UDC Parts 942-04290 Mower Blades Replacement for 46 Inch Cub Cadet XT1 LT46 6 Point Star 942-04290A LTX 1045 1046 XT2 LX46 742-04290-X 942-04244A Craftsman / 2 Pack Mulching Gator

What It Is

This is a 2-pack of mulching Gator blades designed for 46-inch decks on Cub Cadet XT1, XT2, and LTX series tractors, as well as select Craftsman models. They use a 6-point star center hole and are meant to replace OEM part numbers 942-04290, 942-04290A, 742-04290-X, and 942-04244A.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 46 inches from blade tip to blade tip. These fit Cub Cadet XT1 LT46, LTX 1045, LTX 1046, XT2 LX46, and Craftsman models with the same 6-point star mounting pattern. Check your current blade’s OEM number—if it matches any listed above, you’re good. Measure blade length: it should be about 20.5 inches. The 6-point star is not universal; some older or non-Cub decks use a 5-point or keyed hole. Also verify spindle orientation—these are for side-discharge decks, not rear-discharge.

Key Things to Know

• Mulching vs. bagging: These Gator blades have a serrated edge and curved wingtips designed to chop clippings finer for mulching. They’re less effective for bagging or side-discharge.
• Installation difficulty: Moderate—you’ll need a socket wrench, torque wrench (set to 70-90 ft-lbs), and a blade removal tool or block of wood to lock the blade. Always disconnect the spark plug first.
• Common gotcha: The 6-point star hole can be tight on some spindles. If it doesn’t slide on easily, lightly file the star points—don’t force it.
• Balance: These are pre-balanced from the factory, but always check balance after sharpening or if you hit debris.

Should You Buy It

If you have a 46-inch Cub Cadet XT1, XT2, or LTX series deck and primarily mulch your grass, this is a solid upgrade over standard blades. The price is fair for a 2-pack, and the high rating reflects good durability. Skip it if you need blades for bagging or side-discharge—these are optimized for mulching only.
