942-0616A 942-04308-X 42 inch Mulching Blades for Cub Cadet XT1-42 ZT1-42 LT42 RZT42 Craftsman T110 Troy Bilt Bronco Pony 42" Zero Turn Riding Mower Replaces 742-0616A 742-0616 942-0616, 2 Pack

What It Is

This is a 2-pack of 42-inch mulching blades designed for residential riding mowers. They replace OEM part numbers 742-0616A, 742-0616, and 942-0616, and are intended for machines with a 42-inch cutting deck that use a three-blade spindle system.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and uses three blades. These blades are commonly compatible with:

• Cub Cadet XT1-42, ZT1-42, LT42, RZT42
• Craftsman T110, T120, T130 (42-inch decks)
• Troy-Bilt Bronco, Pony (42-inch models)
• Many Husqvarna, Poulan Pro, and MTD 42-inch zero-turn riders that use the same blade pattern.

Critical checks:

• Blade length: 18.5 inches (center hole to tip).
• Center hole: 5-point star (common for MTD-style spindles).
• Thickness: 0.25 inches.
• OEM cross-reference: Verify your current blade has the same center hole shape and length. If your mower uses a different spindle design (e.g., round hole or longer blades), these will not fit.

Key Things to Know

• Quality: These are aftermarket blades, not OEM Cub Cadet. They are made from heat-treated steel and should handle residential use well, but may not last as long as genuine parts in heavy or rocky conditions.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (recommended 40-55 ft-lbs), and a blade removal tool or wooden block to prevent spinning. Always disconnect the spark plug first.
• Mulching vs. bagging: These blades have a curved, high-lift design for fine clippings. They will not perform well for bagging or side discharge – stick to mulching only.
• Common gotcha: The 5-point star center hole can be tight on some spindles. If it doesn’t seat fully, don’t force it; file the hole slightly or return the blades.

Should You Buy It

If you own a common 42-inch MTD-platform riding mower (Cub Cadet, Craftsman, Troy-Bilt) and primarily mulch leaves or grass, this is a cost-effective 2-pack. Skip them if you need bagging performance, have a different deck size, or require OEM-grade durability for commercial use.
