Compatibility and Inclusions
The KB-MM is a MultiSystem bristle-brush attachment for the STIHL MM 56 MultiEngine. It is not the KB-KM KombiTool. This listing includes the bristle-brush attachment and guard extension, not an engine or complete powered sweeper.
Need a power unit? The STIHL MM 56 petrol tiller kit includes BF-MM pick tines and a wheel kit. The KB-MM brush is a separate optional attachment. Fit the approved guard assembly and all components specified in both manuals; the tiller kit alone does not supply every guard needed for brushing.
Handling Accessories
A compatible STIHL MultiSystem wheel kit can help with lifting and manoeuvring on uneven ground. It is an optional accessory, not included with this brush attachment. Browse KombiSystem and MultiSystem accessories and confirm the exact fitting requirements for your machine.

Safe Use and Care
