The diagram on 

Fig

ure shows a sowing disc that allows two seeds to fall into each cluster. 

The  suction  holes  in  the  first  row  are  in  a  circle  of  diameter  d

1

,  and  the  suction  holes  in  the 

second row are in a circle of diameter d

2

. 

The number of holes in both circles is the same, but the holes in the second row are placed at 

an angle γ relative to the holes in the first row, pushed in the opposite direction to the direction of 

rotation of the disc, and the two holes in the two circles form one group (Fig.).

 

The vacuum stop 

line  to  two  same  group  holes  in  the  shell  of  the  sowing  apparatus  is  placed  so  that  the,  seed, 

which was sucked into the hole located in a diameter d

1

 circle, get rid of the vacuum and separate 

from the disk first, and then the seed in a hole located in a diameter d

2

 circle is discarded second.
