• The individual blade measures 18.5 inches long and 3 inches wide.

• Features a 6-point star center mounting pattern.

• This is a 2-in-1 side-discharge and bagging blade, not a dedicated mulching blade.

• Confirm compatibility using your mower model number, cutting deck configuration, and illustrated parts diagram.

• Not every MTD, Cub Cadet, Troy-Bilt, or Craftsman mower uses the same cutting blade.

• Inspect the blade spindle, mounting hardware, and cutting deck for wear or damage before installation.

• Replace bent, cracked, or excessively worn blades to maintain proper cutting performance.

• Follow the mower manufacturer's blade installation, tightening torque, and safety instructions.
