4. ESSENTIAL SOWING CONCEPTS
4.1 TERRAIN
The better the soil condition, the better the sowing quality.
Work is more dicult on big clods or uneven furrows.
Although machines resist harsh conditions, if the seedbed
does not satisfy apropriate conditions then the sowing
quality will suer.
4.2 THE SEED
It is essential to use high-quality, clean and uniform seeds.
4.3 SEED PLANTING DEPTH
The seed planting depth has consequences for tillering,
as well as for the plant’s strength and its ability to resist
frostbite or drought. The parent shoot grows from 1 to 2 cm
under the ground, whatever the depth of the seed.
Planting deeper does not necessarily mean getting deeper
roots. Only a few roots grow from the lower part of the seed.
Most of them grow from a parent shoot close to ground level.
Normal Planting Depth: from 2 to 4 cm
Fig. 4.1Fig. 4.1
SEEDSEED
TilleringTillering
nodenode
• Thick stem, short rhizome
and resistant to frostbite.
• Multiple tillering providing
from 3 to 6 shoots and a lot
of blades, from 6 to 10.
• Deep and thick roots,
approximately 5 cm in width
and 10-12 cm in depth.
• With less grains per sowing
square metre, more ears
are obtained.
Deeper Planting: from 5 to 6 cm
Fig. 4.2Fig. 4.2
SEEDSEED
RhizomeRhizome TilleringTillering
nodenode
• Fine stem, rhizome
exposed to frostbite.
• Late and weak tillering, 1
or zero shoots and only
a few blades, 3-4 aprox.
• Medium quality roots
of approximately 3 cm
inwidth and5 cm indepth.
• More grains per sowing
square metre are required
to obtain the same
number of ears as in the
previous case.
Very deep planting: from 8 to 10 cm
Fig. 4.3Fig. 4.3
Rhizome
Seed
Tillering
node
• Very ne stem. No tillering
and only one blade.
• Seed runs out of supplies
by growing a long rhizome
which frostbite can easily
cut.
• The plant takes weak
roots, approximately 1 cm
in width and 3 cm in depth.
• Twice the number of grains
per sowing metre are
required to obtain the same
number of ears as in the
rst case.
IN VERY COLD PLACES, REPEATED FROSTBITE
CAN HAVE A HONEYCOMB EFFECT ON THE
GROUND’S MOST SUPERFICIAL LAYER. IN THIS
CASE THE PLANT’S VERY FIRST ROOTS CAN
LOOSEN AND THE PLANT WILL DIE. SLIGHTLY
DEEPER PLANTING IS RECOMMENDED
AND IF POSSIBLE, THE USE OF ROLLERS
TO COMPACT THE EARTH TO BETTER PROTECT
THE SEEDS.
WHEN STARTING THE MACHINE, FURROWS
WILL NOT CONTAIN ANY SEEDS FOR A METRE.
WHEN STOPPING THE MACHINE, SEEDS
WHICH WERE PREVIOUSLY INSIDE THE SEED
HOSES, SLIDE FROM THE MACHINE AND END
UP PILED ON THE GROUND. TAKE THIS INTO
ACCOUNT WHEN STOPPING AND STARTING
THE MACHINE IN ORDER TO ACHIEVE MORE
ACCURACY.
ALWAYS WORK AT A UNIFORM SPEED
AS SUDDEN ACCELERATING AND SLOWING
DOWN WILL CAUSE AN IRREGULAR SEEDS
DISTRIBUTION.
THE RECOMMENDED PLANTING DEPTH
VARIES DEPENDING ON THE TYPE OF CROP,
SO WE RECOMMEND THAT THE FARMER
GETS PROFESSIONAL ADVICE FROM EXPERTS
OR SPECIALISTS IN THIS AREA.

- 15 -
5. STARTING
Before working with the planter, the following points should
be taken into account:
• Check that all the components of the planter are correctly
lubricated. Grease periodically the mechanical elements.
• Check the tyre pressure.
• In the case that the planter is equipped with an automatic
transmission gearbox, check the oil level.
• Check that the ducts of the hydraulic system of the planter
are in good condition.
• Check that the ducts of the suction system are in good
condition.
• Adjust the height of the front hitch according to the tractor
being used.
• Check the tightening torque of the wheel studs.
After coupling the planter to the tractor:
• Check the planter is correctly coupled to the tractor.
• Before starting the planter, become familiar with all its
parts and adjustments.
• Start the planter when the hopper is empty in order to free
the pipes from condensation water or impurities.
• Adjust the planter and all its components to the type
of terrain to be planted on.
5.1 COUPLING TO THE TRACTOR
The ARGO planter features a ring-type hitch or ball hitch.
MAKE SURE THAT NO PERSON OR OBJECT
IS EVER BETWEEN THE PLANTER AND THE
TRACTOR WHEN COUPLING OR UNCOUPLING
BOTH MACHINES.
THESE OPERATIONS REQUIRE THE UTMOST
ATTENTION TO PREVENT PHYSICAL INJURIES
TO THE PERSON OPERATING THE MACHINE.
For the coupling maneuver, follow these steps:
1- Connect the planter's rotating ring or ball hitch to the
tractor, at the coupling point for trailers (Fig. 5.1).
2- Raise the machine's support foot.

