What It Is

This is a 46-inch mulching blade set (typically 3 blades) designed for MTD/Cub Cadet lawn tractors. It replaces OEM part numbers 742-04290, 942-04290, 742-04290-X, 942-04290-X, 942-04244, and 742-04244. It’s intended for mulching grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify:

• Deck size: Your mower must have a 46-inch cutting deck. Measure deck width if unsure.
• Model series: Fits Cub Cadet XT1-46, XT2, LT46, LTX1045, LTX1046, and other MTD-built tractors with a 46-inch deck. Cross-check your mower’s model number with the OEM part numbers listed.
• Blade dimensions: Each blade is approximately 15.5 inches long, 2.5 inches wide, with a 5-point star center hole (common for MTD/Cub Cadet). Measure your old blade’s length and center hole shape to confirm.
• OEM vs aftermarket: This is a direct replacement aftermarket blade. It should match OEM specs, but aftermarket blades can vary slightly in thickness or balance. Check that the blade thickness matches your spindle assembly (typically 0.1875 inches).

Key Things to Know

• Installation difficulty: Easy (15-30 minutes). Requires a socket wrench and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• Quality: At $21.99 for a set, these are budget-friendly. The 5.0 rating (3 reviews) suggests good consistency, but low review count means limited long-term feedback.
• Common gotcha: Mulching blades have a higher lift and more curved edge than standard blades. If you switch from bagging/discharge blades, expect finer clippings but potentially more deck buildup in wet grass.
• Balance: Aftermarket blades sometimes need balancing. Use a blade balancer to avoid vibration that can damage the spindle.

Should You Buy It

Buy this if you need an affordable, direct-fit mulching blade set for a Cub Cadet or MTD 46-inch deck tractor and don’t want to pay OEM prices. It’s a solid choice for routine mulching, but if you frequently cut wet or tall grass, consider a gator-style blade for better performance.
