My farm of ~100 acres is being overrun by black locust trees. If you are not familiar with the species these are thorny hardwood-like trees that grow up to 6 feet per year. If you cut them down at the base of the trunk the hardwood is heck on a chainsaw and the thorns are heck on your arms and they re-grow sprouts from the roots with fury so the only way to get rid of them is 1) spray them with Remedy/Relegate when they are small to kill them or 2) rip them out of the ground with something like a dozer and then spray any sprouts that come up. The majority of my pastures look like the photo below that I took today below. Aside from clearing brush I also have another big need for a dozer. In my neck of the woods in NE Texas we're having a time with hogs tearing up pastures. When the hogs come it looks like carpet bombs have been dropped down on my fields. The best thing for that is a dozer to smooth out the ruts and an AR15 with night vision. With all that in mind, would you consider hiring a dozer operator to come in and pile up the trees and smooth out the hog runs from time to time, rent a dozer for a couple of weeks and do it yourself, or if you had the money would you buy a dozer to keep on the farm whenever you needed it? If you went with buying a dozer, what size would you consider given my situation? I don't have experience operating a dozer nor working on heavy equipment so that's something to keep in mind, though I'm fairly handy and could probably figure both out.
