Hello, I am a new member and a rookie tractor owner. I just need advice as to what is a better attachment for my tractor. I have 6 acres and it is out of control weed and grass wise. I have goats and sheep but they can't keep up especially during spring so I am trying to decide between a 4"' frail or rough mower pto attachments. Ground is level for the most part. Any arguments in favor or against would be appreciated.
