I've accumulated a modest collection of bucked trees in my backyard. Most of them no more than 20" diameter of locust and oak. The trees keep coming and I need to catch up on the cutting and splitting. My Husky 18" 455 Rancher just died. It had been used pretty harshly for several years. Will the MS-290 with a 20" blade be enough to cut 2 or 3 cords per year of this kind of stuff? Don't want to overbuy on the saw.
