Aerodynamics and mulching performance

Designed with curved geometry, the blades create strong airflow as they cut, propelling clippings in a continuous cutting cycle and turning them into finely chopped material. This design can support more efficient bagging and reduce the risk of blade clogging, especially during tougher cuts. Expect the possibility of up to 50% more bagging capacity as the clippings are processed more consistently.

• 6-point star center hole pattern: length 21-3/16" (538 mm), width 2-3/8" (60 mm), thickness 0.16" (4.0 mm); compatible with 42" decks
• MULCHING blade type crafted to finely chop clippings and return nutrients to the lawn
• High-strength steel with advanced heat treatment for improved hardness and durability
• Protective paint coating during production offers extra corrosion protection and helps protect hands during installation

Durability and testing you can rely on

Each blade undergoes a rigorous suite of tests, including dynamic balance checks, Rockwell hardness, V-bend evaluations, blade chip tests, performance trials, and field tests. The result is a blade designed to handle demanding mowing tasks and uneven terrain while delivering consistent results.

• Coated surfaces wear over time, reducing direct friction during use and installation
• Engineered for long-term performance with reliable cutting and steady grass return

Fit guidance and care

Before purchase, please confirm that your center hole pattern matches the 6-point star configuration and that the mower model corresponds to a 42" deck. These blades are listed as replacements for OEM parts and are designed to fit a range of Cub Cadet, Troy-Bilt, Craftsman, and similar models when the pattern aligns.

Note: Always inspect the compatibility details and installation requirements prior to switching blades to ensure optimal results and safe operation.
