I need help setting up a 3pt sprayer for my 50hp tractor, so I can spray roundup on my many feet of fence line. My fence is a simple 5 ft tall metal post with 3 rows of barb wire. I would like to spray 14 ft at a time, 7 ft behind the tractor and 7 ft through the fence. This would take care of both sides in one application. Would it be better to set up as a boom-less sprayer and spray through the fence or a boom sprayer for better drift control?
