2Intended use
The subsoiler is an agricultural machine designed for loosening and aerating soil at
a depth of up to 60 cm in order to improve its physical and biological properties.
Aeration and irrigation of the lower soil layers obtained thanks to subsoiling ensures an
excellent agrotechnical effect, positively affects the development of plants which have
a deeper root system. Subsoiling is performed in a given field once every few years -

8
most often (4-5 years).
A signal that may indicate the need for subsoiling may be water pool in the spring. After
subsoiling, there is no need to perform deep plowing, and one can sow plants by using
fruiting tools. The MGX subsoiler used immediately before the fruiting treatments has a
positive effect on the soil structure and improves the conditions for the development of
root crops.
CAUTION! The MGX subsoiler is designed exclusively for soil cultivation.
Using it for other purposes will be understood as misuse and will result in
the loss of warranty.
CAUTION! Failure to observe the recommendations of this manual will also
be understood as misuse. The manufacturer is not liable for damage caused
by misuse.
3General safety rules
The MGX subsoiler may be started, operated and repaired only by persons familiar
with its operation and the cooperating tractor as well as with the principles of safe
operation and maintenance of the unit. The manufacturer is not responsible for arbitrary
changes in the construction of the subsoiler. During the warranty period, only MANDAM
factory replacement parts should be used.
The MGX subsoiler should be operated with all precautions, in particular:
•before each start-up, check the machine and the tractor, whether their condition
guarantees safety while in motion and during work,
•it is forbidden to use the machine by persons under the age of 16, the sick, and
those who have consumed alcohol or other intoxicants,

user is responsible for damages resulting from failure to comply with these
rules.
3.1 Coupling and uncoupling from the tractor
•Coupling the machine with the tractor should be done in accordance with the
recommendations, ensuring to secure the suspension pins with cotter pins.
•When coupling the tractor with the subsoiler, it is forbidden to stay between the
machine and the tractor at that time.
•The tractor cooperating with the set must be fully functional. It is forbidden to
couple the machine with a tractor with a faulty hydraulic system.
•Remember to maintain the following: balance of the tractor with the attached
unit, its steerability and braking ability –the front axle load must not fall below
20% of the tractor’s total axle load –a set of front weights.
•In the resting position, the machine disconnected from the tractor should
maintain stable balance.
3.2 Tires
•Tire pressure must not exceed the manufacturer’s recommended pressure; it is
also forbidden to transport with too low of a pressure, which may cause an
accident or damage the machine while on large unevenness and driving too fast.
•Significantly damaged tires (especially profile damage) must be replaced
immediately
•When changing tires, secure the machine against rolling.
•Repair work on wheels or tires should be performed by persons trained and
authorized for this purpose. These works should be performed with the use of
appropriately selected tools.
•Each time the wheels are mounted, check the tightness of the nuts after driving
50 km.
3.3 Safety related to transport on public roads
When transporting the machine on public roads, it is mandatory to use a lighting
device, marking plate and side reflectors.
Do not exceed the driving speed during transport, which is:
–on roads with a smooth surface (asphalt) up to 25 km/h,
–on field or paved roads 6-10 km/h,
–on bumpy roads no more than 5 km/h.
Driving speed must be adjusted to the quality of the road and its conditions, so that the
unit does not jump on the tractor’s suspension system. Be especially careful when
passing, overtaking and turning. The permissible operating width of the machine on
public roads is 3.0 m. It is forbidden to transport the unit in which the slope inclination
previous to the unit exceeds 7º.
During transport, the clearance under the machine should be at least 30 cm

