- The fertilizer position related to the seed must be carefully observed.
NOTE
The furrow opening is made by the unaligned double
discs (A and B), which allows the fertilizer placement always
next to and below the seeds.
To change the fertilizer distance related to the seeds, it is
necessary to displace the fertilizer row on the frame, as well as
its rod.
These unaligned double discs feature flexible internal scrapers
(C) which have automatic adjustments to remove the dirt that
accumulates in their internal part.
The fertilizer depth is adjusted by
the limiting bushings (D), found in the
spring rods. The working pressure is
already determined by the rod course
and spring length.
