How exactly do you burn up that many saws? Do you sharpen the chains, or just run them until something breaks?
I honestly don't get that.
But then, I don't get why people say the things they do about a MS-150, either. I just took two mulberry trees down with one. Didn't switch to a bigger saw until there was only four feet of the main trunks standing there. They weren't huge trees, about 16" dbh and 14" dbh and both were about 25' tall. But, really, you should just cut a tree down with one. If you think it will take longer, or be too much for the saw, or that it won't cut fast enough... you're going to be in for a big surprise.
If you break saws that fast, you might seriously think about switching to the Echo saws. You'd at least cut your saw expenses in half. Better yet, stop breaking saws. I have a pile of tophandle saws (no Huskies, though) and I've never broken any of them. Trashed a few chains, wore out a bar or two. I even have one from the '70s that is still running. Push button oiler, and all. The things last forever, if you treat 'em nice.
