Using a Tractor and Auger
A tractor outfitted with a 3-point
hitch will accommodate an auger. The typical tractor
should be at least 25 HP. The auger attaches to the tractor
and normally the weight is sufficient to dig the hole. A
hydraulic power unit is available to add a downward force, but is
not usually needed in most situations.
Augers are available is several
diameters. For fence post, we recommend a 12" auger,
especially when working on slopping or somewhat rocky soil
conditions. The 9" auger is large enough for the post,
but the extra room of the 12" auger allows for repositioning of
the post in the hole. Also on hillside, it is difficult to get
the hole dug straight down.
When selecting an auger, choose a
good quality one with replaceable cutter blades. These will
wear done with several dozen holes. Dull blades simply won't
cut in.
