Inspection in the field
Besides the setting in the metering unit, the plac
-
ing quality depends on further factors. It can be
adversely affected by external influences:
•
by the speed of the metering disc. It depends
on working speed and seed quantity.
•
by soil properties and changing soil condi-
tions.
•
by vibrations and erratic running of the drill
units; adapt the coulter pressure accordingly.
•
by setting and function of the trap roller.
Check the seed placement before starting
work and, when processing large areas, also
in-between.
¾
Drive the travel distance with constant speed
(approx.
1
50
feet
).
¾
Uncover the seed furrows of different rows.
After the acceleration phase the grains should have
been
placed at normal working speed.
¾
Uncover the grains carefully from the side, so
that they will not be displaced in the seed bed.
¾
Measure the placement depth and the seed
spacing.
The E-Manager shows the nominal grain spacing.
Any changes to the metering unit can influ
-
ence the placement accuracy.
Pay attention to the evaluation and the
display in the terminal, repeat the test se-
quences in case of negative changes.
Sowing soy
When sowing soy, the seed is not correctly de-
tected to 100% by the sensor.
The placement must therefore strictly be in-
spected in the field.
¾
Read the nominal seed spacing in the monitor.
¾
Calculate the nominal seed quantity per
meter.
Example: Nominal seed spacing 2 cm
g
100 cm : 2 cm = 50 seeds/m
¾
Open 1 meter and count the seeds.
(= actual seed quantity)
¾
Compare the nominal seed quantity with the
actual seed quantity.
¾
Adjust the nominal seed spacing, if necessry.
Changing the setting
Seed problems and faults may be encountered
in grain pick-up (1), on the scraper (2) and in
grain trasfer (3).
