PLOW BOTTOMS 



117 



A section of the furrow shown in the illustration on page 116 cut 

 farther forward, showing that the plow bottom has forced the furrow 

 slice to conform to its shape, thereby beginning a stretching operation on 

 the bottom of the furrow. Observe in the illustration on page 116 that 

 after the furrow slice has reached the ground the freshly stretched 

 furrow slice bottom is helping to put pressure against the top. 



A plow bottom which does not have the proper shape to force the 

 furrow slice against its surface so that the pressure is equal on all parts 

 of the plow bottom. This illustration shows the importance of having 

 a plow bottom adapted to the soil. The shin is doing the greater part of 

 the worfy.
