Purpose of the SAL disc harrow
The disc harrow is designed for post-harvest cultivation (with chopped straw) and pre-sowing in both ploughing and ploughless technology. The unit can also be used for mixing catch crops into the soil or cultivating wasteland overgrown with tall volunteer seeds.
The working elements are toothed discs with a diameter of 620 mm in two staggered rows, mounted on posts secured by springs. Equipping each disc with its own maintenance-free bearing allows the disc to be optimally inclined to the direction of travel and the ground. This allows the stubble to be thoroughly undercut, and harvest residues to be evenly mixed and broken up. As a result, soil evaporation is interrupted, plant residues decompose more quickly and there is a reduction in the intensity of phenolic compounds negatively affecting the development of succeeding plants. The too thing of the discs aids penetration. The shaft located at the rear of the machine compacts the soil, resulting in faster emergence of weeds and volunteer seeds. The use of a disc harrow before sowing ensures thorough mixing of fertilizer into the soil, levelling of the surface and proper soil structure.
NOTE! The disc harrow is designed
exclusively for agricultural use. Use for any other purpose will be construed
as misuse and will void the warranty. Failure to comply with the
recommendations in these operating instructions will also be construed as
misuse.
NOTE! MANDAM provides a guarantee for
maintenance-free hubs under the following conditions:
-
* comply with the principle of replacing the working discs in the event of wear, which must not exceed 520mm in diameter for discs Ø620mm,- use the original MANDAM plates,
- not to exceed the permitted working depth, which is 11cm,
- observe the rule prohibiting the turning manoeuvre with the harrow when it is in the working position (working discs buried in the soil).
NOTE! The manufacturer is not liable
for damage resulting from the operation of the machine not in accordance with
its intended use.
General safety rules
The disc harrow may only be started up, used and repaired by persons who are familiar with its operation and the associated tractor and with the rules of conduct for the safe operation and handling of the disc harrow. The manufacturer is not responsible for arbitrary changes to the harrow design. During the warranty period, only factory made “MANDAM” parts must be used.
- The disc harrow should be operated with all precautions in mind, in particular:
- before each start-up, check that the disc harrow and the tractor are in safe working order,
- use of the machine by minors, persons who are ill or under the influence of alcohol or other intoxicants is prohibited,
- use work clothes, footwear and gloves when carrying out maintenance work,
- permissible axle loads and transport dimensions must not be exceeded,
- use only original safety and split pins,
- do not approach the disc harrow while it is being raised or lowered,
- it is not permitted to stay between the tractor and the disc harrow when the engine is running,
- when moving the disc harrow, lift and lower it slowly and gently without sudden jerks, taking care not to allow any bystanders to be in the vicinity,
- it is forbidden to reverse the tractor or make a U-turn with the machine lowered into the working position,
- the tractor’s independent brakes must not be applied during turning,
- do not stand on the machine or put any additional weight on it during operation or transport,
- during u-turns, special care should be taken if there are bystanders in the vicinity,
- disc harrows must not be operated on gradients greater than 12°,
- carry out any repairs, lubrication or cleaning of working parts only with the engine switched off and the machine lowered and unfolded,
- during maintenance and when replacing parts, going inside or underneath the machine without adequate protection can cause head injuries – a helmet should be used in this case.
- when not in use, lower the machine to the ground and stop the tractor engine,
- harrows with a working width greater than 3.00 m are fitted with a mechanical lock to prevent the wings from opening uncontrolled when stationary and during road transport,
- driving and parking the unit next to a slope with unstable ground may cause a landslide.
- machinery must be stored in such a way as to prevent injury to people and animals.
Proper coupling and uncoupling with the tractor
- The attachment of the machine to the tractor must be made as specified, remembering to secure the pins and to secure the suspension pins with split pins.
- When coupling the tractor to the disc harrow, it is forbidden for people to stay between the machine and the tractor during this time.
- The tractor working with the disc harrow must be fully operational. It is forbidden to couple the harrow with a tractor with defective pneumatic (if the machine has a braked axle) and hydraulic systems.
- Make sure that the tractor with the attached unit is stable, and the tractor steerability and stopping power can be maintained. The load on the front axle cannot drop below 20% of the total load on the tractor axle – set of front-mounted weights.
- In the resting position, the machine, when uncoupled from the tractor, should maintain a stable equilibrium.
- The support foot should be rested on a stable surface. It is forbidden to use foot pads that may cause instability of the support.
Tyres
- Tyre pressures must not exceed those recommended by the manufacturer and it is forbidden to transport the machine at too low a pressure. This may damage the machine and cause an accident on large uneven surfaces and when driving too fast.
