Higher
fertiliser costs mean that farmers must ensure accurate spreading
over the total field area, including irregular shaped fields and at
angled headlands. To achieve this KRM offer two section control methods,
the field proven Standard Section Control and Dynamic
Section Control for wider spread widths.
Section
Control Standard
Section
Control Dynamic
Section control
standard is available on all KRM spreaders and recommended at working
widths up to 24m. It works by reducing the quantity of fertiliser
being applied in line with the reduced area being spread as short
work is encountered. This is done by the double shutter system (shown
above in blue), the system can be operated manually or automatically
via GPS.
This system
works on KRM machines due to the unique Double
Double overlap spread pattern.
Recommended for wider working widths, Section Control Dynamic works in 8 linear steps by simultaneously adjusting the quantity of fertiliser applied and adapting the spread from left to right of the spreader or vice versa at angled headlands or in short work. Two additional pieces (shown in red) are fitted as standard to all KRM M-line machines, then using optional Dynamic Control, this system can be operated either manually from the Calibrator Zurf or ISObus or it can be controlled automatically by GPS.
The
Graph's above are produced using actual tray test results and prove
that simply be reducing the quantity being applied the CT (coefficient
of transition) always remains low. International standards state the
CT should not exceed 25%. Using section control standard as the width
drops from 24m down to 9m the CT is always around 10% - an excellent
result.
The diagram above shows how the shape of our spread pattern changes when Section Control Dynamic is used. Toward the tapering headland, the density of the spread to the right is reduced while the spread to the left is maintained. With this system, ultimate accuracy is maintained over the total field area.
Manual Control
Standard Section
Control can be operated manually by the operator on any KRM spreader
fitted with our calibrator Icon, Totz, Zurf or ISObus.
Manual Control
Dynamic Section
Control can be operated manually by the operator on any KRM spreader
fitted with our Calibrator Zurf or Totz or ISObus.
Automatic
Control - Standard and Dynamic
Auto
Switch
Take the
guess work out of spreading with KRM's Auto Switch, this system
will turn the spreader on and off at the headland as well
as operating Standard or Dynamic Section Control automatically
in irregular shaped fields. It can also be used for guidance
and variable rate.
Simple
to install and use this system links into the existing Calibrator
and will also generate a forward speed, making it simple to
move between tractors.
NAVI App
KRM's
NAVI COM module connects into the spreaders control box and provides
a wireless connection to an android tablet. The app handles variable rate, section control, guidance and auto on/off.
All KRM
weigh cell spreaders can now be supplied ISOBUS ready. Easy
and logical operation have always been key guidelines in the
development of our electronic controllers. To continue this
strategy the ISOBUS solution displays the same easily understandable
graphical layout on the tractors terminal.
In
many cases its possible to use your own existing GPS equipment
to work with our section control systems, a guide to comparability
and system requirements can be found here.
