The standard depth for Duke Power is 30 inches.  Yours may vary.  If I 
could have gotten a machine in here to dig, the rent for a trencher that 
will cut 30 inches deep is $175 per 24 hours.  The power company will 
dig it for $350, but wants to use a trackhoe.  A grading company may 
have done it for less than $350, but I started after finding no better 
solution than manual digging.  The challenge seems to be getting a 
machine in here.

My concern is that something may fall from the tower and slide down the 
roof into the power lines that connect to the house.  My tower will be 
on the side adjacent to where the power lines connect.  I doubt that the 
tower would fall into the lines, because the house is in the way.  That 
won't keep a dipole or guy from falling during construction or installation.

It took no more than an hour to dig the tower base by hand.

In theory, theory and practice are the same.  In practice, they are 
different.
