8- PREPARE TO USE
The Fertilizer Planter JM 2640 PD EX makes the planting direct or
conventional.
In this phase, you should already have made the Planning of the
culture thatit willplant,and alreadyhavethe necessaryelementsto regulate
the Machine to get whatever it can to offer.
Fig01
8.1.1 - Selector
The selector has the function of just leaving one seed in each hole.
During the aspiration, several seeds stick to the same hole, as if they will
pass for it, dragged by the force of
aspiration. The action of the selector
is to eliminate the seeds in surplus,
leavingjustonethat,bythe rotation of
the disc, it is taken until the place
where ceases the aspiration, being
then liberated and through of the
conductor tube, of special format,
arrivestothesoilwithreducedspeed.
(Fig01).
8.1.2 - Distributor Body
Thedistributorbody(Fig 002)
is composed of:
a)- disc support insert.
b) - insert fixation plate.
Fig002
8.1 - Seeds Distribution
Your planter is equipped with pneumatic system of selection and
distribution of seeds by aspiration, negative pressure (vacuum). It is the
system that now equips the planters of larger precision of the world.

8.1.2.1 - Disc support insert
Thediscsupportinsert (Fig003“a”)onwhichrotatesthediscdistributor

WE RECOMMENDED TO VERIFY IT PERIODICALLY AND TO
CHANGE IT, IF NECESSARY, TO EACH 500 TO 1.000 Ha (HECTARE)/
PLANTINGROW, DEPENDING ONTHEPLACEDUSTOF THE WORK,
PERIODICCLEANING,ETC.
For the substitution of the insert, you must verify attentively for that
the fittings are positioned correctly in the lodging of the distributor's body.
Later, fix it through the disc (Fig 003 “b”) and fixation screws.

ATTENTION
Before the beginning of each season, be certified of the
good condition of the plastic screen. The ejector facilitates
the regularity in the exit of the grains. We recommended
verifying periodically the flexibility and good condition.
ATTENTION
Make cleanings daily with sponge of steel inside the
distributing box of seeds and in the planting discs.
8.1.3 - Cover of the distributor
The distributor's cover possesses a floodgate (Fig 004 " a ") that
controlsthearrivalandtheleveloftheseedsassuringa constantprovisioning
of the disc.
Depending on the used seeds, two basic positions exist for level
adjustmentoftheplate and screen in
thefloodgatethatmustbeverifiedand
used. If necessary, however,
intermediate positions will also be
able to be used.
Position 1 - HIGH POSITION,
for big seeds (maize, soybean, pea,
peanut, cotton, etc.).
Position 2 - LOW POSITION,
forsmallormediumseeds(sunflower,
sorghum, canola, tomato, small
soybean , etc.).
Theadjustmentofthefloodgate
is made through of the movement of
the level plaque after loosening the
fixation bolts. The set possesses also an assembled plastic screen under
the level plate to control the level of grains close to the disc (Fig 004 “b”).

Operator’s Manual JM 2640 EX PD
IMPORTANT
Your planter is a highly precise machine and needs an
appropriate treatment to offer you the best performance.
8.1.4 - Adjustments in the distribution
Two factors influence in the degree ofprecision of the Exactaair:
1-Thepositionoftheselector(Fig005) in relation to the holes of the
disc. It is necessary to adjust the selector according to the size of the seed
to be sowed.
2 - The aspiration potency (depression) existent to the level of the
disc. It is necessary to adapt the aspiration potency to the weight of the
seeds.The system of distribution and selection of seeds of the Exacta air,
allows an only adjustment of:
- position of the selector in relation to the size of the seed;
- adaptation of the aspiration to the weight of the seeds.
Theadjustmentleverpositioned in the direction of the sign (+) in the
scale moves the selector away from the holes of the disc, increasing the
aspiration, closing the entrance of air, what provokes a tendency to the
doubleones.
The adjustment lever positioned in the direction of the sign (-) in the
scale approximates the selector to the holes of the discs. And it reduces
the aspiration, opening the entrance of air that provokes a tendency to the
flaws.
Fig 005 ATTENTION
These positions are for speed in the PTO of 540 rpm,
except for the great seeds, where a speed lightly superior to
540 rpm can be necessary.
The positions above are only indicative, the initials
controls and accompaniment during the planting are
indispensable.
Positions suggested in the index 1:

