These 3-in-1 blades are designed for mulching, bagging, and side discharge operations. The specific method of operation depends on your mower's configuration and accessories.

- Verpakking: For bagging operations, attach the grass collection bag to your mower. The blades will create airflow to direct clippings into the bag.
- Syafskeiding: If your mower is set up for side discharge, the blades will propel clippings out of the side chute.
Always operate your mower according to its owner's manual. Avoid mowing wet grass, as it can clog the deck and reduce cutting performance.
