I'm sure. You might rent a little two-man auger and auger a hole next
to it, or put an old chain on a saw and cut it into pieces.

I've gotten down
about 17 inches and the post is going to rise about 38" off the
ground. Is that enough?

Sounds like a decorative fence, that should make it last until you're
dead. If you have livestock and they lean into it it'll last maybe a
week.

I've been reading that I should use gravel as
a base is that recommended or will just backfilling the dirt be good
enough to hold it?

A couple inches of gravel in the bottom will aid drainage, tamping ALL
the dirt back into the hole should hold it until you're past post
replacement age.

how about along the sides at well, will that enhance the life of the
post? I noticed a bunch of tree and bush roots had made their way
through the old post.
