2 PCS 942-04308 High Lift Lawn Mower Blades - Fit for Troy Bilt Bronco Pony Mustang Lawn Mower Cub Cadet 42'' Deck Riding Mower RZT42 - Replace 942-04308A 942-04308-X 942-04312 742-04312

What It Is

This set of two high-lift lawn mower blades is designed for 42-inch cutting decks on popular Troy-Bilt, Cub Cadet, and MTD riding mowers. The high-lift design increases airflow under the deck to improve grass clipping discharge and bagging performance, making it ideal for tall or thick grass.

Fitment & Compatibility

Before buying, confirm three things: your deck size (must be exactly 42 inches), blade length (check your current blade—typically 20.5 inches center to tip), and the center hole shape (most use a 5-point star or oval hole). This blade replaces OEM numbers 942-04308, 942-04308A, 942-04308-X, 942-04312, and 742-04312. It fits Troy-Bilt Bronco, Pony, Mustang, and Cub Cadet RZT42 models with a 42-inch fabricated or stamped deck. If your mower uses a different blade pattern (e.g., 3-point star or round hole), this will not work.

Key Things to Know

• Installation difficulty: Easy to moderate—requires a socket wrench and a block of wood to jam the blade. No special tools needed.
• Quality: Made from heat-treated steel; reviewers note they stay sharp through a full season of regular mowing.
• Common gotcha: High-lift blades create more lift, which can strain the engine on very thick grass. Mow at a slower ground speed to avoid bogging.
• Balance check: Always balance new blades before mounting—unbalanced blades cause vibration and damage spindle bearings.

Should You Buy It

If you have a 42-inch deck Troy-Bilt or Cub Cadet riding mower and want better bagging or discharge in tall grass, these are a solid upgrade. They’re priced competitively, fit multiple common OEM numbers, and most users report easy installation and good durability. Avoid if you have a different deck size or a mower with a non-standard blade mount.
