I am looking at purchasing the Stihl Kombi System, it is a powerhead (31.4cc. 1.3bhp) with a split shaft PTO with interchangeable attachments. The attachments I am looking at are the Power Scythe, Pole Pruner and Trimmer. The total cost for the power head and 3 attachments is @ $760. Anyone have any experience with the Stihl Kombi System??? What do you think?
