What It Is

This is a 2-pack of toothed mulching blades designed for 46-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors. They are meant to replace OEM blades when you want finer grass clippings for mulching rather than bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measured blade tip to tip). These blades fit models like Cub Cadet XT1-46, XT2, LT46, LTX1045, and LTX1046, plus many MTD and Troy-Bilt tractors with a 46-inch deck. They replace OEM part numbers 942-04290, 942-04290-X, 742-04244, 942-04244, and 742-04290. Measure your blade length (should be ~20.5 inches), center hole size (typically 1 inch), and spindle shape to verify match. Check your deck’s blade offset and thickness—these are usually 0.25-inch thick with a 0.5-inch lift. Not for 42-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket blades, generally sturdy but may not hold an edge as long as OEM. The toothed design improves mulching but can dull faster on sandy or rocky soil.
• Installation: Easy with a socket wrench and blade removal tool. Always disconnect the spark plug and secure the blade with a block of wood. Torque to 70-90 ft-lbs.
• Gotchas: The toothed edge can leave a rougher cut if your deck isn’t level or blades are unbalanced. Check balance before installing—unbalanced blades cause vibration and poor cut. These are not for bagging or discharge; they’re strictly mulching.
• Pack: Two blades for $27.99 is a solid value compared to single OEM blades at $25+ each.

Should You Buy It

Buy these if you have a compatible 46-inch MTD/Cub Cadet tractor, primarily mow on clean grass (no debris), and want a budget-friendly mulching upgrade for finer clippings. Skip them if you need OEM durability for rough terrain, or if you often bag or side-discharge—these are optimized for mulching only.