10
WARNING! Failure to comply with the above rules may pose a threat to the
operator and bystanders as well as may lead to damaging the machine. The
user is responsible for damages resulting from failure to comply with these
rules.
Pursuant to road safety regulations (Regulation of the Minister of Infrastructure of
31.12.2002, Journal of Laws No. 32 of 2002, item 262) –the unit consisting of a farm
tractor and an agricultural machine coupled with it must meet the requirements
identical to those of the tractor.
CAUTION! The unit as a part of the vehicle protruding beyond the rear side
outline of the tractor, covering the rear lights of the tractor, poses a threat
to other vehicles on the road. It is forbidden to travel on public roads
without appropriate markings.
The units should have:
- triangular plate distinguishing slow-moving vehicles,
- two front-facing boards with a white side lamp and a white reflector,
- two rear-facing boards with combined light and red reflector. The boards should be
painted with diagonal white and red stripes.
After attaching the boards, connect the electrical wires of the light and warning device
to the socket of the tractor’s electrical system.
The manufacturer does not provide the machine with warning signs as standard. Warning
signs are commercially available. Warning signs should be securely mounted in holders
and the plug should be connected to the socket of the tractor’s electrical system. Before
transport, check the operation of the lights.
After lifting the machine, check the clearance under the lowest operating
elements, which should be at least 30 cm.
3.4 Description of the residual risk
MANDAM sp. z o. o. makes every effort to eliminate the risk of an accident.
However, there is a residual risk that may result in an accident. The greatest danger
occurs in case of:
•use of the machine for purposes other than those described in the manual,
•use of the machine by minors without permission, the sick and those who have
drunk alcohol or used other intoxicants,
•presence of people and animals within the operating range of the machine,
•failure to exercise caution during transport and maneuvering the tractor,
•staying on the machine or between the machine and the tractor when the engine
is running,
•operation without observing the operating instructions,
•moving on public roads.
3.5 Assessment of the residual risk
Residual risks can be reduced by following the recommendations presented below:
•careful and unhurried operation of the machine,

11
•careful reading of the operating manual,
•keeping a safe distance from dangerous zones,
•prohibition on staying on the machine and in the machine operating zones when
the tractor engine is running,
•performing maintenance works in accordance with safety rules,
•using protective clothes, and in the case of work under the machine also a
helmet,
•protecting against access to machines by unauthorized persons, especially
children.
4Handling and Usage Information
The subsoiler is usually delivered to the customer ready for operation,
however, before starting work, the technical condition of the unit should be checked,
especially the condition of the operating elements and screw connections. During the
inspection, the subsoiler should be secured against tipping over with properly set
support legs (they are standard equipment of the subsoiler). Loose screw connections
must be tightened.
During the operation of the machine, the following may be adjusted:
- operating depth of tines –by changing the position of the supporting roller in the
adjustment handles.
- spacing of operating tines of the subsoiler.
If a subsoiler with supporting roller is purchased, its subassemblies must be
assembled during the first preparation of the unit for work. To this end, set the subsoiler
on a flat hardened ground, in a place that allows the roller to maneuver. First of all,
mount the tightened holder of the roller arms in the right place. To transport the roller,
use a lifting device with a lifting capacity of at least 500 kg due to stability during
transport. Set the arms in the subsoiler holders and connect the arms with the roller
clamp with screws (fig. 2).
Fig. 2 Connection of the arms with the roller clamp.

12
Before starting work, the technical condition of the subsoiler should be checked,
especially the condition of the operating elements and screw connections.
CAUTION! The correct procedure for assembling the rollers in the arm
holders requires the screw to be evenly tightened diagonally so that the
entire plane of the arm holders is adjacent to the plane of the roller
clamp profile. This is the most reliable way to connect the roller arms to
the machine!
The subsoiler also has adjustable spacing of operating tines. It allows to adjust
the width of the field subsoiling. The adjustment is made by loosening the M20 screws in
the tine holder, and then moving the tine along the frame profile to the desired position.
After setting all the tines, the loosened screws of the tine holder must be tightened
again.

WARNING! Operating the subsoiler on excessively moist soil is unacceptable.
Operating on stony soil with large stones is unacceptable!
Optionally, it is possible to mount a weight with a chain behind the
subsoiler’s tine (fig. 4), whose main task is to create a groove (drainage) at the
operating depth of the machine, which ensures the circulation of water moving after
rainfall.

