can take a row of cotton or corn at one time and destroy the 

 grass and weeds and make a fine soil mulch out of the hardest, 

 sun-baked soil. An extension standard is furnished with the 

 latest reversible extension head harrow which raises the frame 

 high -enough so that cotton, corn or other crops can be "laid by" 

 with this implement. 



The gangs can be set at different angles for hillside cultiva- 

 tion. This is a very important point to the man whose farm is 

 in a rolling 1 country, as he will appreciate the fact that a disk 

 harrow, particularly in loose soil, will tend to work down the 

 hillside. This can be obviated by setting the uphill gang to 

 work with a little greater cutting- angle than the other g-ang; 

 thus causing the harrow to work in a straight line on the hill- 

 side. 



The double disk harrow is desirable for farmers who wish to 

 do two diskings at the same time. It has four sections, two of 

 which throw the dirt out, followed by two more which throw the 

 dirt in, leaving the land level and smooth after its use. The 

 land is generally left somewhat ridged with the single disk even 

 though half, as nearly as possible, is lapped on the land already 

 worked. The double disk requires more horse power than the 

 single disk, but the ground is double-disked in the quickest 

 possible time and left in a very fine level condition. The main 

 advantage of the double disk other than saving- labor is that 

 you can remove the rear attachment very quickly and easily, 

 and convert it into a single disk harrow. 



The cutaway harrow is a disk harrow with the edges of the 

 disk notched or with portions of the disks cut out. This lets 

 the remaining- portions cut deeper into the soil. It is useful in 

 cutting up sod and also in hard and rocky ground as it pene- 

 trates better and gets down between the rocks where the plain 

 disks would roll over the rocks. It does not pulverize as well 

 as the solid disk and hence should seldom be used when the 

 other will do good work.
