on the culture Seed plate and ring
Always use the adequate seed plate-ring
for each seed that are about to be sowed.
It is important to mention that due to the
diversity and format of the cultures, the
seeds must be well placed and in a way
that only one fits the hole.
Seed metering
Seeds treatment
Treating the seeds with oil or liquid
inoculants applied directly to the hopper
may compromise the system efficiency.
Locking seed ejector
Check the conditions of the seed ejector
and clean the brush to assure a good
functioning.
Brittle seeds (milling)
Check the graphite utilization during
operation, as well as the adequate choice
of seed plate and ring.

Never remove the weight limiter from the
metering to avoid overloads and physical
damages to the system.
