Nah, a machine would be more troubs than it would be worth. I have about 15 x 4ft deep holes to dig, the 'new fence.'
The neighbors had their own survey now, once again confirmed, so it is a tactical fence to over take new lands. It involves concrete breakage, precision shed di-sections. It is better to do in sections i figure. So about 5 holes a day and set the concrete footer. 5 holes dug a day will keep the doctor away.
