Hi
I need to install 7 fence posts, I want to do them AS FAST AS POSSIBLE!

They are 9 foot posts

As I understand it I should aim to do a narrow hole as possible. But I have
also read I should stick some hardcore down there to help hold it in place -
doesn't this mean I should dig the holes a bit wider than the post itself?
or they just mean smaller rubble?

Anyhow, which tool will do it for me the quickest?

Thanks!

Frankly none of the above. Go to your nearest tool hire company and
tell them what you want to do. They will have a post hole borer you
can hire that will do the job with the least effort and greatest
efficiency. Yes you must make the hole bigger than the post so that
you can put some concrete in it to hold the post securely particularly
if they are nine foot posts!

I'm not sure I'd like to try holding a powered borer on my own. I think
they are really a two person device. A lot will depend on the local soil
conditions, few stones or rocks and just "earth" might not be to bad.
Heavy clay or scattered rocks could be interesting when the bit jambs and
the engine rotates, or tries to.

Don't see 'em putting concrete around telephone or power poles... Snug
hole with rammed soil/rubble around will hold a post, provided it's put in
deep enough. A 9' total post needs a minimum of 2' better with 3' in the
ground to be stable. If the ground is very light and soft you may need
more depth.

"Postcrete" or similar poured in dry around the post in a snug hole and
settled in by waggling the post and a some tamping is less effort than
ramming earth. The damp in the soil will set the 'crete and the post will
be held before it's set anyway.
