PLOW BOTTOM METALS 



131 



The toft of a steel share is perfectly smooth and has as uniform hard- 

 ness as it is possible to make. 



Plow gunnels with and without 

 a piece of steel welded on the 

 bottom for reinforcing the point. 

 This metal is of the proper carbon 

 content to help keep the point from 

 wearing upward on the bottom. 

 It is illustrative of the efforts put 

 forth by plow makers to make steel 

 shares as durable as possible. 

 The projection on the edge of the 

 gunnel gives a wider welding 

 surface thereby making the share 

 stronger.

 of steel on the finished product. This gives strength and additional wear.
