TECHNICAL CHARACTERISTICS
3.4 USE ACCORDING TO DESIGN
The Seed Drill SM-1909/L has been designed for normal use in agricultural work, especially cereal and
other kind of grain seeds.
If the machine is used in circumstances other than the above, the manufacturer will not be held respon-
sible for any damage caused.
The user must observe all regulations concerning safety, trac and hygiene.
If the machine is modied by the user, the manufacturer’s warranty is cancelled. LAMUSA will not be
held responsible for any damage caused.
3.5 GENERAL SAFETY INSTRUCTIONS
Before starting the machine, please check the machine is in good condition for work and is safe for road use.
In thoroughfare, please observe trac signs and regulations.
It is forbidden to ride on the machine or climb into the machine when it is running.
Before using the machine, the user must be familiar with all operating elements.
Please be extremely careful when coupling and uncoupling the machine to the tractor.
Please check that the PTO shaft is in good condition and well protected.
Prevent the protective tube from turning by holding both the tube and chain provided for this purpose.
Mount the PTO shaft’s transmission only when the tractor’s engine is o.
Before connecting the PTO shaft, be sure that the danger zone surrounding the machine is clear.
Never leave the tractor’s driver’s seat while the machine is in operation.
Do not deposit external elements inside the hopper.
When mantaining the hydraulic system of the seed drill, make sure that it is depressurised and the
tractor’s engine is o.
Please regularly check the condition of the tubes and hosepipes in the hydraulic system. These parts
age naturally and their life should not surpass six years. Please replace when necessary.
When raising the seed drill, the front axle is unloaded. Ensure that the machine has enough load to
prevent it overturning. At this time you must ensure that the condition of both the steering and the
brakes is optimal.
During transit with the raised seed drill, block the lowering switch. Before leaving the tractor, lower the
seed drill onto the ground and remove the tractor’s starting key.
Always use enough supporting elements when maintaining the machine in a raised position to prevent
the machine from lowering or falling.

TECHNICAL CHARACTERISTICS
3.6 LOADING AND UNLOADING INSTRUCTIONS
Use a bridge crane to load and unload the truck. A specically designed hook, as shown in gure 1,
should be used to prevent damage caused by the weight of the machine itself. Tow ropes should be
fastened to the machine’s tripod as well as to the fasten points situated in the tine coulters’ chassis.

ESSENTIAL SOWING CONCEPTS
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 une-
ven furrows.
Although LAMUSA machines resist harsh conditions, if the seedbed does not satisfy appropriate condi-
tions then the sowing quality will suer.
4.2 THE SEED
It is essential that seeds are well maintained and clean. Barley seeds should be trimmed.
4.3 SEED PLANTING DEPTH
The recommended seed planting depths are from three to ve centimetres. Planting too deep causes
problems as rhizome cannot reach the surface and the plant will die. It does not matter that some grains
are visible because the harrow’s tines will cover them eventually.
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.
Thick stem, short rhizome, 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.
Fine stem, rhizome exposed to frost-
bite.
Late and weak tillering, 1 or zero
shoots and only a few blades, 3-4
aprox.
Medium quality roots of approxima-
tely 3 cm in width and 5 cm in depth
More grains per sowing square metre
are required to obtain the same num-
ber of ears as in the previous case.
Very deep planting: from 8 to 10 cm.
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, appro-
ximately 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.

9
ESSENTIAL SOWING CONCEPTS
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 RO
LLERS TO COMPACT THE EARTH TO BETTER PROTECT THE SEEDS.
IN ALL LAMUSA MACHINES, THE RIGHT SIDE WHEEL ACTIVATES THE SEED DISTRIBUTOR’S MECHANI
CAL TRANSMISSION. CONSEQUENTLY, SHARP CURVES SHOULD BE PERFORMED TOWARDS THE LEFT
SIDE, SINCE USING THE GROUND WHEEL DRIVE WOULD CAUSE A LESSER SEED DISTRIBUTION.
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 CAU
SE AN IRREGULAR SEED DISTRIBUTION.

5. STARTING
5.1 COUPLING THE SEED DRILL
Seed drill SM-1909/L is supplied with a three-point linkage
of category 3.
Fig. 5
Fig. 6
BE ESPECIALLY CAREFUL DURING COUPLING
AND UNCOUPLING THE MACHINE.
Once the seed drill is coupled with the tractor, the PTO shaft
should be adapted. First dismount and insert one end into
the tractor’s universal joint shaft and the other end into the
seed drill. Look for the minimal movement length “L” (g. 6)
by raising and lowering the hydraulic lift.
Cut the spare plastic and metal into parts of the same length
and remount the PTO shaft.
Operate the hydraulic lift and check that the PTO shaft’s mo-
vement is correct.
WHEN OPERATING THE PTO SHAFT CHECK
THAT THE ENGINE IS OFF. ALWAYS WORK WITH
THE PTO SHAFT PROTECTED AND IN GOOD
CONDITION. PREVENT THE PTO SHAFT’S TUBE
FROM TURNING BY SECURING IT WITH THE
CHAIN PROVIDED.
WHEN LOWERING THE SEED DRILL TO THE
GROUND, UNPLUG THE TRACTOR’S UNIVERSAL
JOINT SHAFT SO THAT THE PTO SHAFT DOES
NOT HAVE AN EXCESSIVE INCLINATION MAX.

