I have ben thinking about getting a brush or flail type mower for my KX121, Not really sure what to to look at and what to avoid. Im going to be using it to trim back the sides of my road...about 1000 feet on both sides. Mostly smaller pine branches and scrub oak chutes 2-4' feet tall and small branches.May also use it to maintain the low areas we already cleared so they don't get overgrown again.. Anyone have any experience with them for this type of use ?
