942-04290-X 742-04290-X Lawn Mower Blades Gator Mulching Blades for Cub Cadet 46 Inch Deck Replacement for Craftsman Troy Bilt MTD XT1 LT46 LTX 1045 1046 XT2 LX46 ZT1 2Pack

What It Is

This is a 2-pack of aftermarket Gator mulching blades (model 942-04290-X / 742-04290-X) designed for 46-inch cutting decks on select Cub Cadet, Craftsman, Troy-Bilt, and MTD lawn tractors. They’re built to chop clippings finer for better nutrient recycling and a cleaner cut.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measured blade tip to tip). These blades replace OEM part numbers 942-04290 and 742-04290 and fit:

• Cub Cadet: XT1 LT46, LTX 1045, LTX 1046, XT2 LX46, ZT1 (46” deck)
• Craftsman: T110, T150 (46” deck)
• Troy-Bilt: TB46, Bronco 46
• MTD: Yard Machines, Yard Man 46” models Check your blade’s center hole (should be a star/centering hole) and overall length (approx. 20.5 inches). Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Mulching vs. bagging: These are dedicated mulching blades—they create a vacuum to lift grass and cut it multiple times. Not ideal for bagging; swap to standard blades if you bag often.
• Installation torque: Tighten blade bolt to 70-90 ft-lbs. Overtightening can strip the spindle; under-tightening risks blade detachment.
• Sharpening: The serrated edge is difficult to sharpen at home. Replace when dull (usually after 25-30 hours of use).
• Deck leveling: For best mulching, ensure your deck is level side-to-side and front-to-back (1/8” lower in front).

Should You Buy It

If you own a 46-inch Cub Cadet or compatible MTD/Craftsman tractor and want finer clippings without bagging, this is a solid, well-rated upgrade over standard blades. Skip it if you bag frequently or need a universal fit—these are strictly for 46-inch decks with the star-center mount.