WHEN HOLDING THE TRACTOR UNIVER
SAL JOINT SHAFT’S CLUTCH IN, PERFORM IT
GENTLY. STARTING SUDDENLY COULD SE
RIOUSLY DAMAGE THE SEED DRILL.

5.4 TRANSPORT POSITION
To set up the transport position, follow these steps:
1. Folding the track markers (optional equipament).
2. Raise the machine until tine coulters are detached from
the ground.
Fig. 11
AFTER COUPLING THE MACHINE TO THE
TRACTOR, CHECK THE ROAD HOLDING IS CO
RRECT AND THE STEERING IS WORKING PRO
PERLY.
PREVENT THE MOBILE ELEMENTS FROM MO
VING.
3. Raise folding parts and check that the hydraulic safety
trigger (g. 12) is correctly fastened. This will prevent the
folding parts from falling during transit.
4. Place the 2 side rollers’ bolts (g. 13) in the holes to block
their movement.

5.5 HYDRAULIC SYSTEM
FLOW REGULATORS
To smoothly hydraulically fold and unfold the seed drill, the-
re are two ow regulators (g. 14) that perform both actions
respectively. They should be adjusted depending on the
hydraulic ow supplied by the tractor. Starting with an al-
most completely closed ow regulator is recommended to
prevent folding too fast, which could damage the seed drill.
Fig. 14
NEVER STAND UNDER THE MACHINE’S EXTEN
SION ARMS OR IN THEIR SWIVEL AREA.
The machine is also provided with hydraulic safety triggers
to secure the folding parts during transit. The gure shows
the trigger in the safety position.
BEFORE UNFOLDING THE FOLDING PARTS TO
START WORK, AS WELL AS AFTER PRESSURI
SING THE SYSTEM, MAKE SURE THE TRIGGERS
HAVE BEEN UNFASTENED.

6.3 PREVIOUS FLOW TEST
YOU MUST TURN THE WHEEL UNIFORMLY
USING THE CRANK AT APPROXIMATELY ONE
REVOLUTION PER SECOND, DEPENDING ON
THE LAND’S CHARACTERISTICS, TYRE’S MA
NUFACTURER OR TYRE PRESSURE. IT IS HIGHLY
RECOMMENDED TO PERFORM A FIELD TEST
AS DESCRIBED IN THIS MANUAL.
IT IS DANGEROUS TO TURN THE WHEEL WITH
YOUR HANDS AS THE MUD SCRAPER CAN
CAUSE INJURIES.
Accurately weigh the collected seeds.
At a selected opening, you can obtain the kilograms per hec-
tare distributed by the machine, by multiplying the weight
by 40.
For ease of performing these operations the machine should
be coupled to the tractor in a slightly elevated position (whe-
els should not be in contact with the ground). It is also neces-
sary that the hopper is only half-lled with seeds to alleviate
diculty in turning the wheel with the crank.
If seeds show excess treatment powder, ow can be redu-
ced, consequently a second control is recommended after
sowing approximately three hoppers.
TO PERFORM THE PREVIOUS FLOW TEST IT IS
ESSENTIAL THAT THE MACHINE, THE TRACTOR
AND THE UNIVERSAL JOINT SHAFT ARE ALL
SWITCHED OFF.

15
DOSAGE
Close the trap-door (g. 21/5).
Open the hopper’s folding cover (g. 21) and ll the hopper
with seeds.
Open the lower trap-door (g. 21/7).

WHEN YOU END THE TEST, CLOSE THE COVER OF
VENTURI INJECTOR, MOVE HANDLE IN POSITION
“OK” AND LOCK IT.
6.4 COMPLEMENTARY DOSING TESTS
1- Test to determine the number of wheel turns.
If dierences exist between the test and the actual dose dis-
tribution (due to a very uneven or light soil, low pressurised
tyres, etc.), an experimental test can be performed.
First of all, the distance (in metres) as shown in the table
below should be marked on the eld’s ground using a tape
measure:
WORKING WIDTH METRES TO COVER
SM 400 62,5
SM 450 55,6
SM 500 50,0
SM 600 41,7
Next, the seed drill in working position should cover that dis-
tance.
By means of a mark made previously on the tyre, count the
number of turns performed in the covered distance. A good
place whereby which to count could be the wheel’s mud
scraper.
By following these steps we can obtain the actual number of
turns performed in the seed dosing test. By performing the
test, we will know the actual kilograms per hectare distribu-
ted by the machine.
Fig. 22
2- Seed dosing adjustments.
When using high quality certied seeds it is not enough to
know the weight in kilograms distributed by the machine, as
the nal result of the harvest will depend on the number of
plants which eventually ripen.

