UDC Parts 942-0616A Mower Blades Replacement for Cub Cadet 42 Inch XT1 LT42 with 6 Star Hole Craftsman T110 Troy Bilt Pony RZT42 T210 LT4200 742-0616A 942-0616 Zero Turn / 2 Pack Gator Mulching

What It Is

This is a 2-pack of aftermarket mulching blades designed for 42-inch cutting decks on popular lawn tractors and zero-turn mowers. The “Gator” style features a serrated edge and angled wings to recirculate clippings for finer mulching, making them ideal for frequent mowing without bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and uses blades with a 6-star center hole (also called a 6-point star drive). These blades replace OEM numbers 742-0616A and 942-0616A. They fit models including:

• Cub Cadet: XT1 LT42, LT42, RZT42
• Craftsman: T110, T210, LT4200
• Troy-Bilt: Pony, Bronco, RZT42

Measure your existing blade length—these are 20.5 inches long, 1.75 inches wide, and 0.25 inches thick. Not compatible with 46-inch or 54-inch decks, or blades with a round center hole or different star pattern.

Key Things to Know

• Mulching performance: The serrated edge and wings produce finer clippings than standard blades, but they work best when mowing dry grass no more than 1/3 of the blade height at a time.
• Installation difficulty: Easy—removes with a single bolt per blade. Use a torque wrench to tighten to 50-70 ft-lbs. Left-hand threads are common on some models (check your deck).
• Quality vs OEM: These are stamped steel, not hardened like some OEM blades. They may dull faster in sandy or rocky soil but are a solid value for typical suburban lawns.
• Balance: Out of the box, these are generally well-balanced, but it’s smart to check on a balancer before installing to avoid vibration.

Should You Buy It

If you own a 42-inch Cub Cadet, Craftsman, or Troy-Bilt tractor and want an affordable upgrade over standard blades for better mulching without buying OEM, this 2-pack delivers. It’s not for heavy-duty commercial use or extremely tall grass, but for regular residential mowing, it’s a proven, high-rated choice.
