Overview

Upgrade your mowing routine with the DOCAS 21-Inch Mulching Blades. This 2-pack is designed to fit a wide range of 21-inch deck mowers, including popular models from MTD, Cub Cadet, Troy-Bilt, and Craftsman. Replacing worn blades with this set can help maintain a steady cutting rhythm and a tidy lawn without needing a separate bagging system.

Broad compatibility for many 21-inch decks

The blades are crafted to replace OEM numbers such as 742-04100, 742-0741, 742-0741A, 942-0741, and 942-0741A. They also fit Craftsman CMXGZAM100067 and a variety of White Outdoor, Cub Cadet, and Troy-Bilt 21-inch mowers, making it easier to stock a single spare blade for multiple machines.

Mulching action for a neat finish

These 21-inch mulching blades deliver a finer cut of grass clippings, helping them break down more quickly and distribute across the lawn. The result can look cleaner from pass to pass, with less visible debris and faster turf recovery after mowing.

• Fine-cut clippings promote quicker nutrient return to the soil
• Even distribution supports a consistent lawn appearance

Exact fit and practical installation

Each blade measures 21 inches in length and 2-1/5 inches in width with a bow-tie center hole design that aligns with standard mounting hardware. The 2-pack provides a ready replacement option for two sides of the deck, making swaps straightforward.

• Bow-tie center hole aids stable, secure mounting
• Two blades per pack for quick deck refresh

Real-world use and care tips

When mowing tall or damp grass, mulching blades can help maintain a steady cutting rhythm and reduce clumping over multiple passes. For best results, inspect blades for wear and keep the mower deck clean to support consistent performance over time.

Maintenance note: Regularly check blade balance and torque during installation to ensure safe operation and optimal mowing results.
