Precise fit and mounting
This blade uses a circle mounting pattern with a centered hole to ensure balanced operation.

Before purchasing, confirm your center hole pattern to avoid installation issues.

- Deck compatibility: 21-inch; circle mounting pattern; center hole geometry
Aerodynamic performance for efficient mowing
The blade features curved surfaces designed to generate strong airflow during cutting. This airflow helps grass move through the cutting cycle, producing finely chopped clippings that can be returned to the soil as a nutrient. The design can also contribute to an increased bagging capacity, reducing the frequency of stoppages when collecting clippings.
- Robust airflow maintains cutting momentum
- Finely chopped clippings aid soil nutrient recycling
- Potential for higher bagging capacity with fewer clogs
Durability you can rely on
Made from high-strength steel with advanced heat treatment, the blade is built to withstand tough mowing, weeds, and uneven terrain. The finished cut remains neat and even, mirroring the precision of a quality handheld scissor cut through challenging patches.
- High-strength steel with heat treatment for hardness
- Durable against weeds and uneven terrain
- Neat, even cut across varied conditions
Quality testing and protection
Chway subjects the blade to a rigorous test regime, including dynamic balance, Rockwell hardness, V-bend, chip, performance, and field tests. A protective paint coating adds corrosion resistance and helps guard hands during installation, supporting long-term reliability and user safety.
- Dynamic balance and hardness tests for reliability
- V-bend and chip tests validate toughness
- Paint coating provides corrosion protection and safer handling
Real-world use and expectations
This mulching blade aims to deliver crisp, consistent cuts while recycling clippings into the lawn. It is designed to be a practical upgrade for gardeners seeking efficiency and a tidy finish, especially on 21-inch Husqvarna and Craftsman decks. Results vary with mower setup and maintenance, but many users notice smoother operation and easier upkeep when using a compatible mulching blade.
Note: Verify center hole pattern before purchase to ensure installation goes smoothly.
