Safety precautions
These safety precautions are applied for all chapters in The Operating Instructions.
Safety marks
On the machine
Before the first operation, please read The Operating
Instructions.
Do not stand in reach of folding
parts of the seed drill.
Do not use mounting holes for lifting up the seed drill.

4
In these Operating Instructions
there are distinguished three different safety massages. These indications are used:
 for alleviation of work with the seed drill
! it can happen that the seed drill could be damaged!
 in case of hurt danger
Take care of safety mark to be readable and always change damaged ones. It is mostly
important for interchange of parts or construction groups during repairing works. Safety marks
are sold by your Deputy Manager.
Keep these instructions and you will prevent accidents. Give these instructions to the other
users. Stop every activity, which does not correspond with safety.
The usage according to the directions
Seed drills are constructed according to the technical condition and accepted safety technical
rules. However, it can happen that during usage of these seed drills, user or other person could
be injured. Also it can happen that the machine or any part of equipment is damaged.
Take care to keep the machine always in good technical condition and use it only for purposes
for which it was originally made. All diseases, which can break safe usage of seed drill, must
be removing at once.
The seed drill can be operated and maintained only by people perfectly able to do these
activities and works and who are familiarized with possible risks.
Original spare parts and accessories from PD Hlohovec are constructed especially for seed
drills PNEUSEJ-ACCORD. Spare parts and accessories– not delivered by us – are not
controlled and approved. The usage of no original goods can change in negative way
constructional features of your seed drill and influence safety of employees.
For damages caused by the usage of no original spare parts and accessories, there is no
acceptance of whatever responsibility from side of PD Hlohovec.
Seed drills PNEUSEJ- ACCORD are dedicated only for sowing. For damages caused by
incorrect usage PD Hlohovec takes no responsibility.
All preventive precautions from point of view of safety of work, health protection and
transport safety must be always kept.

5
By incorrect usage is also understood the infringement of The Operating Instructions or
infringement of Service requirements and requirements of producer.
Service reliability
The seed drill is possible to use only if all safety arrangements located on machine are
mounted and are functional.
Screwed connections should be controlled in regular intervals and in case of need they must
be driven.
Also a pressure in tires is needful to control regularly.
•7,50x16 8PR - 4,5 bar
•23x8,50-12 6PR - 3,5 bar
•31x15,5-15 8PR - 3,1 bar
In case that there is a disease somewhere in the seed drill, stop work and block the machine.
Disease must be removed instantly.
Responsibility for damage
Your seed drill PNEUSEJ-ACCORD is manufactured with maximal care. However, even in
correct usage there can appear some breakdowns, which can lead in to dropout that can be
caused by:
•different structure of seed and fertilizer ( size of seed, consistence, shape, treatment,
cohesion )
•clogging or clinging ( impurity, weed, wet fertilizer )
•wear of components( dozers, wedge belt)
•damage by external factors
•incorrect speed of the seed drill
•incorrect regulation of the seed drill ( incorrect maintaining, infringement of regulation
charts)
•errors in mounting or operating of electric appliance or errors in electronic system of
tractor
That’s why, before every single usage of machine, control correctness of functions and
sufficient precision of sow of your seed drill.
Compensation requirements, which are not connected directly with the seed drill, can
not be accepted. Producer does not take responsibility for diseases, which were caused
by incorrect dosing or delivery.

6
Transport safety
For transport on overland communications, take care of commonly accepted traffic
instructions. Before ride, the seed drill must be in the condition which is acceptable for
transport conditions.
Take care of transport width, mount lights, warning and protective identification. Appliance
for making field- track lines ( Drillmat III) – dismount it from the electric power.
Block folding parts by both sides, over arm, etc., in position dedicated for transport.
Take care of allowed load of axle, carrying characteristics of tires and total weights to kept
sufficient riding and braking ability. Riding features are influenced by mounted additional
appliances. The importance must be given on wide spread and internal weight of the seed drill
mostly during ride in curves.
During movement of the seed drill do not stand on stairs!
Operating safety
During detachment of the seed drill
Be careful of injury while mounting and dismounting of seed drill onto the rod of 3point
suspensor of tractor.
That’s why keep these instructions:
•block tractor to avoid any movement
•operate with 3point suspender slowly and carefully
•for the rod of 3 point suspender there is a danger of shut of attendance between tractor
and seed drill
•detach the seed drill by the help of supporting legs to determined place
For the rod of 3 point suspender there must be correspondence between category of the seed
drill and category of tractor.
While the usage of the gear box output shaft
Keep instructions for using of the universal shaft with protective equipment.
Mount universal shaft only when engine of tractor and the gear box output shaft of tractor are
switched off. Take care of rated tubular overlap in working and transport position.
Block protective tube on universal shaft to prevent rotation.
Switch the gear box output shaft on only when there is nobody within reach of danger.
RPM of the gear box output shaft of tractor must be in correspondence with rated number of
RPM of the seed drill. Angle is regulated by type of the gear box output shaft of tractor. (See

