I am new to owning a tractor. I have a JD 5065e and looking to purchase a few attachments. First a Rotary Cutter / Brush Hog, Rake, and Box Blade. However, I am stuck with trying to find the best width for each implement. The tractor is 78" wide so do I need attachments that are wider then that? Would a 6 foot (72 inch) brush hog work? and the same question for the other attachments.
