I'm 58 years old and I'm in decent but not excellent physical condition. Average strength I would say.
I am not a chainsaw guy. In other words, I've been using decent consumer Stihl chainsaws all my life but I don't know anything about cc's, chain types, tuning, modding etc etc. Primary use has been yard and property cleanup as well as cutting firewood. I have the proper safety gear and a solid understanding of basic chainsaw safety.
But now I have ordered a saw mill. It should be here in a few weeks. It can handle up to 26" diameter trees.
My primary saw is a Stihl Farm Boss with a 20" bar. I don't remember which one but it is about 3 years old, bought new and was the larger of the Farm Boss saws. In my mind I'm thinking 350 but it might be a 271. I don't even know if the Farm Boss came in a 350. Anyway, it is a decent saw. I suspect it is a consumer level saw with a "farm" designation for marketing.
This weekend I felled several pines that were around 12 inches in diameter. The Farm Boss was okay but not great. I also recently cut up a much larger oak blow down (probably 25ish diameter) and the Farm Boss struggled a lot.
So I am going to be felling larger trees than 12" pines in the near future. My son-in-law will be there most of the time (we'll own the saw mill together). He has a big tuned pro-level Stihl. He has a good bit of felling experience. But I feel like I need a bigger saw for myself. I'm thinking 25-28" bar.
I'm not really looking for brand recommendations.
What I need to know is what I can get for this job that is: 1) Reasonably light. (Again, I'm 58). 2) Appropriately powered for cutting down large but not huge trees. 3) Reasonably safe for my age and experience and 4) What type of chain for my age and experience from a safety vs efficiency standpoint.
Any basic advice much appreciated.
P.S.: Not too interested in modding or tuning a saw.
