PHOTO - plough furrow press

Hi gang;
For you guys who are unfamiliar with this system of ploughing & pressing at the same time, this photo shows what happens (the tractor has reached the headland and has raised on 3 point - released the arm on side of plough off arm on press)
The plough will turn over hydaulically clockwide so the press arm will go over the top. Then when the tractor returns and lowers the plough the arm on the plough catches on the arm of the press.
There is a 3 point hitch on the press itself which is used on front 3 point to tansport the oufit from field to field.
The press is 2 rings (Flexicoil) spirals which beak down & compress the furrows.
For all you guys who know what it is - sorry to bore you.
98% of all ploughing here is done with reversible ploughs, up to 12 furrows on back in semi mounted form.
Cheers David
