dirt, and often cuts to a depth of several inches. Its best work 

 is generally done with three or more animals, though two 

 animals may do well on a harrow with no more than 8, 16 or 

 18-inch disks. When cultivating crops there is no necessity 

 for more than two good animals. 



As a cultivator, the reversible extension head disk harrow 

 cannot be excelled. The gangs can be used close together or 

 wide apart; the gangs can be arranged to throw the dirt towards 

 or away from the plants and to work higher or lower on the 

 inner than the outer ends and vice versa; they can be set to 

 throw ridges to the plants or set to "bar off;" they can be set 

 to cut shallow close to the plants and deeper near the center of 

 the row. 



The action of the disks upon the soil makes the disk harrow 

 a most excellent cultivator. The disks thoroughly pulverize 

 the surface of the s'oil, destroy the grass and weeds, leave the 

 under soil compact and a fine soil mulch spread all over the land. 

 The roots of the growing plants are undisturbed, especially 

 when the inner ends of the gangs are set higher than the outer 

 ends in cultivating plants on beds. 



For cultivating cotton, potatoes, peanuts and other crops 

 that have to be hilled, the disk harrow is especially valuable 

 because it can be set to ridge the hills at the right height and 

 the dirt which is hilled around the plants is thoroughly pulver- 

 ized and cultivated, so that only fine soil makes the hills. A 

 fender may be used when cultivating small crops. The disk 

 harrow is probably the best implement to use in hilling cotton 

 and other crops grown on ridges. 



A turning plow is out of place in a crop. If the soil is 

 devoid of vegetable matter and runs together after a heavy rain 

 or if it rains for two or three weeks and it becomes necessary to 

 bury grass, we can give a large angle to the disks and set the 

 gangs to outthrow and "bar off" the little cotton or other small 

 plants or we can set the gangs to inthrow and give the disks the 

 necessary angle to cover the grass and weeds and thoroughly 

 pulverize the soil. One man with two horses and a disk harrow
