Stihl KombiSystem & Attachments KM130R KM131R 10 Year Australia Used Review Kombi System KM 131 R

I purchased my first Stihl KombiSystem - KM130R “KombiEngine” - approximately 10 years ago.I was looking at a new edger and brushcutter for my home property and orchard respectively. I decided to combine the two into one product and see how that went.Over 10 years later, this is how I have felt about that decision. How has the Stihl KombiSystem performed over a long period of time. What are the advantages of the system and what are the disadvantages?
