WHEAT 167 



drill. It is a good drill in a clean well prepared 

 seed bed. 



The disk drill has the advantage of the shoe 

 drill as a trash rider, since in place of the shoe 

 a revolving disk rolls through the soil, riding over 

 or cutting under trash and opening a neat furrow 

 in which the seed is deposited. The disk drill 

 draws a little lighter than the shoe drill and has 

 a special advantage in trashy land or hard ground. 

 The double disk does nice work in well prepared 

 land which is not too hard or trashy, but the 

 single disk is superior in hard or trashy ground. 



As a general drill for use on all kinds of ground 

 the writer prefers a good single disk drill, but the 

 double disk drill and shoe drill have some ad- 

 vantages for shallow seeding, as in sowing alfalfa 

 or grasses, since their depth of seeding may be 

 better controlled. 



Drills are manufactured which make the furrows 

 5, 6, 7 and 8 inches apart. When the shoes or 

 disks are seven to eight inches apart the machine 

 is less likely to clog. The standard drills more 

 commonly used make furrows six or seven inches 

 apart. 



Drills and seeders are made in standard widths 

 varying from eight to fourteen feet. Single drills, 

 three feet wide, for sowing wheat between the 

 rows of corn are also in common use. In the 

 Red River valley four and six horse machines 

 having a width of eleven or twelve feet are used. 

 One man with a good team can sow thirty acres 

 per day with one of these large machines. 



Grain drills may be purchased with grass seeder
