What It Is

This is a 2-pack of 42-inch mulching blades designed for select Cub Cadet, Craftsman, MTD, and Troy-Bilt lawn tractors with a 42-inch cutting deck. They replace OEM part numbers 742-0616A, 742-0616, and 942-0616, and are intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch deck—measure the cutting width if unsure. These blades fit popular models including Cub Cadet XT1, XT2, LT42, LX42, RZT42, Bronco, and Pony, plus Craftsman LT42 and Troy-Bilt TB42. Check your owner’s manual for OEM part number 742-0616A, 742-0616, or 942-0616. Measure your existing blade length (center hole to tip) to confirm 42-inch deck size. These are aftermarket replacements, not OEM Cub Cadet parts, so quality and balance may vary. Ensure your deck spindle bolts match the blade center hole size (typically 5/8-inch on these models).

Key Things to Know

• Quality: 4.9 rating from 23 reviews suggests consistent sharpness and balance, but aftermarket blades can be thinner or less durable than OEM. Inspect for burrs or uneven edges before installation.
• Installation: Easy with basic tools—use a socket wrench and block the blade to prevent rotation. Torque spindle bolts to 45-55 ft-lbs. Always disconnect the spark plug first.
• Common gotchas: Mulching blades have a curved design that may not fit standard discharge or bagging decks without a mulch plug kit. Replace blades in pairs to keep deck balanced.
• Warranty: Using aftermarket blades may void mower warranty if damage occurs—check your mower’s terms.

Should You Buy It

If you need affordable replacement mulching blades for a 42-inch deck tractor and have verified compatibility with your model (Cub Cadet, Craftsman, MTD, or Troy-Bilt), this 2-pack offers good value at $22.88 with strong user feedback. It’s best for routine mulching and light-duty use—if you mow thick, wet grass frequently, consider OEM blades for longer life.