7
in The operating instructions for the gear box output shaft of tractor). Switch the gear box
output shaft off any time there is too big buckling or it is not used.
While hydraulics operating
Mount hydraulic tubes on the hydraulics of tractor only if the hydraulic appliance of tractor is
not in operation.
The hydraulic appliance is under the high pressure. All bearings, tubes and screw connections
must be controlled regularly for leakage and outside damage! While looking for leakage use
only determined means. Remove damage as quickly as possible! Escaping oil can caused
injury and fire. When there is an injury, call the doctor at once!
While operating
Before activation and putting in operation, control close area of the seed drill (children). Pay
attention to sufficient outlook.
Ride on the seed drill during work is not allowed.
Any from rated and delivered protective appliances is not allowed to remove.
In reach of markers there can not be any persons.
Maintaining
Keep instructions for completion of rated regular control and maintaining.
In maintaining, initiate hydraulic appliance into non- pressure state, switch universal shaft of
tractor off and switch off engine of the tractor. Dismount tractor from the seed drill.
Conduct maintaining only if the machine is located on the smooth and constant surface and it
is blocked against any movement or break away. Do not use parts of the seed drill during
entrance.
Before cleaning of the seed drill with water or steam pressure (high-pressure cleaning) or by
other depurators, cover all openings into which from safety or functional purposes, water,
steam or another cleaning agent are not allowed to get. These are e.g. bearings, ventilator and
electric appliances. After cleaning remove all blockages.
After cleaning control all hydraulic connections from leakage, abandonment and damage.
Found defections remove at once!
Before work with electric appliances detach them from electrical power.
During an execution of electric welding works on mounted seed drill detach cables of
generator and battery of tractor.
Rise screwed connections released during maintaining again.

Pic.1 Scheme of the seed drill
Driving wheel of the seed drill hurries out with help of chain drive chamber seeding barrel of
dozer. According to adjustment of dozer and distance moved, seed is dosed from dozer to
diffuser. An air flow made by ventilator carries and distributes seed through distributor and
seed tubes to seeding sections.
Seed drills can be used in connection with all standard tractors (according to the type of seed
drill from 50kW). Tractors must be equipped by rod of 3point suspender or detaching triangle.
For mechanical drive of ventilator there must be protection cover of gear box output shaft
1000RPM.
Driving speed of the seed drill should be from 5-12 km per hour according to the surface, type
of soil and according to rated precision of seeding amount.

9
By seed drills PNEUSEJ-ACCORD all types of seed of sizes ranging from 1 to 10 mm can
be sowed.
wheat, barley, rye, oat, corn, bean, pea, french bean, rape,
lantern, grass, yellow-vetch.
Pneumatic seed drills can be equipped by these types of seeding sections:
•suffolk seeding section ( width of sow 1-2 cm)
– for sowing into plough up soil with
little amount of plant surpluses
•disc seeding section ( width of sow 2 cm)
– for sowing into plough up soil with
bigger amount of pant surpluses
•DXD seeding section (width of sow 2 cm)
– for universal usage to sowing into plant
residues (sowing in mulching) as into
plough up soil.

Adjustment and usage of seed drill
In this chapter you will be informed of general information about using of your seed drill.
Constructional peculiarities of particular types are described in the next chapters.
Transport by public roads
!
Put on warning gables with lightening and protection appliances.
By public roads, ride there only with empty seed hopper.
Maximal transporting speed of seed drills is 10 km per hour.
All seed drills with transport width until 3 m can be transported according to traffic
instruction on public roads.
•Seed drill MT- transport in conveyer
•Seed drill MS and MSh with working width since 3 m: fold the folding beam over and
block it. Fold a harrowing frame over and block it.
•Seed drill MV: fold folding beam over and close the ball valve in connecting line.
•Fold markers over and block them.

Warning! Take care of acute edges of the seed drill during rebuilding!
Preparation before sowing
Mounting of seed drill onto tractor

During mounting of seed drill onto tractor there can not be any person between
tractor and the seed drill.
The seed drill can be mounted onto tractor in this way:
•By rod of 3 point suspender or by triangle of tractor: Seed drills M,MS,MV
•Only by triangle of tractor: Seed drills MK,MKC,MT
For using of coupling device for mounting of seed drill, mount coupling device onto tractor.
If you use for mounting of the seed drill the coupling device, at first mount the coupling
device onto tractor and then attach the coupling device onto the seed drill. Take care:

11
•That closing hook of the coupling device
must click into blocking position.
•That closing hook of the coupling device
must be blocked Pic. 2
Pic.2 blocking of the closing hook of coupling device.
During mounting of seed drill pay attention to:
•Adjust the lower con rod that the seed drill will fluctuate into sides only limited
•Mount upper con rod as high as possible to secure parallel lift of seed drill.
•Instrument triangle of seed drill must be in working position upright. For this, arrange
length of upper brace rod.

