Parts Camp 2-Pack 942-04308 742-04308-X 942-0616 742-0616 Toothed Mulching Mower Blades 21-1/4" for 42" Deck, Fits Cub Cadet XT1-LT42 XT2-LX42, for MTD & Craftsman Riding Mowers with 42 Inch Deck

What It Is

This is a 2-pack of 21-1/4-inch toothed mulching blades designed for 42-inch decks on select Cub Cadet, MTD, and Craftsman riding mowers. The aggressive serrated edge chops clippings finer for better nutrient recycling, ideal for mulching without bagging.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Must be exactly 42 inches – measure your deck’s cutting width, not the blade length.
• Blade dimensions: Each blade is 21-1/4 inches long with a 1-inch center hole and 7-point star pattern. Measure your existing blade’s length, center hole, and drive pattern.
• Model fit: Listed for Cub Cadet XT1-LT42 and XT2-LX42, plus many MTD and Craftsman 42-inch deck riders. Cross-reference your mower’s model number with OEM part numbers 942-04308, 742-04308-X, 942-0616, or 742-0616. Not universal – check your manual or current blade part number.

Key Things to Know

• Quality: Aftermarket blades made from heat-treated steel. Hardness and edge retention may be slightly less than OEM Cub Cadet blades, but adequate for typical residential use.
• Installation: Straight swap – use a torque wrench to 45-55 ft-lbs. Note that the toothed edge can be sharper than standard blades; handle with gloves.
• Common gotcha: The 7-point star drive pattern fits most, but some older MTD decks use a 5-point star. Verify your spindle’s drive pattern before buying.
• Mulching vs. side-discharge: These are strictly for mulching. If you often bag or side-discharge, consider a 3-in-1 blade set instead.

Should You Buy It

If you own a Cub Cadet XT1-LT42 or XT2-LX42 (or a compatible MTD/Craftsman 42-inch deck rider) and want a budget-friendly mulching blade upgrade for finer clippings, this 2-pack is a solid value. Skip it if you need OEM-grade hardness for heavy commercial use, or if your deck uses a 5-point star drive.
