Figure iiA represents two shares. No. i represents 

 a share set for spring plowing, when the ground is soft. 

 Notice the heel of the share following the square for 

 about one inch at c, while the heel in No. 2 rests with 

 the extreme edge on the square, and is set for fall 

 plowing, when the ground is hard. The line between 

 a and b shows the suction at d, which is not more than 

 an eighth of an inch. Breaking plows and large plows 

 which are run shallow should have a wide bearing at c. 

 In breaking plows the heel will sometimes have to be 

 rolled up a little at this place.