Mount the prop shaft only when the engine of tractor and gear box output shaft is
switched off.
 Keep the operating instructions for the universal shaft.
For some types of tractors – the prop shaft must be shortened. But it can not happen that
force transmission of the prop shaft will be reduced.
Adjustment of markers
Before starting of sow, it is needful to adjust the length of markers. For this adjustment keep
this scheme:
Working width + line pitch – track width of wheels
Length of markers = __________________________________________
2
The seed drill PNEUSEJ 6 MT –with 48 sows has the working width L= 600cm. The basic
line pitch is predetermined into R = 12, 5 cm.. If there is for example the front tread of tractor
S = 150 cm then
600 + 12.5 - 150
The Length of markers = ____________________ = 231.25 cm
2

12
Under the length of marker we understand distance of marker disc from outer seeding section
in working position.
Adjustment of seed depth
The depth of sow can be adjusted according to soil conditions by the pressure on the seeding
section.
By the help of a crank- handle (Pic.3) you can change the pressure on the sowing dot centrally
among all the bearer of seeding sections.
You can change also the pressure on the sowing section individually on the particular seeding
sections. It is possible by rebuilding of springs by the help of chain elements Pic.4.
Approximate charging of seeding sections for different lengths of chain is displayed on Pic.5
In case of sowing into the light soil, narrow separation and high speed, it is not suitable to
adjust too high pressure onto the front seeding sections, because these lines will be comprised
by back seeding sections.
Pic.3 Pic.4

Pic.5 diagram of pressure onto the seeding section
Adjustment of seed amount
Attributes given into the regulating chart are only informative, because specific weight and
size of seeds are often different. Correctly adjusted attribute can be achieved by the sowing
examination. The measuring amount (for the same seed and type) will be then always
constantly delivered.
!
For seed drills with two dozers, every dozer must deliver the required seeding
amount (kg/ha). Mechanical counter of hectares shows the half surface of the width
of the machine.
For the sowing of small seeding amount, use micro dosing system, see the regulating chart 1.
An activation of this micro dosing system is described on page 16.

Adjust seed drills only in lowered and blocked position. Tractor and gear box
output shaft of tractor must be dismounted.

•Rise adjustment by 10 % more into 66
• The second sowing exam =21 kg
Pic.7 Calibration of the seed drill
Adjustment of micro – dosing system
By micro – dosing system the soft seed and small amounts for hectare can be sowed. The
advantage of micro – dosing system against the normal system for the soft seed is that for the
same sow amount the width of cells is double. By this, self-cleaning effect of cells is
increasing.
Pull the red gear wheel out to click into the position A, Pic. 8. Micro – dosing system is
working. Adjustment value must be counted down from the regulating chart for the soft seed


Mechanical counter of hectares for micro – dosing system shows overall area, which
was sowed; for seed drills with two dozers it shows half sowed area.
Control of the seed drill
Before you take your seed drill to the field, you should control these things:
•rated (standard) transport position and identification of the seed drill by warning
boards and lightening
•mounting of the seed drill onto the tractor
•mounting of bend to the diffuser
•adjustment of field - tracked lines
•opening and closing of by – passing clappers
•seeding amount of all seeding sections:
1. fill the hopper by small amount of seed when tractor is switched off
2. when seed drills with mechanical dosing are dismounted, because of safety
precautions, act according to this way:
olift the seed combination up when drive of ventilator is switched
off until the riding wheel won’t touch the ground
oturn the driving wheel approx. per 1/2 rotation more, trough which
you get little amount of seed into the bend
oturn ventilator on, let it run for a while and then turn it off
ocheck weather every seeding section blew seed out
•required adjustment of red switch point of dozer and throttle valve of fan
•turning on and off of micro – dosing system
•divider cover of distributor
•mounting of drive shaft
•closing of discharging clapper
•sieve in hopper
!
Reach the machine only when the engine and the ignition are switched off, the brake
is turbid and when all moving parts are at rest. It is forbidden to descend from tractor
when motor runs.

