Ok, this was suggested to me by someone who's opinion I don't necessarily trust so help me out. Is it safe/ possible to take down a small tree or shrub with a walk behind? I'm talking about a trunk maybe 3 inches in diameter. I have a 3 month old Exmark 36 Kaw 15 hp hydro. Not wild about doing something that could damage it. Anybody done this? If so please explain. Thanks.
