Was doing some research at work today as we're looking at doing a production study on some silvicultural operations. Most of the figures used for productivity etc comes from the NZ Forest Service, which did the work in the 80's and based in on a huge amount of work studies they did. As I was flicking through a folder of costing data I found a page of thinning equipment costings and they gave the lifespan of a saw used for waste thinning as 0.76 years. Saws <69cc were considered suitable for thinning - they listed 041AV, P55, Mac 610 & 650, Husky 162 and Dolmar 122. Guess that explains why those saws are hard to find used here now, they must of had a hard life
