Hand Crank Turns for Seed Rate Calibration
9
Weigh the seed collected during the test in kilograms.
Caution:
Scales must be accurate to 2 grams, as any error will be multiplied
by either 10 or 40, giving inaccurate calibration results.
10
Calculate the seed rate by multiplying the kgs previously collected x 40 (1/40th
ha method) or x 10 (1/10th ha method) depending on the requirement.
The seed rate should be correct. Large differences should be checked by
recalibration. If there are still large errors, empty the seed bin, check the
metering housings for wear or damage and start again from the pre-calibration
setup.
11
Small errors, due to seed coatings or seed sizes may be corrected by
adjusting the metering unit as follows:-
>Check and write down the
actual metering setting
on the metering unit.
>Write down the
actual seeding rate
that you calculated.
>Write down the
required seeding rate
(the number you
expected
from the
calculation).
Calculate the error and correction as follows:-
12
If the
actual seeding rate
that you calculated is
smaller than
the
required
seeding rate
then
increase
the metering setting by the
correction
amount.
13
Conversely,
reduce
the
metering setting
by the
correction
amount if the
observed or
actual seeding rate
is
more than
the
required seeding rate
.
Care must be taken when the metering setting is significantly reduced as
the unit can be damaged. If any resistance is felt, rotate the jockey wheel
when adjusting the settings down. If the toggle is set to ‘fine’ and the
settings needs to be reduced very low, empty the bin and start again.
14
Recalibrate from step 6.
15
Where a coated seed is used it is advisable to check the calibration after
1 hectare as dressings can tend to create a coating on the seed metering
wheels thus changing the the flowing properties of the seed which in turn
alters the seed rate.
