Ive had a 20" 290 Farm Boss for the past 8 years, its been a great saw for occasional clearing projects around the farm. We just had our woods logged and now I find myself facing the task of turning 8 acres of mostly Ash tops into firewood, somehow I think my trusty old 290 better sit this one out. Ive been eyeballing a 361 at the local dealer, 20" bar is all I will ever need, will I notice a night and day difference between the 290 and 361 or will the gains just be minimal?
