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 (model 942-0616A) designed to fit riding lawn mowers and zero-turn mowers with a 42-inch cutting deck. They are intended for fine mulching—chopping clippings into small bits to return nutrients to the lawn—rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and uses three blades (most 42" decks do). This set is a direct fit for Cub Cadet XT1, XT2, LT42, LX42, ZT1, RZT 42, and LTX 1040 models, as well as Craftsman T110/T210 and Troy-Bilt TB 42, TB1942, Super Bronco, and Pony with a 42" deck. It is an aftermarket replacement for OEM part 942-0616A. Measure your existing blade’s length (center hole to tip) —it should be about 21 inches (42-inch deck uses ~21" blades). Also check the center hole diameter (usually 1" or 3/4") and the blade thickness (typically 0.25"). If your mower uses a different spindle pattern or offset, this set won’t fit.

Key Things to Know

• Mulching only: These blades have a high-lift, curved design for mulching. They will not work well for bagging or side discharge—expect clumping if used in wet grass.
• Installation difficulty: Easy swap—requires a socket wrench and a blade removal tool or block of wood to hold the blade. Torque to 70-80 ft-lbs (check your manual).
• Quality: Made of heat-treated steel with a black coating for rust resistance. Reviews note they stay sharp for 10-15 hours of mowing, but sharpen more often in sandy soil.
• Common gotcha: The 6-star pattern refers to the mulching serrations, not the center hole shape. Ensure your deck’s spindle bolts match the blade’s center hole (usually a 5/8" hex or round hole with a star pattern).

Should You Buy It

Buy these if you own a compatible Cub Cadet, Craftsman, or Troy-Bilt 42-inch deck mower and want to mulch grass clippings into fine, natural fertilizer. They’re a solid aftermarket value at $23.88, but skip them if you bag or side-discharge often—stick with standard lift blades for those tasks.
