942-0616A 42 inch 6-Star Mulching Blades for Cub Cadet XT1 XT2 LT42 LX42 ZT1 RZT 42 LTX 1040 Craftsman T110 T210 Troy Bilt TB 42 TB1942 Super Bronco Pony 42'' Deck Lawn Tractor Zero-Turn Mower, Black

What It Is

This is a set of three 42-inch 6-star mulching blades designed for select Cub Cadet, Craftsman, and Troy-Bilt lawn tractors and zero-turn mowers with a 42-inch deck. They’re built for frequent mulching, chopping clippings fine enough to leave on the lawn.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck—these blades won’t fit 46-inch or larger decks. Check your model number against the list: Cub Cadet XT1, XT2, LT42, LX42, ZT1, RZT 42, LTX 1040; Craftsman T110, T210; Troy-Bilt TB 42, TB1942, Super Bronco, Pony. Measure your existing blade length (42 inches is the overall width of the deck, not the blade itself—each blade is typically about 20.5 inches long). This is an aftermarket part, not OEM Cub Cadet, but it’s designed as a direct replacement. Verify the center hole diameter (usually 7/8-inch) and the number of holes (often 3 or 5) match your spindle.

Key Things to Know

• Installation is straightforward—just remove the old blades with a socket wrench, but always disconnect the spark plug and block the deck first.
• Mulching performance depends on mowing frequency; these blades work best if you cut no more than 1/3 of the grass height at a time.
• Check blade thickness—these are typically 0.17-inch thick, which is standard for residential use; thinner blades may bend on rocks or roots.
• Balance is critical—after installing, test blade balance on a nail or balancer; an unbalanced blade causes vibration and uneven cut.

Should You Buy It

If you own a compatible 42-inch deck tractor or zero-turn from Cub Cadet, Craftsman, or Troy-Bilt and want a cost-effective mulching upgrade over standard lift blades, this set is a solid choice. It’s not for heavy-duty commercial use, but for regular residential lawn care at $25, it delivers good value and fine mulching action.
