.g., 942-04310), measure your blade first—length and hole shape must match exactly.

Key Things to Know

• Quality: Made from heat-treated steel; users report they stay sharp longer than OEM blades in light-duty residential use.
• Installation: Requires a socket or wrench for the center bolt—no special tools. Always disconnect the spark plug before working under the deck.
• Common gotcha: High-lift blades create more suction, which can cause clumping in wet grass. Only use them when grass is dry for best results.
• Balance check: After installing, spin the blade by hand to ensure it’s not wobbling. Unbalanced blades cause vibration and bearing wear.

Should You Buy It

Buy this if you have a 42-inch Troy-Bilt or Cub Cadet with a 6-point star spindle and want a budget-friendly upgrade that improves cut quality in normal lawn conditions. Skip it if you mow wet grass often or need OEM parts for warranty compliance.
