LINE OF DRAFT. 



In illustration Fig. 81, page 14, is given the method of obtaining the correct 

 draft on plow. A line connecting centre of draft A in mold board with attach- 

 ment at bridle should line in the plane of the traces as shown by A, B, D. If 

 it becomes broken, as in A, C, D, or 1, 4, 5, instead of 1, 2, 5, the draft of plow 

 is made heavier.