16
DOSAGE
Every plant requires a certain amount of land from which nutrients will be absorbed. Therefore, both
a low or an excessive plant density can be detrimental. To determine how many kilograms per hectare
are to be sown, you should know the number of plants per square metre that are going to be planted.
As a guidance, the recommended number of plants per square metre when sowing wheat or barley in
un-irrigated land can be found in following table :
Please note that in spring there is less tillering so more seeds should be sown.
LAMUSA AGROINDUSTRIAL S.L. RECOMMENDS THAT THE FARMER SEEKS PROFESSIONAL ADVICE
ABOUT THIS SUBJECT FROM A TECHNICAL SOWING CENTRE
SEED DOSING SHOULD BE ADJUSTED TO EACH TERRAIN, DEPENDING ON THE: TEXTURE, FERTILI
ZING LEVEL, PLUVIOMETER RESULTS AND SOWING SEASON, GRAIN QUALITY, GERMINATING AND
TILLERING POWER, ETC
It should be taken into account that a seed’s germinating power is variable and dependant on multiple
factors. It can be experimentally calculated to be between 70% and 80%, which is practically equivalent
to multiplying the number of grains to be sown by 1,43 or 1,25 respectively.
Next, we describe a practical method to determine the number of kilos per hectare to be distributed
once we know how many plants per square metre we want to obtain.
1- Place seeds on the “seed counter” (g. 23)
Wipe seed counter with your hand to make sure that there is only one grain per slot (100 grains in total).
Do the same 10 more times to obtain 1000 grains
2- Weigh 1000 grains with the precision scales. We call the result the OPERATIVE WEIGHT
3- Once we know how many seeds per square metre we are going to sow, we should adjust the fo-
llowing kilograms per hectare in the dosing control:
Kilograms per hectare=(grains per m2x OPERATIVE WEIGHT) / 100
AUTOMN SPRING
Premature sowing, 200 plants per m2Premature sowing, 310 plants per m2
Late sowing: 265 plants per m2Late sowing: 445 plants per m2

7. ADJUSTING SEED PLANTING DEPTH
SEED DRILL SHOULD ALWAYS WORK HORIZONTALLY, WITH BOTH THE REAR AND FRONTAL TINE
COULTERS EQUALLY PENETRATING THE LAND.
VERY IMPORTANT: THE TRACTOR’S CONTROLLER THAT MOVES THE FOLDING PARTS’ CYLINDER
MUST BE IN FLOTATION MODE, TO BETTER ADAPT TO THE GROUND.
7.1 ADJUSTING RATCHETS AND SPINDLES
There are two ratchets in the machine’s central body and two spindles in the side wheels. All of them
have an adjusting scale to indicate their position. Their adjustment positions in the respective scales
should be the same.
After adjustments, the control lever of the ratchet should be pulled back towards the inner part of the
machine.
WHEN SOWING ON TILLED OR NONCOMPACT GROUND, TAKE THE PRECAUTION OF SELECTING ONE
OR TWO POINTS LOWER IN THE ADJUSTING SCALE ON THE SIDE WHEELS IN ORDER TO AVOID SIN
KING INTO THE GROUND.
To adjust the side wheels, use the crank provided (1, g. 25).

7.2 CENTRAL RATCHET WITH SLIDE
In the upper part of the ratchets you will nd a slide along with a blocking bolt. This bolt allows, when
placed, to lean the machine’s weight on the sowing equipment and therefore put the maximum pres-
sure that direct sowing requires. When the bolt is not placed, sowing equipment stays in otation mode
to work on the tilled land.
NOTILL SOWING: THE BLOCKING BOLT IS PLACED AND THE SLIDE’S POSITION FIG. 26/1 IS FROM
THE SCALE TOWARDS THE TOP.

FROM THE SCALE TOWARDS THE BOTTOM.
7.3 HEIGHT-ADJUSTABLE TINE COULTERS
Tine coulters which are aligned with both the tractor’s wheels and the seed drill, have an adjustable
height by means of a slide with holes which allows them to be lowered up to 7 cm. This allows to com-
pensate the track mark eect and to achieve a more uniform seed planting depth. Pressure performed
by the tine coulters can be adjusted by using the nut on top of the spring (g. 27/1)
EXCESSIVE LOOSENING OF THE NUT COULD CAUSE THE SPRING TO JUMP OUT DANGEROUSLY DUE
TO PRELOADING.