4.2 Coupling the subsoiler with the tractor
The tire pressure of the tractor wheels should be compliant with the
manufacturer’s recommendations. The lower links of the three-point suspension system
should be at the same height, in the spacing corresponding to the spacing of the lower
suspension points. When coupling the machine to the tractor, the unit must stand on a
hard and even surface.
Fig. 6 Three-point suspension system of the tractor: 1,2 –lower rods, 3 –upper link, 4 –left hanger, 5 –
right hanger with adjustable length, 6 –lifting arm, 7 –lifting roller

15
When attaching the MGX subsoiler to the tractor, perform the following actions:
•switch the tractor’s hydraulic system to position regulation,
•remove the lower coupling pins if the tractor’s three-point suspension system is
not equipped with coupling hooks,
•carefully reverse, hang the machine on the lower links, then secure,
•connect the upper link of the tractor (in units not equipped with a trolley) –
during the operation of the unit, the attachment point of the upper link on the
machine should be higher than the attachment point of this link on the tractor,
•check lifting, lowering of the subsoiler and operation of all systems
Each tractor cooperating with the machine must be equipped with a set of weights
and maintain controllability in transport, i.e. at least 20% of the tractor’s weight
must be loaded on its front axle.
4.3. Maintenance and lubrication
•Each time after finishing work, the subsoiler should be cleaned of soil, and then
parts and assemblies should be inspected. Otherwise, if the rollers get stuck to the
soil, resulting in additional load, there may be problems with the operation of the
machine!
•After the first 4 hours of operation, retighten all screws and then periodically
check tightness. Failure to do so will cause the play to deepen and result in damage
to the machine.
•Lubricate the grease points on the hinge pins daily during the life of the machine.
Bearings of the tubular roller and leveling discs should be lubricated every 25 working
hours (does not apply to bearings of maintenance-free discs –these bearings do not
require maintenance and lubrication).
•When replacing worn parts, use thread locker, original screws and nuts.
•Always remember to tighten the screw connections properly.
CAUTION! Periodic lubrication is a guarantee of machine durability.
The durability and efficiency of the machine largely depends on regular lubrication. Use
mineral lubricants for lubrication. Lubrication points must be thoroughly cleaned before
pressing or applying grease.
CAUTION! It is forbidden to work on a damaged machine caused by any
event that resulted in cracking or deformation of the frame, roller or
other machine assembly!
4.4. Screw tightening torque
Screws and nuts should be tightened in the machine with the appropriate torque
depending on the strength class of the screw and its size and thread pitch. The
appropriate tightening torque values are shown in table 4.

16
Table 4. Tightening torque values for screws and nuts.
CAUTION! It is forbidden to work on a damaged machine caused by any
event that resulted in cracking or deformation of the frame, roller or other
machine assembly!
5Service
Due to the simplicity of its design and the materials used, the MGX subsoiler is
distinguished by a very low failure rate. To maximize uptime, follow all instructions in
this manual for operation, adjustment, lubrication, transportation, and storage of the
machine.

17
5.1 Daily service
•Each time after finishing work, the MGX subsoiler should be cleaned of soil, and
then parts and assemblies should be inspected. When cleaning, remove soil and
plant debris.
•After the first 4 hours of operation, retighten all screws and then periodically
check tightness.
•Worn out elements should be replaced with original new ones.
•When replacing worn parts, use thread locker, original screws and nuts.
•Always remember to tighten the screw connections properly.
CAUTION! Periodic lubrication is a guarantee of machine durability.
CAUTION! During maintenance works and replacements, the
unit should be secured against rolling. It should be connected to the
tractor with the parking brake on and the tractor engine should be
turned off. Use the correct spanners and protective gloves during
maintenance and repairs, and a helmet if necessary.
5.2 Off-season service
After the end of the working season, the subsoiler should be thoroughly cleaned,
the damage to the paint coating should be repaired, and the worn surfaces of the tines,
frame, strings and roller rings, as well as the threads of the adjusting screws should be
washed with “Antykor” kerosene and protected against corrosion with “Antykor 1”
grease, moreover full lubrication must be carried out. During a break in operation, it is
recommended to store the machine under a roof. However, if this is not possible, check
the condition of the protection from time to time and, if necessary, replenish the grease
washed away by rain.
5.3 Servicing the support wheel assembly
Check tire pressure regularly. In the event of a significant loss of air from the tires,
check the tightness of the air valve. Then take the wheel to a specialized workshop to
locate and repair the damage. Significantly damaged tires (especially profile damage)
must be replaced immediately.
6Replacement procedures
Replacing the tubular roller bearings
If the bearings are damaged, replace them as follows:
•place the machine on an even surface,
•unscrew the four screws securing the ball bearings on each side,
•remove the tubular roller,
•loosen both headless screws in each of the bearings and remove the bearings with
a puller,
•put new bearings loosely on the roller,
•roll the roller between the bearing plates and screw the bearings to them.
Tighten the headless screws using anti-loosening adhesive.

