" This harrow is six feet in width when expanded, but when 

 closed for transportation is less than two feet. It is seven feet 

 long, and weighs one hundred and fifty-five pounds." 



THE CULTIVATOR. 



There are various modifications of this tool, but its general 

 form is always similar to that shown in Fig. 97. The teeth may

be made of various forms. Sometimes the common harrow teeth 

 are substituted, and sometimes shovel-shaped teeth. It is a good 

 improvement to use, in the place of the hindmost teeth on the 

 arms, a pair of the small shares of the horse-hoe, shown in Fig. 98. 

 The cultivator is used in working between the rows of corn, 

 roots, etc., and is very much better for this purpose than the 

 plow. 



In the large corn-fields of the West, a great deal of hard work 

 is saved by the use of a sulky cultivator, on which the driver 

 rides. These are sometimes made wide enough to cultivate two 

 rows at once, and drawn by two horses. It is stated, however, 

 that the cultivation done by this tool is far less complete than is 

 desirable, and that it is less popular than when first introduced.