18
Operating during sowing
Setting of the seed drill according to field conditions
The seed drill required for sowing must be rebuilt from transport position into the working
position.
If the seed drill is not mounted onto the tractor yet, mount it.
Before dismounting of the seed drill do this:
•The seed drill MT see page 23
•The seed drill with hydraulic folding beam: fold the beam up to the working
position
•The seed drill M with manually folding beam:
ofold and screw lateral parts again
opull the lever under the beam of seeding sections up until clutch click into two
sectional tubes, see Pic.10
1 lever
2 blocking screw
Pic.10 manually folding beam
Dismount the seed drill and do these operations:
1. Dismount lightening boards and detach them from electrical power
2. Mount gear box output shaft
3. Lock – off the markers
!
Do not stand under the raised markers.
4. Fill by the seed.
!
For entrance to the hopper use only appropriate stairs

Practical advices:
Is there any foreign material in the hopper?
Is the discharging valve closed? Is there any water in bend?

19
5. Adjust the track tillers.
6. Bring the driving wheel for type MK into the working position.
7. Adjust the mechanical counter of hectares into 0
8. On harrowing frame - adjust an inclination and depth of harrowing
9. Connect an electric circuit
10. Connect field-tracked lines Drillmat III.
Operating with markers
Markers with simple operating
In transport position markers are secured by pins, which are before work locked-off and
markers must be manually tipped into lower position. Markers are controlled from cabin of
tractor by the help of lever of hydraulics, by which the pressure of oil is controlled. This oil is
carried into direct fluid motor in tipping mechanism .Rising of the oil pressure causes an
erection of both markers and falling of the oil pressure causes that one marker drops into
working position. If you want to get the same with the second marker, repeat the previous
steps (rising of the oil pressure – rising of both markers, falling of the oil pressure – falling of
the second marker).
Markers with hydraulic switching by the help of distributive air hose valve
!
During transport on public roads it is always needful to have markers fixed in
the transport position.
Markers are controlled from cabin of the tractor. In the transport position are blocked by pins,
which lock – off before work on field. Control of markers is realized by the electric button
located on the cable that leads to the distributive air hose valve/ pre – set for right or left
marker/ and by lever of hydraulics. By it you drop the chosen marker into the working
position or lift it up into the transport position.
Markers controlled by AK valve.
In the transport position are the markers mechanically blocked, whereby before putting into
working position is necessary to lock-off them.
Control of type MV, MS, MSh – lift of markers is provided by oil inlet to hydraulic circle of
seed drill, the direction of flow is from the tractor to seed drill. By activation of one marker is
necessary to loosen the oil inlet from the tractor and after that the tension spring provides the
folding of marker.
Control of type M, MK, MT – lift of markers is provided by oil inlet to hydraulic circle of
seed drill, the direction of flow is from the tractor to branch of seed drill, where is placed the
AK valve. By activation of one marker is necessary to change the direction of oil flow.
By activation of both markers into working position is necessary to open the ball valve
placed by AK valve, put the marker into working position and again close the ball valve.

20
For the adjusting of marker working speed serves the throttle valve of oil flow. By type MV,
M, MK, MT is the throttle valve bi-directional, it means, that by this valve is adjusted as lift
so also down of markeres. By type MS and MSh is the throttle valve one-way, it means, that
by this valve is regulated the speed of markers lifting. The speed of markers lowering is
adjusted by brass screen with a hole ø 1mm, which is placed before AK valve.

Hydraulic control of markers is tested by producer on hydraulic aggregate. Hydraulic
circle is filled with the oil SHELL DONAX TD.
Control of seeding amount
Errorless seeding amount is based mostly on your control. Control the seed after several
meters of ride, for bigger areas and also during work.
1. Aren’t the seeding hoses deflected?
2. Are the depth of sow and the comprehension of seed sufficient enough? Adjust the
front and back array of seeding sections.
3. Do the seeding sections sow regulated amount?
4. Does the seed run through by – passing clappers without difficulties?
5. Aren’t the seeding sections blocked?
6. Do the plant residues not limit the seeding sections?
7. Are the markers and the grubbers of feet adjusted correctly?
8. Do all by – passing clappers switch correctly?
9. Are the rotations of shaft during sowing constant?
10. Does the driving wheel rotate composedly and regularly?

If you stop on field because of congestion or disease:
∗Block the creating of field tracked lines by the button : Start/ Stop
∗Lift the seed drill up
∗Go approx. 1 m back
Adaptation of working speed – keeping of shaft rotations
Possible working speed is from 5 to 12 km per hour and depends on a type of soil and on
preparation before sowing. For heavy soil conditions ride more slowly. For light soils and in
high working speed the front seeding lines are too lapped by back seeding sections. Loosen
chains up in the front array of seeding sections and lessen the working speed.
Keep rotation of gear box output shaft of tractor. Precision of seed distribution can change, if
the rotation falls under minimal limit. For bigger seeding amounts there can happen that tubes
will be plugged.
