GROUND DRIVE - CALIBRATION

Introduction
The calibration procedure involves the
rotation of the metering system by hand to
simulate the coverage of a certain area. A
material sample needs to be collected and
weighed to calculate the application rate. This is
done by taking a sample equal to 1/20
th
of a
hectare.
It will be necessary to disengage the drive
system for the main air seeder when calibrating
the pasture planter.
For more detail on calibration refer:
Air Seeder
Operator’s Manual, Ground Drive – Calibration.
When calibrating, ensure that there is
enough material in the Pasture Planter Bin. In
most cases 1/2 a bag will be sufficient.
It must be remembered that this style of
seeder is dependent upon a correct wheel
diameter for its operating accuracy. If this
diameter is altered, (e.g. incorrect tyre fitted,
wrong tyre pressure or extreme ground
conditions), inaccurate metering may occur. If
extremely accurate metering is desired refer to
Air Seeder Operator’s Manual, Ground Drive –
Calibration -
Method C for checking the wheel
circumference.
Meterbox Adjustments
It may be necessary to make adjustments
to the pasture planter meterbox when metering
low or high rates of seed. The meterbox has
been supplied with a reducer plate (yellow) that
is fitted to the front face of the meterwheel
opening. This plate is suitable for light to average
application rates of small seeds. This plate
should be removed when metering high rates of
seed or large/light seeds (eg. rye grass).
As a guide, the variator setting should be
between 1 and 7 after calibration. If the setting is
too low you may need to fit the reducing plate if
not already in place. If the setting is too high,
above 7, remove the reducing plate if fitted and
recalibrate.
When using product that has poor flow
characteristics or larger seeds it may be
necessary to remove the meterwheel cover
plate. Refer to the adjustments section of this
manual for further information.
Calibration Procedure
Step 1. Open the bottom door of the Pasture
Planter.
Fig.17 Bottom door on pasture planter.
Step 2. Fit calibration collection bag to the
p/planter meterbox using the draw
string.
Fig.18 Fitting the calibration collection bag.
Step 3.
Disengage drive pin from the seeders
main bins.
