742-0616A Mower Blades for Cub-Cadet 42 Inch Mower, 942-04308 Mulching Blades for Craftsman/Troy Bilt/MTD 42" Riding Lawn Mower, Replace for 942-0616, 942-0616-X, 942-04126-X, 4 Pack

What It Is

This is a 4-pack of mulching blades (model 742-0616A) designed for 42-inch riding mower decks. They replace OEM part numbers 942-0616, 942-0616-X, and 942-04126-X, and are compatible with Cub Cadet, Craftsman, Troy-Bilt, and MTD models that use a three-blade 42-inch cutting deck.

Fitment & Compatibility

Before buying, measure your deck width—must be exactly 42 inches. Verify your current blade part number matches one of the listed OEM replacements (942-0616, 942-0616-X, or 942-04126-X). These are aftermarket blades, not OEM, but direct-fit for most MTD-built 42-inch riding mowers, including Cub Cadet XT1, LTX 1042, and Craftsman T110/T120. Check blade length (typically 15.5 inches), center hole diameter (usually 1-inch), and thickness (0.25 inches). Confirm your spindle pattern—these are for three-blade decks only, not two-blade or four-blade setups.

Key Things to Know

• Quality: Steel construction, but aftermarket—may not hold an edge as long as OEM. Expect adequate mulching for residential use, not heavy commercial.
• Installation: Straightforward if you have a blade removal tool and torque wrench. Tighten to 70–90 ft-lbs. Mark blade orientation before removal to ensure correct reinstallation.
• Common gotcha: Mulching blades have a curved, wing-like design—they won’t bag or discharge as well as standard blades. Use only for mulching or side-discharge, not bagging.
• Pack size: Four blades included—enough for one full deck replacement with one spare.

Should You Buy It

If you own a 42-inch MTD/Cub Cadet/Craftsman riding mower and want an affordable mulching blade set for regular residential lawn care, this is a solid value. Not ideal for heavy-duty or commercial use, but fine for standard mulching needs at half the cost of OEM.
