have been used, a pair of disc hillers can be attached to any rigid rig type 

 of cultivator for the last operation. These disc hillers when run at a 

 reasonably shallow depth, say from 1^ to 2 inches, will throw enough soil 

 to cover any ordinary-sized weed. 



The type of shovel to use is well worth considering. We will assume 

 that corn should be cultivated, not plowed. The ordinary type of 

 shovel plows the ground, or, in other words, it throws the dirt and leaves 

 a furrow. This is admissible when weeds have made a rank growth 

 either because of neglect or continued rains, and the only way to eradi- 

 cate them is to cover them. Under ordinary conditions, however, the 

 ground should be cultivated and not plowed. 



The type of shovel known as the slip-point hoof shovel is ideal to do 

 the work the first time through, and for subsequent cultivations, if 

 properly adjusted to depth. The hoof shovel used on the six-shovel 

 cultivator measures at the extreme cutting width 4f inches. This 

 shovel will cut full width, penetrating to a depth of two inches. For the 

 four-shovel cultivator, the shovel measures 6j inches, and will cut 

 full width running at a depth of 2| inches. These shovels can be 

 gauged to run five or six inches deep or two inches. The attractive 

 feature of the hoof shovel is in its shape. It does not throw the soil, 

 but stirs it thoroughly and leaves the surface free of ridges. The hoof 

 shovel should be used for the first cultivation, and the sweep shovels 

 thereafter if the ground is reasonably free of trash.

The half-sweep, or front sweep, for the shovel cultivator measures 6^ 

 inches wide, and the full sweep for the remaining shanks is 9 inches wide. 

 The half-sweep for the four-shovel cultivator measures 8 inches wide, 

 and the full sweep for the remaining shanks, 13 inches. The sweep is
