What It Is

These are mulching blades for 42-inch cutting decks on Cub Cadet, MTD, Troy-Bilt, and select other lawn tractors. They chop clippings finer than standard blades to reduce bagging needs and return nutrients to the lawn.

Fitment & Compatibility

Deck size: Only fits 42-inch decks. Measure your deck width before buying.
Blade type: 6-point star center hole (not oval or universal). OEM part 942-0616A replaces 742-0616A, 742-0616, and 942-0616.
Models: Compatible with Cub Cadet XT1, XT2, RZT Zero Turn, and Troy-Bilt Bronco, Pony, and MTD-branded 42-inch decks.
Check: Verify your deck’s spindle star pattern matches this 6-point design. Measure blade length (22 inches) and center hole diameter (1 inch) against your old blade.

Key Things to Know

• Quality: OEM-grade steel with heat-treated edge. Holds sharpness longer than cheap aftermarket blades.
• Installation: Easy DIY swap—remove one bolt per blade, re-torque to 70-80 ft-lbs. Use a blade lock tool or wood block to hold the blade.
• Gotchas: Mulching blades work best with a mulching plug installed and dry grass. Wet or tall grass may clog.
• Balance: New blades are pre-balanced, but always check balance after sharpening.

Should You Buy It

Yes—if you own a Cub Cadet, MTD, or Troy-Bilt 42-inch deck with a 6-point star spindle and want better mulching performance. Good value at $24 for a two-pack. Avoid if you need standard bagging or side-discharge-only blades.
