As already stated by a few knowledgeable members, chainsaw popularity depended upon the strength of the local saw dealerships. In rural areas like ours, saws, parts and repair personnel were very limited. My timeline started around 1958 with Pioneers, they were the only chainsaws sold locally at that time. To get another brand we had to drive 45 miles and at that time it was not feasible to be travelling that far very often. My grandfather owned IEL`s, dad bought his first Pioneer 600 in 1968, we ran Pioneer til the mid 80`s around that time the dealer changed over to Poulan and we bought 306A`s . Ran them for a while til the mufflers rusted out, no replacement parts were available, dealer went out of business, no internet. Then we found Sachs Dolmar and bought 116 and 120 Supers, they were great saws and we had a great dealer but eventually Makita bought them out and the dealer lost all support from Makita, he closed shop. Makita were absolutely impossible to deal with, still leaves a very bad taste in my mouth. Around 1990 we went with Stihl using the 044`s and stayed with them til this day. My time in the woods cutting commercially is about over but I still recommend to the younger cutters to stay with either Stihl or Husqvarna due to the continuing support from the manufacturers. All other brands are just too hit or miss on their dependability of servicing and whether they will be there after sales.
