As Thermo said get some pic's.
I can't really see a moler hole working through clay as we use these and they work by forcing and compacting the soil to the sides
all round the mole which then won't let the water through.
Later this year one job on the cards is 6,000 meters = 3.72821969697 miles of land drain and this will be done by trench, pipe and
stone back fill, not one we're looking forward to as its an hour + drive away and it will take a few weeks to do.
Apart from the digging the hardest part of what you want to do is the fore planning and the setting out,
and to do this there are several good people that post on here that would help with advice, if you need it