- Significantly damaged tyres (particularly profile damage) must be replaced immediately.
- When replacing tyres, the machine must be secured against rolling.
- Repair work on wheels or tyres should be carried out by persons trained and authorised for this purpose. This work should be carried out with appropriately selected tools.
- Each time the wheels are fitted, the tightness of the nuts should be checked after 50km.
Hydraulic and pneumatic systems
The hydraulic and pneumatic system is under high pressure. All precautions
should
be taken, in particular:
- do not connect or disconnect the hydraulic lines when the tractor’s hydraulic system is under pressure (hydraulics set to neutral),
- regularly check the condition of the connections and the hydraulic and pneumatic hoses.
- the unit must be taken out of service while the hydraulic or pneumatic failure is being rectified.
Safety regarding transport on public roads
For transport, the shaft must be folded into the transport position and
secured
with pins on a ladder.
During transport, the clearance under the machine should be at least 30
cm
When transporting the unit on public roads, the use of a luminous device, a
distinguishing sign and side reflectors is mandatory.
The travelling speed during transport must not be exceeded:
- on roads with a smooth surface (asphalt) up to 25 km/h,
- on dirt or paved roads 6-10 km/h,
- on bumpy roads not more than 5 km/h.
The driving speed must be adapted to the condition of the road and the conditions on the road so that the unit does not jump up on the tractor’s suspension system. Take extra care when passing, overtaking and on bends. The permissible operating width of the machine when travelling on public roads is 3.0 m. It is forbidden to transport the unit where the slope preceding the aggregate exceeds 7º.
WARNING! Failure to comply with the above rules may create hazards for the operator and bystanders as well as damage to the machine. Damage resulting from non-compliance with these rules is the responsibility of the user.
In accordance with the road safety
regulations (Regulation of the Minister of Infrastructure of 31.12.2002.
Journal of Laws No. 32 of 2002 item 262) – a unit consisting of an
agricultural tractor and the agricultural machinery that is coupled with it
must meet the same requirements as the tractor.
NOTE! The unit as a part of the vehicle
protruding beyond the rear side contour of the tractor obscuring the rear
lights of the tractor poses a danger to other vehicles on the road. It is
forbidden to travel on public roads without appropriate markings
The manufacturer does not supply warning signs as standard equipment on the machine. Warning signs are available commercially. The warning boards must be securely mounted in the brackets and the plug connected to the socket of the tractor’s electrical system. Check the operation of the lights before starting the transport. After lifting the machine, check the clearance under the lowest working elements, which should be at least 25 cm. The permissible transport speed of the tractor with the machine is 15 km/h. It should be reduced to 10 km/h on roads with poorer surfaces and 5 km/h on dirt roads. Extreme caution should be exercised when passing and overtaking other vehicles, avoiding obstacles and crossing large irregularities in fields and dirt roads.
Description of residual risk
Madam Sp. z o.o. makes every effort to eliminate the risk of accidents. There is however, a residual risk that could result in an unfortunate accident. The greatest danger occurs when:
- using the machine for purposes other than those described in the instructions,
- using the machine by minors, persons who are not authorised, who are ill or who are under influence of alcohol or other drugs,
- persons and animals within the operating range of the machine are present,
- no caution is paid when transporting and manoeuvring the tractor,
- staying on the machine or between the machine and the tractor while the engine is running,
- operating and failure to comply with operating instructions,
- driving on public roads.
Assessment of residual risk
Residual risk can be minimised by applying the following recommendations:
- prudent and unhurried operation of the machine,
- careful reading of operating instructions,
- keeping a safe distance from danger zones,
- prohibition on being on the machine and in the operating area of the machine while the tractor engine is running,
- carrying out maintenance work in accordance with safety rules,
- use of protective clothing and, if working under machinery, a helmet,
- prevention of unauthorised access to the machines, especially by children.
Information on handling and use
Before starting the machine for the first time:
- refer to the operating instructions,
- make sure the machine is in good working order,
- check the condition of the hydraulic and pneumatic systems (replace components if damaged, e.g. pressure lines),
- make sure that the machine’s pressure hose couplings fit into the sockets on the tractor,
- check the tightness of the individual bolts and nuts,
- check the air pressure in the wheels in accordance with the manufacturer’s recommendations,
- ensure that all components requiring lubrication are lubricated,
- ensure that the pressure in the tractor wheels is the same on each axle to ensure even operation.
