Yeh, I know it is going to be a PITA moving it every few feet of trenching...I may rent a mini ex for a day or two to finish the trenches if I use the tractor to just dig to 5'.
My problem is hidden boulders/rock...may take a while to determine where to actually make the trenches and it gets expensive renting a mini for weeks or a month...contractors I talked with larger excav. want per hour pay and not a per job agreement...a $1G est. could become 4 or 5G
Thats for that location Chuck
