Hi,
I am looking at buying a Speeco post hole digger and the model I think, is 70 -
yellow painted frame. Also a 12" auger as well.
From what I can determine, this PHD and a 12" auger will dig a 45" deep hole.
Does anyone know if this is true ? If it is, can an extension be put in between the auger and the gearbox, to lengthen the hole depth ?
Reason I am asking is the the local building code where I am, says that the concrete piers for wood post (for decks, carports etc.) must be at least 4 ft deep for gravel to 6 ft deep for clay soils. I need to drill 14 or 16 holes for both a carport and a deck entension and want to get down to at least 5 ft so I can use a sonotube filled with concrete.
So, can say a 12 " or 18" extension be fitted to lengthen drilling depth - safely ?
Drill the first hole, the extend the length with extension to go deeper. A slow process, but is it doable ??
I am new to PHD - hence the question. I don't have a backhoe so the only other option is diggin by hand in clay soil - not good. My tractor works fine so a TPH PHD seems to be the answer. I am 45 miles out of town so getting someone to drill them for me would be prohibitive.
Any info or advice would be greatly appreciated - cost is a factor, so the Speeco seems affordable. I am sure there are much more expensive ones around.
Thanks
Jim