Preparing the disc harrow
The disc harrow is usually delivered to the customer ready for use. However,
due to the limitations of transport facilities, it is also possible to deliver
it in a partially dismantled state – this usually involves disconnecting the
shaft. When the unit is first prepared for operation, its components (shaft)
must be assembled. To do this, place the disc harrow on flat paved ground in a
position that allows the shaft to maneuver. Use a lifting device to transport
the shaft. Position the arms in the harrow brackets and bolt together at the
desired extension (Fig. 4 – No. 1), then secure the arms with the pins in the
ladders while adjusting the desired height (Fig. 4 – No. 2).
NOTE! The correct procedure for mounting
the shafts in the arm holders requires that the bolts be evenly tightened
diagonally, so that the entire plane of the arm holders is adjacent to the
plane of the shaft clamp profile. This provides the most secure way of
connecting the shaft arms to the machine!
Fig. 3 Connection of the arms with shaft bracket.
Fig. 4 View of the SAL disc harrow with the fixing points of the roller arms,
1 – pin fixing, 2- bolt + nut
fixing.
Before starting work, check the technical condition of the unit, especially the condition of the working parts and screw connections.
NOTE! The permissible axle loads and tyre
load capacities must not be exceeded. The load on the front axle must not
be less than 20% of the total load.

Coupling the disc harrow to the tractor
The tractor wheel tire pressure should be in accordance with the manufacturer’s recommendations. The lower links of the three-point hitch should be at an equal height, at a spacing corresponding to the spacing of the lower suspension points. When connecting the disc harrow to the tractor, the harrow should stand on firm and level ground.
ig. 6 Three-point suspension system of the tractor’s three-point hitch: 1,2 – lower links, 3 – upper fastener, 4 – left suspension, 5 – right suspension with adjustable length, 6 – lift arm, 7 – lift shaft
When attaching the SAL disc harrow to the tractor, do the following:
- switch the tractor’s hydraulic system to position control,
- remove the lower link pins if the tractor’s three-point hitch is not equipped with hitching hooks,
- carefully back up, suspend the machine from the lower links, then secure,
- connect the upper link on the tractor (on units not equipped with a trolley) – when the unit is running, the attachment point of the upper link on the machine should be higher than the attachment point of this link on the tractor,
- check the lifting and lowering of the pre-seed unit and the operation of the hydraulic system.
Any tractor that is used with the machine must be equipped with a set of weights and must remain steerable during transport, i.e. a minimum of 20% of the tractor’s weight must be on the front axle.
Coupling the seed drill to the disc harrow
Before suspending the seed drill, familiarise yourself with the weight of the
drill
including the seed. The load capacity of the hydropack is 1,300 kg. When
coupling the
seed drill to the disc harrow, do the following:
-
* match the spacing of the towing hooks to the spacing of the seed drill pins by placing a hook on the appropriate side of the arm and shimming the spacer plate accordingly,- lower the lower links of the hitch below the hitching pins of the seed drill (in the case of a trolley hitch, insert a pin into the appropriate hole in the hangers of the hitch, then adjust the position with a cylinder),
- reverse the set so that the seed drill pins are in the hooks,
- insert the safety device into the pins, hole in the hooks and secure with a safety pin,
- connect the top link to the seed drill
NOTE! Before raising the disc harrow, the
seed drill must be raised for the stability of the unit.
Operation and adjustment
On the SAL disc harrow, the position of the individual working units must be preadjusted before starting work in the field. It is also necessary to level the machine longitudinally with the tractor’s top link and transversely with the lower link hanger. The first working run should then be made to set the optimum working speed and correct the adjustment based on an assessment of the correct operation of the individual units. The working speed should be 10 – 15 km/h. In a well-adjusted machine, the frame must be parallel to the ground and all working units should penetrate the soil equally across the entire working width.
Adjusting the shaft position
The position of the shaft can be adjusted in 2 ways, changing its offset from
the discs and the working depth, these are described below:
The w orking depth is determined by locking the shaft arms using locating pins with locating plates on the ladder at the desired height. Particular care must be taken to ensure that the pins are fitted equally on both sides.
Fig. 7 Adjusting the working dep
Caution ! When setting the working depth,
take into account the sinking of the shaft into the ground depending on
the condition of the surface and the type of crop
Distance of the shaft from the discs – extend the unlocked arms to the desired distance and then secure with screws on the handle. However, it must be remembered that moving the shaft backwards causes the machine to lengthen and worsens the longitudinal balance of the tractor.
Fig. 8 Adjusting the shaft offset from the discs.
Setting up side screens
The side screen should be positioned and locked with screws at such a height that the screen is above the soil surface and not exposed to the impact of stones and the hanging of crop residues. If required, it should also be moved forwards or backwards (remounting on the holes) so that it retains the soil rejected by the outermost front disc and rakes the furrow behind the outermost rear disc.

