Deviations between the adjusted and the actual seed rate
Possible reasons for the deviation between the pre-set and the actual
seed rate:
•
For the adjustment of seed rate, the accumulation of the worked
area or an indication of forward speed
AMATRON 3 / AMALOG
+
requires the impulses of the seed drill drive wheel over a meas-
ured distance of 100 m.
Slip on the seed drill drive wheel may vary in changeable soils
(e.g. from heavy to light land) resulting in a change of the value
of ‘Imp./100m’
In case of deviations between the adjusted and the actual seed
rate, the calibration figure "Imp./100m" should be re-determined
by driving down a test distance.
•
Sowing moist dressed seeds may result in deviations between
the adjusted and the actually sown seed rate, when there is a
period of less than one week (recommended 2 weeks) between
dressing and sowing.
•
A defective of wrongly set metering lip (Fig.
127/1) will cause metering faults.
Set the metering lip in such a way that it
slightly rests an the metering roller (Fig.
127/2).
