Allett Aggressive Scarifier Cassette

The "Dethatcher" is the "most aggressive" cultivation cartridge with curved blades in wider areas. High-speed blades rotate to cut and remove lawn thatch, pruning plants and their roots. This cartridge should only be used in spring and autumn when there is moisture in the lawn. After using this cartridge, it is recommended to apply fertilizer for the lawn to recover. The "Dethatcher" cartridge removes twice as much material from the lawn as the "Verticut" cartridge.

The cartridge can be used in February, March, and September, October.
