Stihl KM90RStraight Shaft Kombi Trimmer Head Only. Tons of Kombi shaft attachments are available, I am selling the power head only. The machine runs great and has no issues. I ONLY run NON Ethanol fuel with Stihl 501 mix and Stabil. I am selling because I inherited a larger Kombi and therefore I am selling this power head. This has been homeowner owned and used, NO commercial or professional use.
