The 165 mm wide scarifying roller fits all MultiBrush devices and is ideal for treating lawn areas in spring and autumn in the home garden. Eight stainless steel knife discs effectively and easily remove dead plant debris from the lawn, which would otherwise hinder grass growth. By working the green area with the scarifying roller, the nutrient absorption of the soil is optimized. The grass grows denser and becomes more resilient. The package includes a filter that can be attached to the air intake of the devices to protect the engine compartment from clogging with grass clippings. Of course, this attachment is also compatible with older MultiBrush models.
