LawnRAZOR Blade for Cub Cadet MTD Craftsman XT1-LT42E ZT1-42E Z5200 42-Inch Deck 742P05720 742-05720 Mulching 2 Pack

What It Is

The LawnRAZOR Blade for Cub Cadet MTD Craftsman XT1-LT42E ZT1-42E Z5200 42-Inch Deck is a mulching blade set (2-pack, OEM part 742P05720 / 742-05720) designed for 42-inch cutting decks on select Cub Cadet, MTD, and Craftsman lawn tractors and zero-turn mowers.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Must be a 42-inch deck. Measure your deck width if unsure.
• Model compatibility: Fits Cub Cadet XT1-LT42E, ZT1-42E, Z5200, and many MTD/Craftsman models with the same 42-inch deck. Check your mower’s model number against 742P05720.
• OEM vs aftermarket: This is an OEM-style replacement from Cub Cadet, not a universal blade. It matches the exact mounting pattern, center hole (typically 7/8-inch), and offset of the original.
• Measurement: Blade length is approximately 21 inches (total width). Verify your old blade matches this length.

Key Things to Know

• Mulching performance: The blade design lifts clippings for finer cut and better dispersal. Not ideal for bagging or side-discharge use—dedicated blades exist for those.
• Installation difficulty: Easy for DIYers. Use a socket wrench (typically 9/16-inch or 5/8-inch bolt). Torque bolts to 70–90 ft-lbs. Always lift the deck or remove the blade with the spark plug disconnected.
• Common gotcha: The 3.8-star rating (26 reviews) may reflect occasional reports of shorter-than-expected blade life on heavy-duty or rocky lawns. Inspect regularly for bending or dulling.
• Packaging: 2-pack means you replace both blades at once—good practice for balanced cutting.

Should You Buy It

Buy this if you own a 42-inch Cub Cadet, MTD, or Craftsman mower covered by the fitment list and want a direct OEM mulching blade replacement with no guesswork. Skip it if you need a universal blade, bagging blade, or if your deck size differs—or if you’re on very rough terrain and want a thicker, heavy-duty aftermarket option.
