can be replaced at any time, if required,
without splitting the bins.
The trailers are built from 350/450-
grade rectangular hollow section with either
side plates or truss system for stiffening. It
has been designed and tested to reduce
the possibility of rearing if unevenly loaded.
The metering system incorporates
nylon and stainless steel componentry in
areas
affected
by
fertiliser
induced
corrosion.
The output of the ground driven
metering system is controlled by a stepless
variable speed gearbox, which can easily
be adjusted. Each meter system has its
own separate adjustment. VRT equipped
seeders use individual hydraulic motors to
control metering rates.
The blower’s hydraulic system uses
quality components and will require minimal
maintenance. The system has been
designed to operate in a harsh environment.
It is fitted with a check valve to prevent
damage if incorrectly connected.
The blower is mounted on the trailer
frame and houses a high capacity impeller.
It has been specifically designed to operate
in the rough conditions that occur during
normal operation. The impeller is directly
mounted to the motor, which means that
there are no external bearings or an external
coupling.
Calibrating the ground driven metering
system has been simplified by providing a
chart with instructions to the side of the bin.
There is no need to calculate figures if
calibrating within average application rates.
A collection tray and an accurate scale
set is included with the Air Seeder.
For further information on individual
aspects of the seeder refer to the appropriate
section in this manual.
