6.5 SEED FLOW PRE-TESTING
Once the seed dosage is adjusted (see section 6.4 SEED DO-
SAGE ADJUSTMENT), a flow test must be carried out to verify
that the dose to be sowed is the same as the one indicated
in the dosage charts.
FOR PERFORMING THIS PROCEDURE, IT IS NE-
CESSARY THAT THE ENGINE IS OFF AND THE
STARTING KEY IS OFF THE IGNITION CONTACT.
PARA REALIZAR ESTA TAREA, ES IMPRESCINDI-
BLE PARAR EL MOTOR DEL TRACTOR Y SACAR
LA LLAVE DEL CONTACTO DE ARRANQUE.
EN MODELOS DE MÁQUINA CON DOBLE DO-
SIFICADOR DE SEMILLA, SE DEBERÁ REGULAR
AMBOS DOSIFICADORES POR IGUAL Y REALI-
ZAR EL ENSAYO DE CAUDAL EN AMBOS.
RESPECTO LAS DOSIS A DISTRIBUIR DE ABO-
NOS CONVENCIONALES O MICROGRANU-
LADOS E INSECTICIDAS, SE RECOMIENDA AL
AGRICULTOR ASESORARMIENTO PROFESIO-
NAL MEDIANTE TÉCNICOS O ESPECIALISTAS
EN DICHA MATERIA. ANTES DE EMPEZAR A
TRABAJAR, SE DEBERÁ REALIZAR UNA PRUEBA
DE CAUDAL PARA COMPROBAR QUE LA DOSIS
A DISTRIBUIR SEA LA DESEADA.
IF THE SEED HAS EXCESSIVE TREATMENT
DUSTS, THE FLOW MAY DECREASE; THEREFO-
RE, IT IS ADVISABLE TO PERFORM A SECOND
CHECK CONTROL AFTER HAVING DISTRIBUTED
APPROXIMATELY THE CONTENT OF THREE HO-
PPERS.
6.5.1
MODELS WITH MECHANICAL TRANSMISSION
A series of previous steps must be performed for carrying
out the test:
1-
Couple the machine to the tractor in a slightly raised posi-
tion (the sowing equipment does not touch the ground).
2-
Fill the product hoppers or partitions.
3-
Open the cover of the Venturi injector using the two
quick-release fasteners and move the calibration control
to the test position, “
NO
” (Fig. 6.36).
4-
Place the supplied bag or a container underneath the
Venturi injector exit (Fig. 6.37).

5-
Adjust the dispensers’ settings.
ALL THE DISPENSERS MUST BE IN THE TEST PO-
SITION WHEN PERFORMING THE CALIBRATION
TEST. OTHERWISE, PRODUCT WILL ACCUMULA-
TE IN CERTAIN LOCATIONS AND MAY CLOG THE
COMPRESSED AIR SYSTEM.
FOR MODELS WITH TWO DISPENSERS, THE CA-
LIBRATION TEST MUST BE PERFORMED IN BOTH
DISPENSERS AT THE SAME TIME.
IF THE MACHINE HAS THE CONVENTIONAL OR
MICROGRANULATE FERTILIZER KIT, BOTH PIPES
OF THE MICRO AND/OR FERTILIZER KIT MUST
BE DISCONNECTED FROM THE COLLECTION
BOXES IN ORDER TO PERFORM THE CALIBRA-
TION TEST (Fig. 6.38) AND THE PIPE MUST BE
POINTED TOWARD A BAG OR CONTAINER.
