Operating The Air Seeder

While the blower is warming up
check
that the meter shafts turn freely.
Refer to
the “Metering System’ for further details.
IMPORTANT
On
cold
wet
mornings
it
is
recommended that you run the blower at its
operating speed for at least 10 to 15
minutes before seeding. This extended
start-up time will help dry the distribution
system if moisture is present.
It is suggested that the operator does
not lower the points of the implement into
the ground until the machine is moving.
This will help in preventing the sowing
boots
becoming
blocked
in
muddy
conditions.
Engage the clutch on Ground Drive
Models or take monitor off hold on VRT
Seeders when you wish to apply material.
To stop seeding, simply turn the clutch off
or place monitor on hold on VRT Seeders.
This will disengage the drive system.
Monitor Operation
The monitor system is different for the
Ground Drive and VRT equipped seeders.
The operator should read the specific
monitor manuals supplied for all technical
information on installing and operating the
many features of each unit.
Before the monitor can be used the
appropriate sowing width needs to be
loaded, and for VRT seeders, a calibration
procedure performed.
To obtain basic information and the
preset values used on your specific model
supplied, refer to either the Ground Drive-
Monitor Operation section (page 32) or the
VRT Hydraulic Drive section (page 64).
1020 Air Seeder Monitor
The main function of this monitor is to
show the operator that material is being
conveyed through the system to the
secondary head and warn against a
blockage in that secondary distribution
hose.
The monitor should be switched on
before operating the seeder. The toggle
switch on the front face of the monitor
should remain on “RESET”

Head Blockage Kit
The Gason Air Seeder is supplied with
one head blockage sensor (GPN 208651)
and harness. This can be expanded to 21
sensors at a later stage if necessary.
To operate, adjust the sensitivity
knob while conveying product so that the
monitors red light and audible warning
stops. If the red light comes on, check for a
blockage.
When finely adjusted the light will
sometimes flicker when the tractor slows or
turns. This is caused by either the material
rate dropping off because the drive wheel
on the seeder has slowed or fan speed has
reduced because of other demands on
hydraulic oil flow i.e. steering/implement lift.
The sensitivity of the monitor is such
that the system will pick-up this small
difference in the material rate or velocity.
