942-04308-X 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 42'' Deck Lawn Tractor Zero-Turn Mower, Black

What It Is

A set of three 42-inch, 6-star mulching blades designed for 42-inch cutting decks on Cub Cadet XT1, XT2, LT42, LX42, ZT1, RZT, and LTX 1040 models, plus Craftsman T110/T210 and Troy-Bilt TB 42/TB1942 tractors and zero-turns. These blades replace OEM part numbers 942-04308-X and 942-0616A, intended for fine grass clipping mulching rather than side discharge or bagging.

Fitment & Compatibility

• Deck size must be exactly 42 inches – measure deck width (cutting swath) before ordering.
• Check your model’s OEM part number – these replace 942-04308-X and 942-0616A. Verify your current blade’s stamped number matches one of these.
• Fitment list includes Cub Cadet XT1/XT2/LT42/LX42/ZT1/RZT 42/LTX 1040, Craftsman T110/T210, Troy-Bilt TB 42/TB1942. Not compatible with 46-inch or larger decks.
• Aftermarket set – not genuine Cub Cadet, but designed to same specs. Confirm blade length (42-inch deck blades are typically 20.5 inches center-to-center) and center hole size (usually 1-inch or 7/8-inch – measure yours).
• Check blade thickness and lift – aftermarket blades may have slightly different lift height; test on a small patch first to avoid scalping.

Key Things to Know

• Quality: 4.6/5 rating from 65 reviews – generally positive, but a few report balance issues. Inspect each blade for straightness before installing.
• Installation difficulty: Moderate. Requires a socket wrench, torque wrench (set to 70-90 ft-lbs), and jack stands to lift the mower safely. Always disconnect the spark plug.
• Common gotchas: Aftermarket blades may not have the same hardened steel as OEM – expect slightly shorter lifespan if mowing rocky or sandy lawns. Ensure the 6-star pattern matches your deck’s spindle design (some older decks use 5-star).
• Mulching only: These are not designed for bagging or side discharge. If you switch between modes, keep your original blades.

Should You Buy It

Best for owners of 42-inch Cub Cadet, Craftsman, or Troy-Bilt tractors/zero-turns who want a budget-friendly mulching upgrade and don’t need OEM brand. Avoid if you require maximum durability for heavy-duty commercial use or if your deck uses a different blade pattern.
