haha, experienced... good question... Ive just managed not to die as of yet. Rough business felling trees, I haver very much respect for guys that do it professionally.
For anyone contemplating chainsaws Id give some advice I wish I received. I have used homeowner/ranch saws for 10 years now. No problems, really good experience with Stihl and those models. That said buying a pro model a few years back (T handle Stihl 201) is a game changer for fine work. I recently bought a Stihl MS261... good saw so far. If I could do it over for bucking I do go bigger- MS362 would be a stellar option and a better option for felling larger trees. Its nice to have tool for fine and gross work. Frankly speaking the saw type isn't the focus, I'm just relaying I wish I had purchased one slightly bigger saw for bucking, that's a time savor when you are micromanaging woodlots and need to ensure deer can move freely throughout these mazes we create.
