THE OLIVER PLOW BOOK 



In shafting the point of a plow share the greatest care should be ex- 

 ercised to see that it has a gradual wedged shaped slant. One of the 

 difficulties encountered when carelessly sharpening shares is to put the 

 point of the share oser the edge of the anvil, then hit it a blow with a 

 hammer. The result is worse than the equivalent of a dull share. 

 Instead of the ploio going in deeper as intended, it gouges along the 

 ground and increases the draft of the plow. The illustration shows 

 the proper angle and shaping of the point. 



The wing of the share when properly sharpened, rests on a straight 

 edge with the point. The edge of the throat is slightly raised from the 

 straight edge. This means that when the plow is operating in the ground 

 the point is as much low as the throat is high on the straight edge.
