[AT] 3 pt backhoe

[Don Bowen]

I need to dig about 600' of 6' trench for a ground source heat pump, 
excavate a foundation and maybe dig a drain field.  With two tractors 
around here I wonder if a three point backhoe would be worth the 
investment.  How much tractor do one of those typically require?  I know 
where I can borrow one and have seen a couple of CL but do not know the 
power requirements.  Is there any sort of rule of thumb regarding boom 
length and bucket size?

This is the Ozarks with lots of rocks.  Bedrock is not very far down but 
the area I plan to dig is the bottom of a little valley where there are 
fewer rocks and a 6' excavation the PO did for a basement did not hit 
bedrock.
