Nature rarely picks up after itself, but you can restore your lawn's health with the STIHL RL-MM Dethatcher Attachment. Engineered for the STIHL YARD BOSS® yard care system, this powerful tool acts like a vacuum cleaner for your grass, grabbing dead thatch, moss, and accumulated organic materials directly from the top of the soil. By removing this suffocating layer, you allow essential sunlight, water, and nutrients to reach the roots of your turf.
The RL-MM features a series of high-tension spring tines that comb through the grass without damaging the healthy root system. Regular dethatching is a critical step in professional lawn maintenance, preventing the buildup that leads to disease and shallow root growth. As a genuine YARD BOSS® accessory, it slides onto the MultiEngine drive shaft for quick, tool-free transitions between your tilling and lawn care tasks.
Required Safety Configuration: To ensure proper debris management and operator safety, this attachment must be used with the STIHL Large Deflector and Extensions (sold separately). Never operate the Dethatcher without the correct protective guarding in place.
