threshed and the ground is plowed. The disk is used very 

 regularly on fall-plowed land and on fallow land. It is a tool 

 that will do many kinds of work, according to the angle that 

 the disks are set. By putting them almost directly upright, 

 they simply slit the ground, and by setting them at a heavy 

 angle, they almost completely turn the surface. 



Our people have learned to use them in loosening up sod- 

 bound meadow lands and alfalfa as a means of bringing new 

 vigor to the old sod. 



Every farm in our commonwealth should be provided with 

 at least one disk harrow as a necessary part of its equipment. 

 I believe that in the future our farmers will learn to use them 

 more regularly than they are doing at the present time. And 

 they are now adapted to a large number of uses which they 

 were not put to ten years ago.
