42" Mower Blades Set for Cub Cadet MTD Craftsman XT1-LT42 XT2-LX42 Z5200 Lawn Mower Replaces OEM 742P05177-L 490-110-C198 CMXGZAM110199 2 Pack

What It Is

This is a 2-pack of 42-inch mower blades designed for residential riding mowers and zero-turn mowers with 42-inch cutting decks. They replace OEM part numbers 742P05177-L, 490-110-C198, and CMXGZAM110199, and are intended for mulching, bagging, or side-discharge cutting.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck (measure deck width if unsure). These blades fit specific Cub Cadet, MTD, and Craftsman models, including XT1-LT42, XT2-LX42, and Z5200. They also fit many MTD-built tractors with 42-inch decks. Check your current blade’s length, width, center hole diameter (usually 1-inch or 7/8-inch), and offset. Measure your blade’s length from tip to tip—it must be exactly 21 inches per blade to total 42 inches. Verify your mower uses a 2-blade system (not 3). Cross-reference your OEM part number against the listed replacements.

Key Things to Buy

• Quality: Aftermarket blades; may not be as thick or durable as OEM. Some users report faster dulling than factory blades.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Torque blade bolts to 70-90 ft-lbs. Use thread locker if recommended.
• Gotcha: Blade orientation matters—the lift wing must face upward toward the deck. Installing backward causes poor cutting and vibration.
• Balance: Check blade balance after sharpening. Unbalanced blades can damage the spindle and deck.

Should You Buy It

Buy this set if you need affordable replacement blades for a 42-inch Cub Cadet, MTD, or Craftsman riding mower and you’re comfortable with basic installation. They work well for routine mulching and bagging but may dull faster than OEM blades if you cut dense or tall grass frequently. For heavy-duty use or commercial mowing, consider premium OEM blades.