IMPORTANT:
THE MAXIMUM FLOW RATE FOR
THE HYDRAULIC CIRCUITS WITH YELLOW AND
GREEN CAPS MUST NOT EXCEED 80 L/min.
ALWAYS PERFORM MAINTENANCE TASKS
ON THE MACHINE WITH THE HYDRAULIC
CONNECTIONS DISCONNECTED.
WHEN CLOSING OR OPENING THE FOLDABLE
PARTS AND MARKERS, MAKE SURE THAT
THERE IS NOBODY NEAR TO THE MACHINE
OR ANY FOREIGN OBJECTS IN THE PATH
OF MOVING PARTS.
IF THE MACHINE DOES NOT RESPOND WHEN
HYDRAULIC PRESSURE IS BEING DELIVERED,
CHECK THAT THE HYDRAULIC AND ELECTRICAL
CONNECTORS ARE PROPERLY CONNECTED
TO THE TRACTOR'S DISTRIBUTOR AND THAT
THE HYDRAULIC CIRCUITS' SHUT-OFF VALVES
ARE OPEN.
KEEP THE HYDRAULIC PIPES IN A GOOD
CONDITION. PRESSURISED OIL CAN PENETRATE
THE SKIN AND CAUSE VERY SERIOUS INJURIES.
THE HYDRAULIC CONNECTORS SUPPLIED
BY THE MANUFACTURER MUST BE USED.
5.4 TRANSPORT POSITION
With the machine hitched to the tractor and the hydraulic
circuits connected to it, follow these steps:
1- Check that all of the seed hoppers are closed properly
(according to model) (Fig. 5.10).
Fig. 5.10Fig. 5.10
2- Close the valve of the seed distributors (according
to model); to do this loosen the knob, turn the lever
to its lowest position and tighten the knob to fix it there.
Repeat this process for all sowing units (Fig. 5.11).
Fig. 5.11Fig. 5.11
3- Place all of the sowing unit's levers in the transport position
(in red, Fig. 5.12) (according to model).
Fig. 5.12Fig. 5.12

4- Fold up the markers (according to model). To do this,
the application must be on (APP ON).
5- Fold up the distributor heads and chassis. To do this,
the application must off (APP OFF).
IMPORTANT: MAKE SURE THAT THE
DISTRIBUTOR HEADS ARE FULLY FOLDED UP
BEFORE ROTATING AND FOLDING UP THE
CHASSIS.
6- When the chassis is folded, continue delivering
hydraulic pressure for a further 5 seconds.
IMPORTANT: BEFORE TRANSPORTING THE
MACHINE ON PUBLIC HIGHWAYS OR ROADS,
MAKE SURE THAT THE LATCHES ARE CLOSED
(FIG. 5.13).
Fig. 5.13Fig. 5.13
IMPORTANT: BEFORE TRANSPORTING THE
MACHINE ALONG ANY TYPE OF ROAD, MAKE
SURE THAT THE SERVICE BRAKES ARE IN GOOD
WORKING ORDER, BOTH ON THE TRACTOR
AND ON THE MACHINE.
IMPORTANT: BEFORE FOLDING THE
MACHINE, MAKE SURE THAT THE SOWING
UNITS ARE IN THE WORKING POSITION AND
NOT DISABLED.
5.5 FILLING AND EMPTYING THE HOPPERS
The machine has several hoppers, depending on the model
and its conguration:
PLANTER version:
· SEED HOPPERS ON THE SOWING UNITS.
· CENTRAL HOPPERS FOR MICRO-GRANULAR FERTILISER.
· CENTRAL HOPPERS FOR MICRO-GRANULAR PRODUCTS.
SEEDER version:
· CENTRAL HOPPERS FOR SEEDS and/or MICRO-GRANULAR
FERTILISER.
· CENTRAL HOPPERS FOR MICRO-GRANULAR PRODUCTS.
In order to safely and quickly ll the hoppers, the best way
is using a WORM DRIVE. A hydraulic crane can also be used
to raise the BIG BAG above the hopper in order to ll it. Check
that the whole bag volume ts into the hopper. To secure
the BIG BAG to the crane, follow the instructions provided
by the its manufacturer.
IMPORTANT: BEFORE FILLING THE HOPPERS,
FIRST CHECK THAT NO FOREIGN OBJECTS
HAVE BEEN LEFT INSIDE.
IMPORTANT: BEFORE FILLING THE HOPPER,
MAKE SURE THAT THE VALVES AND DRAIN
OUTLET ARE PROPERLY CLOSED.
CHECK THAT THE PLANTER IS EMPTY, CLEAN
AND DRY.
DO NOT DEPOSIT EXTERNAL ELEMENTS INSIDE
THE HOPPERS. BEFORE FILLING IT CHECK THAT
IT CONTAINS NO OBJECT AND THE PRODUCT
OUTLET IS NOT BLOCKED.
IMPORTANT: FOR LOADING AND EMPTYING THE
HOPPER, THE OPERATOR MUST USE APPROPRIATE
PERSONAL PROTECTIVE EQUIPMENT (PPE) (DUST
MASK, GLASSES AND GLOVES).
