I own an 80 acre ranch on a butte in Oklahoma. It's rolling hills - some canyons so steep they can't be walked - with sandy soil and native grass. 20 percent is covered in oak (post and blackjack) and 30 percent is covered in red cedar. I intend to remove most of the cedar leaving some so the place looks like a heavily harvested Christmas tree farm. If I'm able to keep my job next fall, I'll be stepping up the mechanization of the process with a CTL and I'm looking for suggestions. I'm fine with purchasing new but I don't want to buy more machine than I need. Though it'll see 20 hours a week for a few years, after that it'll be used to maintain the place. Beyond the tree removal, I'll be grading trails and keeping up the 2-3 acre pond with excavation whenever it's lowered with drought. I'm thinking tracks over tires to minimize impact that could cause erosion and give better control over terrain. Whatever I purchase, I'll never operate it on paved surfaces. I'm thinking a tree sheer would be a place to start with attachments along with a flail mower that would chew up branches smaller than 5". It strikes me that working the trees will kick up a lot of pollen and mold warranting an enclosed cab. I'd appreciate any suggestions or considerations on brands and models.
