CAUTION
Risk of damage to the machine (version with
twin hopper)
¾
When folding the machine monitor the au-
tomatic folding of the steps (1) and the plat-
form (2) before the wings fold.
¾
Always access the platforms via the stairs
or step.
Single hopper
The single hopper is closed with a covering.
¾
Always keep the covering closed to protect
the seed against contamination, dust and
moisture.
In case of extreme development of dust, this
dust can deposit in the hopper and fill up the
roller flutes. This causes metering errors and
unnecessary wear inside the metering unit.
Twin hopper
Various options for sowing are available with
the twin hoppers:
•
Same type of fruit in both hoppers
•
Seed and fertiliser each in a separate hopper
( Grain & Fertilizer)
Both metering quantities are merged before
the distributor tower and placed together.
The twin hopper has a volume ratio of 40 : 60
(front : rear).
It is designed as pressurized hopper and must
always be closed and tightly sealed before seed
placement.
Leaks with a loss of air will cause sowing faults.
The placing quantity will drop, possibly all the
way down to zero.
¾
Check the hoppers for leaktightness after
each opening and after extended idle times
while the fan is running.
Switch on the fan and feel with your hands
around the lid or listen for escaping air.
¾
In case of leaks replace the seals or readjust
hinges and locks.
¾
Open the hoppers only after the internal pres-
sure in the hopper has been relieved.
If twin hoppers are used to transport fertiliser
over longer or bumpy distances, the fertiliser
may solidify inside the hopper.
This may cause heavy starting of the metering
unit coupled with the risk of seed bridging in
the hopper.
¾
Restore the pouring capability of the fertiliser
in this case before placing.
Seed hopper
The fan air flow is divided before the metering
units (a).
The metering units transport the seed via the
dual fall sluice into both hoses (b).
