942-0616A Mulching Blades for 42" Deck, 742-0616A Blades Compatible with Craftsman Troy-Bilt MTD Riding Lawn Mower, Replaces 942-04308 742-04308 942-0616 942-0616-X 942-04126-X, 2 Pack

What It Is

This 2-pack of mulching blades (model 942-0616A) is designed for 42-inch cutting decks on select Craftsman, Troy-Bilt, and MTD riding lawn mowers. The blades chop grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck—measure if unsure. These blades replace OEM part numbers 942-04308, 742-04308, 942-0616, 942-0616-X, and 942-04126-X. They are aftermarket, not genuine MTD/Craftsman parts. Check the center hole diameter (commonly 1-inch or 7/8-inch) and overall length (typically 21 inches) against your current blade. Verify your spindle pattern—most 42-inch decks use a 5-point star or oval hole. Cross-reference your mower model with the seller’s fitment list to avoid returns.

Key Things to Know

• Quality: Made from hardened steel, but some users report slightly thinner material than OEM blades. Inspect for balance before mounting.
• Installation: Requires a socket wrench and torque to 70-90 ft-lbs. Lift the deck safely and block it before working. Sharp edges—wear gloves.
• Common gotcha: Mulching blades need sharpening more often than standard blades, especially in thick or wet grass. Dull blades tear grass, leading to browning.
• Pack includes: Two blades only; no washers or hardware. Reuse your existing center bolt and lock washer if in good condition.

Should You Buy It

Best for budget-conscious owners of 42-inch Craftsman, Troy-Bilt, or MTD riders who want a clean, bag-free lawn and don’t mind replacing blades more frequently than premium OEM sets. Avoid if you need exact OEM fit or plan to cut tough, overgrown grass regularly.
