Ditto on what Hugh MacKay said. Fine tuning in the field is key.
Here's something I've learned from experience and you won't find in an operators manual: Sharpen your coulters with an angle grinder. It will make a huge difference in feeding trash through, covering trash, and improving your coverboard or coulter jointer performance. Dont make the edge paper thin, but put a blunt sharp edge on it. Once you've plowed with sharpened coulters, you will then be able to recognize when they need to be sharpened.
Also, if you still can't get a clean furrow wall, dirt is boiling over onto unplowed ground, and the plow covers trash terribly no matter how you adjust the coulter, look at the slop in the coulter. Play in the coulter blade bearings and play between the fork and the shank are enough the make the coulter blade wobble (though not visible) enough to cause the above described problems.
One last thing, no matter what old coulter you will find, the shank or the fork will be bent so the blade doesn't run perfectly perpendicular to the ground. So will have to shim under the clamp to make the blade run true.

Farmallb: I agree with MF Poor and JMS on parallel distance from shin, point or land side. Too close will cause excessive wear of landside and shin. Best to use a straight edge along landside and point in the shop, set it 5/8" to 3/4" then fine tune in the field.

Forward and aft the coulter axle should be directly above tip of a new point. Depth depends on how deep your plowing, 4" of penetration is ideal.

I don't buy all this bunk about them not being required in different situations, even single bottom plows. Rolling coulters vastly reduce wear on points, shins and landsides.

i've never been around many plows with colters, but my plow has holes for them and if you put them on with the clamps the only adjustment you have is depth control. do they make some shims or spacers to set the width with?

What kind of plow do you have? Never saw one without provisions for coulters. The distance was changed by the two 90 degree bends in the shank, I suppose that could also give fore and aft adjustments.

3/8" to 5/8" left of the leading edge of the shin. If your plow is equipped with coverboards (trash boards), you want the coulter to be 3/4" to 1" left of the shin. Set accordingly to the best over-all performance. Coulters should be set at a depth where they cut surface crop residue, or where they cut the bulk of the roots in sod. 2" to 4" is PLENTY deep enough.

Set the rolling cutters in modern times so the trash will feed through the plow. The plow was the first form of weed control and the plant from the previous year was a weed. The rolling cutter was not generally used on single bottom plows. They were used to get a clean, smooth cut of the furrow so the sod or whatever would turn over completely to kill the previous crop. After the intro. of chemicals,the increase in yields and the increase in the amount of trash the plow had to deal with, the rolling cutter became more important in its aiding the trash feeding through the plow. We now have a situation where size matters, the first answer was the notched coulter, it helped some, but was not the answer. We would set the coulter right or left, up or down to get the trash through. They then increased the size of the coulter and the throught of the plow to handle the trash, if you get a chance compare the spacings on your plow to an I.H. 720. So the real answer is, set your rolling cutters so your plow will do what you want, up or down, right or left. If it's used maybe it,s OK already. Good Luck.

The single bottom plows that did not have a rolling coulter were early horse drawn walking plows and they had a knife blade mounted from the share up as the rolling coulters had not yet been invented, starting with the sulky riding plows for horses they had the rolling coulters and all tractor plows to follow had the rolling coulters

It also needs to be able to pivot a little to the left and a lot to the right of straight ahead. The dirt rolling off to the right has a tendency to pull the cutter to the right.

Typically set about 5/8 inch to the left of the point of the plowshare, and somewhat above- dimension which I do not remember! Certainly don"t want it to hit.

Right centered with the height at which it cuts on the plowshare. Imagine if you set at plowing, stop in the middle of a row at full depth then install it to cut the depth it should. Also, it should definately be in front of the plowshare and parallel with the furrow.
