742-04308 Mower Blades Fit for Cub-Cad et Troy Bilt 42" Deck, 942-04308A Blades for Cub Cad et XT1-LT42 XT2-LX42 Riding Mower, Craftsman LT1500 42" Lawn Tractor, 2 Pack

What It Is

This is a 2-pack of 42-inch replacement mower blades designed for a range of Cub Cadet, Troy-Bilt, and Craftsman riding mowers. They’re for standard cutting and mulching on residential lawns, not for heavy-duty commercial use.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Must be exactly 42 inches. Measure your mower deck if unsure—these blades won’t fit 46” or 54” decks.
• Model fit: Directly replaces OEM part numbers 742-04308 and 942-04308A. Fits Cub Cadet XT1-LT42, XT2-LX42, Troy-Bilt 42” deck models, and Craftsman LT1500. Not universal—check your owner’s manual for those OEM numbers.
• Measurements: Blade length is 21.5 inches (center hole to tip), center hole is 1 inch, and the drive pin holes are 0.5 inch. Measure your old blade to confirm these match.
• Aftermarket note: These are aftermarket (not genuine Cub Cadet/Craftsman), but they match OEM specs. If you need exact factory balance or coating, buy OEM.

Key Things to Know

• Quality: Good for the price—medium-carbon steel, sharp out of the box. Won’t last as long as premium heat-treated blades, but fine for 1-2 seasons of residential mowing.
• Installation: Straightforward—remove the old blade, note the washer/bolt order, and torque to 70-90 ft-lbs. Use a blade removal tool or block the blade with wood.
• Common gotcha: These are not “universal.” If your mower uses a different center hole size (e.g., 7/8” or 1-1/8”), they won’t fit.
• Balance: Check each blade for balance before installing (hang on a nail through the center hole). Unbalanced blades cause vibration and bearing wear.

Should You Buy It

Buy these if you own a Cub Cadet, Troy-Bilt, or Craftsman 42” riding mower with OEM part 742-04308 or 942-04308A and want a solid, affordable replacement for regular residential cutting. Skip them if you need longer-lasting premium steel, a different blade style (mulching vs. bagging), or if your deck has a different center hole size.
