THE ROLLING COULTER 



161 



This illustration shows the effect of a plow out of adjustment on the 

 rolling coulter. The rolling coulter is always pulled in a straight line 

 of draft. The bottom as is illustrated by the landside shows that it is 

 wording out of its true line of draft. The clods and earth on the edge of 

 the furrow bank are telltale evidences of the wrong plow adjustment.
