942-04290-X 942-04290 942-04244 742-04244 742-04290 Mulching Blades - Fits 46 inch Mower Deck Cub Cadet RZT-L46 RZT-S46 XT1-LT46 XT2-LX46 ZT1-46 LTX1045 LTX1046 (2Pack)

What It Is

This is a 2-pack of mulching blades (part #942-04290, 942-04244, 742-04244, 742-04290) designed for 46-inch cutting decks on Cub Cadet RZT, XT, and ZT series lawn tractors. They chop clippings finer than standard blades for better nutrient recycling.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 46 inches (measured blade tip to tip). These will not fit 42- or 54-inch decks.
• Model series: Fits Cub Cadet RZT-L46, RZT-S46, XT1-LT46, XT2-LX46, ZT1-46, LTX1045, and LTX1046. Also fits some Craftsman and MTD models with the same deck, but confirm by checking your current blade part number.
• Measurements: OEM blades are 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.25-inch thickness. Measure your old blade—if these match, they’ll work.
• OEM vs aftermarket: These are OEM replacement blades from Cub Cadet, not generic aftermarket. They match factory specs.

Key Things to Know

• Installation difficulty: Easy (30 minutes with a socket wrench). Use a blade removal tool or block the blade to prevent spinning. Always disconnect the spark plug first.
• Mulching vs bagging: These will leave more clippings on the lawn than standard blades. If you bag frequently, consider a dedicated bagging blade instead.
• Sharpness out of box: They come sharp but not razor-edged. Expect a break-in period of 1-2 mows for optimal mulching performance.
• Common gotcha: The 2-pack is for single-blade decks. If your 46-inch deck uses two blades (most Cub Cadet 46" decks do), you’ll need two packs (4 blades total). Check your deck’s blade count before ordering.

Should You Buy It

Buy these if you own a Cub Cadet 46-inch deck tractor (RZT, XT, or ZT series) and want OEM-quality mulching blades that fit without modification. They’re ideal for homeowners who mulch regularly and want finer clippings without switching to aftermarket parts. Skip them if you need bagging blades or if your deck uses a different blade length/center hole size.
