My cousin is a logger and he calls his chainsaw a deer call. When he is cutting trees down they are right behind him, literally, browsing the tree tops. The disturbance won't bother them at all as long as you don't chase them with the chainsaw!

I have cut lanes for trails and shooting and the deer immediately started using the trails I cut. You will also attract them as the trees you cut will sprout new shoots from the root stock and provide browse next spring and fall.

As far as the no till, keep in mind that in order for that stuff to sprout and survive, they still need a ph range that will allow them to grow and thrive and be palatable for the deer
