What It Is

This is a set of two mulching blades designed for 42-inch riding mower decks, intended to replace OEM blades on Troy Bilt Bronco/Pony/Mustang and Cub Cadet models. They chop grass clippings into fine particles for nutrient recycling, ideal for frequent mowing without bagging.

Fitment & Compatibility

• Deck size: 42 inches only—measure your deck width before buying.
• Star hole: 6-point star center hole (common for MTD/Cub Cadet spindles).
• OEM replacements: Fits 942-04308A, 942-04308-X, 942-04312, 742-04312.
• Brands: Troy Bilt Bronco, Pony, Mustang; Cub Cadet LT/LTX/XT1/XT2 with 42" fabricated deck; also MTD, Yard Machines, Craftsman (check your spindle pattern).
• Check: Measure blade length (likely ~20.5 inches), hole size (center star), and deck offset. If your deck is stamped steel vs. fabricated, confirm blade thickness matches.

Key Things to Know

• Mulching vs. high-lift: These are mulching blades—curved to recut clippings, not for bagging or side discharge. Use with a mulching plug/cover.
• Installation: Easy if you have a socket wrench and blade removal tool. Torque to 40-50 ft-lbs. Mark blade orientation before removing old ones.
• Sharpness: Decently sharp out of box, but may need re-sharpening after 5-10 hours on rough terrain. Replace if bent or nicked.
• Durability: Heat-treated steel, but avoid hitting rocks or roots—can warp.

Should You Buy It

If you own a 42-inch Troy Bilt or Cub Cadet rider and want a budget-friendly mulching upgrade for clean, fine clippings, this is a solid pick. It’s not for bagging or rough debris, but for regular mowing on well-maintained lawns, it’s reliable and fits most common MTD-style spindles.