8.1.5 - Change of the discs for seed.
For the assembly or substitution of the distributing discs of seeds,
unfastened the wing nuts, remove the cover with visor and the selector of
seeds. Remove the disc that is in the set and place the wanted disc (Fig
006),beingobservedthe correct side.To setup,makethesameoperations
above,butintheinversesense
ATTENTION
For each seed type will be necessary to use the disc with
the number of holes and appropriate diameter (check list of
discs)
Before placing the machine in operation, be certified that
the distribution boxes are equipped with the convenient seed
discs and perfectly regulated.
The selector of seeds is placed on the disc.
The seeds should be treated in agreement with the
instructions of the supplier of the product. After the treatment
they should be droughts in the shade, and only after the
complete dry they should be used for the planting.
We recommended using lead together with the seed, and
or industrial talc when there is a lot of humidity in the air.

ATENTION
So that the cut disc makes a perfect work, it is necessary
to always maintain it sharp.
For that, use the action of a file to sharp the disc.As sharp best the
disk, better is the cut of the disc.

8.4 -Adjustment of depth of fertilizer placement and seed.
Your Exacta JM2640 possesses the following active elements:
-Cutting disc is destined to cut the strawand to do the first cut in the
soil, facilitating the work of the double disc of the fertilizer.
-Doubledisc (Fig010)isdestined to openthefurrowfor depositionof
thefertilizer.
-Inalternative,thedepth furrower is destined “to open” thebottomof
thefurrow, allowing an easier penetration of the rootsandtheplacementof

recommendation.
Coupled double disc in pivot system, destined to the opening of the
furrowfordepositionofthe seed.
As these systems are in
certaininterlinkedway, thereisneed
oftheyberegulatedinwaythatthey
could carry out its function, without

what would harm the acting of the
machine.
A practical way of getting a
goodadjustmentisthefollowing:
With the machine with
stockingfertilizerloadandseedand
coupledtothetractorwithwhichwill
go towork,gototheplantingplace.
1) Lower the machine driving
thecommandofthetractorandbeing
certified that the hydraulic system
wascompletelydrove.
2)Loosenthe tighter thatgive
pressuretothespringsofthefertilizer
doubledisc(orfurrower)and loosen
the ones of the seed double disc.
3) Move forward with the
tractor some meters in reduced
speed and you will already have an
idea of the behavior of the machine
relatively to the situation of your
farming(typeandstateofthestraw,
hardness of the soil, etc).

of the fertilizer double disc and go advancing some
meters,observing theperformanceofthemachine - cut
of the straw, cut of the soil, opening of the furrow and
depthofdeposition offertilizer. If necessary,increasethe
pressure of the springs in the rod.
However, do not place more pressure than the
necessary. If youareworkingwith deepfurrower, you will
verifythatthepenetrationisveryeasy,almostindependent
of the action of the spring.
5)After having regulated the fertilizerdoubledisc.
Regulate the pressure of the springs of the seed

the superior tighter (Fig011 “a”) to allow the rod to go
downthenecessary.
6) After, regulate the depth limit wheels (Fig012
“a”) and verify, opening the furrow in the soil, the real
depththatwasthe fertilizer andtheseed.Thedepth limit
wheels should work with plenty pressure on the soil, in
order to they could follow the contours of the soil and to
place the seeds to the same depth and like this
guaranteeingauniformgrowing of the plants.
At.: If you give too much pressure to the springs,
you take the risk of the machine to be lifted up for the
reaction of the soil to the penetration, increased by the
potency of the springs.
The capacity of
penetration of the machine is
gotten through the appropriate
and conjugated pressure of the
