southern MN | Old coulters had a wishbone frame, not just on the back side. Tie the wire to the coulter bracket down low. Leave the wire long, longer is better. Needs to be long. Good stiff wire.
The wire needs to flow over and into the bottom of the furrow in front of it, long wire will burry itself and hold down in the bottom of the previous furrow. Too short a wire and it won't stay down in the furrow.
It folds over tall cover crops, like alfalfa and sweet clover. Burrows all the green manure. Typically this was done in late spring, and you wanted everything buried, so you could work it down in a few days and have a black field to get planted into, not so much herbicides and didnt have time to let things die off that were sticking out of the ground. You wanted the green stuff folded down.
So the wire would fold the green stuff over and down flat, so it would roll over and be buried. Otherwise you'd have a green slice that tipped up and stick out of the ground. Cover boards sorta do the same thing, but not as well for this purpose, the wire worked well.
It didnt help for cornstalks or heavy dry trash, only for standing green crop.
Plowing clockwise and it worked all day. Plowing counter clockwise and you would end up dropping the plow on the wires and cutting them off too short with the bottom behind....
