SAFETY (VRT)
The VRT seeder uses hydraulic
motors to turn the metering system. The
hydraulic motors, which are mounted on the
left hand side of each meterbox, takes
hydraulic flow from the tractor to rotate.
The motors can be operated from
the tractor or the seeder. Hydraulic flow is
supplied to the metering system whenever
the tractor’s hydraulics have been engaged
to run the fan or auger, if fitted.
It is important to disengage the tractor’s
hydraulic system and to
TURN THE
TRACTOR OFF
before attempting to work
on or around the metering system. The
metering system could be activated if
someone pushes the prime key or calibration
function from the monitor.
The hydraulic motors can also be
started from the seeder via the red/green
calibration buttons on the left hand side of
the seeder or the front face of the pod.
Movement can also occur by rotating one or
all of the large thumb knobs located on the
front face of each bank of the manifold.
Fig.V9 Manual override valve.
Protective hinged guards have been
fitted to the side of each meterbox with
warning decals. Ensure that the guards
remain in place and that the decals are
readable.
