Upgrade your mower with the BCQNXX 742P05642 Mulching Blade

Designed for Cub Cadet, MTD, and Troy-Bilt 21-inch deck walk-behind mowers, this blade replaces the parts 742-05642 and 742P05642 and ships as a single unit. It fits 21-inch decks with a 2-inch blade width and features a diamond center hole for secure mounting.

Why this blade stands out

  • Durable steel construction stands up to regular mowing, helping blades stay sharp through many passes.
  • The powder-coated finish resists dust and rust, supporting a clean, consistent cut over time.

In real-world use, you’ll notice smoother mowing as the blade slices grass evenly and reduces streaking. Mulching action reintroduces fine clippings into the turf, which can contribute to a tidy lawn and healthier soil under favorable conditions.

Compatibility and fit

  • Fits Cub Cadet SCP21E walk-behind mowers and 21-inch deck configurations.
  • 2-inch blade width and diamond center hole ensure stable mounting and reliable performance.

Installation is straightforward with common tools. You will need a wrench and should take a few careful steps: disconnect the spark plug, lift the deck to the highest position, remove the old blade, replace it with the new one, and reassemble and test the mower. Regular blade checks help maintain a clean cut lawn.

Key specs at a glance

  • Length: 21 inches
  • Width: 2 inches
  • Center hole: diamond
  • Package: 1 mulching blade
  • Deck compatibility: 21-inch walk-behind mowers

Bottom line: BCQNXX offers a reliable replacement option for a familiar mowing routine. While results can vary with grass type and conditions, a sharp, well-mounted blade can contribute to a more even and efficient cut while maintaining equipment longevity.
