Boasting wider spaced, thicker tines the Dethatcher is the most aggressive cartridge and penetrates the soil to a maximum depth of 6mm.

For lawns in serious disarray, the Dethatcher removes the densest layers of thatch effectively.

The machine works by rigorously penetrating the soil’s surface in order to pick up and remove layers of thatch such as dead grass and leaves, plant stolons and weed growth. Lawns grow healthier, thicker and more luscious once this has been removed as it's less susceptible to disease. Lawns that are more susceptible to disease encourage moss growth which should be avoided.

Removal of excessive thatch and moss enables more water, air and nutrients to absorb into the soil to be provided to the grass root, and should be carried out at least once a year in late Spring or Autumn only when moisture is available for the lawn to recover. The dethatcher cartridge removes twice as much material as the Verticut cartridge.
