Introduction (VRT Hydraulic Drive)
The VRT Hydraulic Drive metering
system fitted to the air seeder will allow the
operator to control product application rates
from the tractor cab.
The
Gason
VRT
(variable
rate
technology) system uses hydraulic motors
to rotate the seeder’s metershafts. A
special
hydraulic
manifold
assembly
controls oil flow from the tractor’s hydraulic
system to vary the different metershaft
speeds. The Farmscan 3000 & 3500
monitor and seeding pod is the control face
of the Gason Hydraulic Drive system.

This section will look at the specific
information required to operate the monitor
for the Gason VRT system.
It is recommended that the operator
reads this section of the manual and views
the ‘VRT Training Video’. The laminated
‘Quick Reference Guide’ should be stored
in the tractor cab and used to remind the
operator how to calibrate the seeder when
in the field.
Farmscan have also supplied an
operator’s manual with the monitor. This
manual covers relevant information for the
control system and its operation. It will not
however give detailed information regarding
the calibration and setup procedure for the
various products to be sown using your
Gason seeder.

Monitor Installation (VRT)
Refer to the Farmscan operator’s manual
for specific information regarding the physical
installation of the monitor to the tractor.
Setting Implement Width
The Air Seeder and monitor have been
fully tested and the software setup at the
factory to suit your specific model air seeder.
The only setting required by the dealer or
operator before calibration and operation is
the implement’s seeding width. This
information can be entered into the monitor
by going to the menu screen. Push the ‘CAL’
key on the front face of the monitor.