18
Replacement of operating elements
Excessively worn operating elements make it difficult to penetrate the tools and cause
an increase in operating resistance.
Replacement of working elements should be carried out with the machine lowered to
the ground, after switching off the tractor engine. To prevent the replaced elements
from touching the ground, place durable pads (e.g. wooden blocks with a thickness of
approx. 20 cm under the adjacent operating elements or the roller). After lowering the
subsoiler, switching off the tractor engine and pulling the handbrake, check the stability
of the tractor-machine unit. Only standard screws should be used to fasten new
elements.
In the case of repeated disassembly of the machine components, it is
necessary to check and, if necessary, replace the connecting elements, such as
screws, washers or nuts, whose excessive wear may lead to uncontrolled loosening
of the connected elements, and consequently their damage.
When working with extremely worn working tools, such work can cause
permanent damage to all machine assemblies. Tools should be replaced when their
wear exceeds the values specified in the manual. If the instructions are not
followed, damage may occur for which the manufacturer is NOT RESPONSIBLE!
Replacement of actuators
A malfunctioning actuator, unsealing, etc. should be replaced, dismantled and
sent to a specialist workshop. Actuators should be replaced with the machine
disassembled. Connect the actuator to the system and, mounted on one side it should
cycle several times in order to completely fill the actuator with oil. Otherwise, the
lowering section may fall suddenly.
CAUTION! During repairs and maintenance, the machine should be
lowered to the ground and supported on supports ensuring full stability,
and the tractor engine should be turned off. Use the correct spanners
and protective gloves during maintenance and repairs.
7Storage of the subsoiler
The subsoiler should be stored under a roof. In the absence of a roof, it is allowed to
store the machine outside.
The subsoiler should be stored in a place that does not pose a threat to people and
the environment. In the case of long-term storage of the machine outside, maintenance
of operating elements should be repeated when the preservative layer is rinsed off.
After disconnecting from the tractor, the machines should be supported on a hard and
even ground, maintaining permanent balance. All operating assemblies should rest on
the ground. The machine should be lowered so as to avoid impacts of operating
elements on hard ground. After lowering the machine, disconnect the suspension system
and drive the tractor away. Also, elements removed from the machine should be stored
firmly supported on the ground, excluding the possibility of uncontrolled movement. It is
recommended to store the machine in paved
and roofed places, inaccessible to unauthorized persons and animals.

19
Store the machine firmly supported on a hard surface in a way that
prevents injury to people or animals
8Disassembly and withdrawal
CAUTION! When disassembling the machine, take all precautions using
efficient tools and personal protective equipment. Disassembled parts
should be disposed of in accordance with the requirements of
environmental protection.
The unit used in accordance with the rules specified in the operating manual is
durable for many years, but worn or damaged elements should be replaced with new
ones. In the case of accidental damage (significant cracks and deformations of the
frames) that deteriorate the quality of the machine’s operation and pose a threat to its
further exploitation, the machine must be withdrawn from use.
Disassembly of the machine should be carried out by persons previously familiar
with its construction. These activities should be performed after placing the machine on
an even and hard surface. Disassembled metal parts must be scrapped.
