How could I unclog this drain? I thought of getting a pressure washer
and shoving it up the outflow I found in the ditch. Any other ideas
would be apprecitated.

I have a fairly beefy Kaarcher with the drain-jetting hose attachment.
I'm very glad I got the 'long' version (around 75ft.), as I've need to
use it's entire length on a couple of occasions. It's done a brilliant
job on our salt-glazed (clay pipe) drains (slowly getting replaced with
plastic).

I also had a cast-iron downpipe concreted into a gully trap. Both were
solid with grit, moss and other crud off the roof, to a depth of 2' up
the pipe (tried to rod it, which is why I know). The drain-jetting
'bullet' cleared this completely after about 20 mins of soggy poking
about.

So I'd heartily recommend them from my own experience, BUT clay land
drains are notorious for cracking and collapsing, and becoming conduits
for tree roots (in search of the water). If the drain is intact, a
pressure jetter might well clear it. but if it's collapsed, you'll have
to dig it out and repair it. It's annoying that the hose can't be
extended (it goes straight into the "gun" of the jetwash) - I have an
extension pipe for the jetwash itself, but that's no use in this
context. The 'pro' versions have much longer pipes, so hiring one might
be a better option.
