Stihl had them from the 024/034/064084 onwards, husqvarna were later to the inboard clutch party. I don't know firsthand because I've never done any milling but apparently an outboard clutch is preferred by some people for milling , the theory being it transfers some heat out of the crankcase on long sustained cuts at full power. I think theres a bit of wishful thinking there but like I said I've never milled.
