Meadowlark,Why don't you just rent a trak hoe? I rented a 320 cat with 200 hours on it last week for 1700 per week or 40 hours.I used app 200 gals of fuel. You would not believe how much dirt those things can move.They delivered it 50 miles for 90 bucks each way.Very simple to operate,just don't get to close to the hole.Biggest problem is getting rid of the dirt like Kent says.
