64 THE AMERICAN APPLE ORCHARD 



Harrows Spading, cut-away or disk harrows are 

 now deservedly popular among fruit growers. These 

 all have the same general form. They differ chiefly in 

 the character of the disks. In the original cutaway 

 harrows simple concave disks are used. In the more 

 recent spading harrows these disks are cut into several

sections, each section acting like an independent spade 

 as the disk rolls on its way. This latter form gives 

 much better results on hard soil. It is adapted to 

 deeper and more thorough working of the ground. 

 For light surface tillage, such as is most desirable in 

 preserving the dust mulch for the conservation of 

 moisture, the plain disks are doubtless better.
