What It Is

The GICOOL 942-0616A is a set of three mulching blades designed for 42-inch cutting decks on select Cub Cadet, MTD, and Troy-Bilt lawn tractors. These blades chop grass clippings finely and recirculate them into the lawn for natural fertilization, ideal for frequent mowing.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and uses blades with a 6-star center hole (3.78-inch diameter, 0.5-inch center pilot). These replace OEM part numbers 942-04308, 742-0616A, 742-0616, 942-0616, and 742-04126. They fit many Cub Cadet, MTD, and Troy-Bilt Bronco models (e.g., 13A-325, 13A-329, 13W-276). Check your owner’s manual or measure your old blade’s length (20 inches) and hole pattern. Aftermarket, so not identical to OEM—verify deck clearance and spindle bolt size (typically 5/16-24 or 3/8-24; use your original bolts).

Key Things to Know

• Quality: Made of heat-treated steel with a painted finish; reviews note they’re slightly thinner than OEM but durable for residential use.
• Installation: Easy with basic tools (socket wrench, torque to 70-90 ft-lbs). Ensure blades are installed with the cutting edge facing upward (mulching) and rotate freely.
• Gotchas: The 6-star hole is specific—won’t fit oval or 5-point hole patterns. Check for deck interference if your mower has a wash port or discharge chute.
• Performance: Works best with dry, short grass; may clog in wet or tall conditions compared to OEM high-lift blades.

Should You Buy It

Buy these if you need a budget-friendly, direct-fit mulching replacement for a 42-inch Cub Cadet, MTD, or Troy-Bilt tractor and mow frequently enough to avoid heavy clumping. Skip them if you have a different deck size, a non-star hole pattern, or prefer OEM thickness for heavy-duty use.