Setting up the machine correctly for operation
The machine must be set up parallel to the ground for operation (see Fig.10).
The front drawbar should be aligned horizontally. It is forbidden to operate
the machine with the drawbar at an angle!

tractor.
Rules for transporting the harrow on public roads and lighting the
machine
In accordance with the 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 the agricultural tractor and the agricultural machine coupled with it must meet requirements identical to those imposed on the tractor itself.
NOTE! The unit as a part of the vehicle
projecting beyond the rear side contour of the tractor obstructing the
tractor’s rear lights poses a danger to other vehicles on the road. Be sure to
observe the transport recommendations given in section 3 “General safety
rules”. It is forbidden to travel on public roads without proper signage.
The units should be equipped with:
- triangular plaque distinguishing slow-moving vehicles,
- two forward-facing plates having a white running lights and a white retro-reflector,
- two rear-facing plates having a combination light and a red reflector. The boards should be painted in slanted red and white stripes.
Once the plates have been fixed, the electrical wires of the warning-light device should be connected to the socket of the tractor’s electrical installation.
The manufacturer does not supply warning signs as standard equipment on the machine. Warning signs are available commercially.
Driving style should always be adapted to the road conditions – this will help avoid accidents and damage to the chassis. Consider your own skills and the intensity of the movement, the prevailing visibility and the weather.
Before transporting, the machine should be cleaned from the soil and the operation of the lights checked. After lifting the machine, check the clearance under the lowest working elements, which should be at least 25 cm. The permissible transport speed of the tractor with the machine is 15 km/h. It should be reduced to 10 km/h on roads with poorer surfaces and 5 km/h on dirt roads. Extreme caution should be exercised when passing and overtaking other vehicles, avoiding obstacles and crossing large irregularities in fields and dirt roads.
Maintenance and lubrication
- The disc harrow must be cleaned of soil after each operation, followed by an inspection of the parts and assemblies.
- Re-tighten all screws after the first 4 hours of operation and periodically check the tightness.
- Lubricate the grease points on the hinge pins daily during the life of the machine. Lubricate the bearings of the tubular shaft and the levelling discs every 25 operating hours (this does not apply to the maintenance-free bearings of the discs – these bearings do not require maintenance and lubrication).
- When replacing worn components, use thread glue, original bolts and nuts.
- Always ensure that screw connections are properly tightened.
NOTE! Periodic lubrication is a guarantee of the durability of the machine.
The service life and efficiency of the machine depend to a large extent on regular lubrication. Mineral lubricants should be used for lubrication. Lubrication points must be thoroughly cleaned before pressing in or applying grease.
Torques for tightening screws
Bolts and nuts should be tightened in the machine with the correct torque depending on the strength class of the bolt and its thread size and pitch. Their respective tightening torque values are shown in Table 3.

frame, shaft or other assembly of the machine!
Operation Everyday service
- Every time the BEST pre-sowing unit is finished working, the soil must be cleaned and the parts and components inspected. During cleaning, plant debris and strings winding up at the bearing points of the shafts must be removed.
- Re-tighten all screws after the first 4 hours of operation and periodically check the tightness.
- Lubricate the shaft bearings every 25 operating hours during the life of the machine.
- When replacing worn components, use thread glue, original bolts and nuts.
- Always ensure that screw connections are properly tightened.
NOTE! Periodic lubrication is a guarantee of the durability of the machine.
**Fig. 15 Lubrication points of the SAL harrow.
**
The service life and efficiency of the machine depend to a large extent on regular lubrication. Mineral lubricants should be used for lubrication. Lubrication points must be thoroughly cleaned before pressing in or applying grease.
Post-season service
After the working season, the disc harrow must be thoroughly cleaned, any damage to the paintwork repaired and the worn working surfaces of the discs, roller rings and 25 the threads of the adjusting screws cleaned with ” ” paraffin and protected against corrosion with “Antenor 1” grease, in addition to a full lubrication. It is advisable to store the machine under a canopy when not in use. However, if this is not possible, the condition of the protection should be checked from time to time and, if necessary, the rain- washed grease should be replenished.
NOTE! During maintenance work, the unit
should be secured against rolling (it should be connected to the tractor
with the parking brake on) and unfolded.
Replacement procedures
Bearing replacement
If the bearings are damaged, they must be replaced:
- place the machine on a horizontal surface,
- unscrew the four screws holding the ball bearings on each side,
- move the tubular shaft away,
- loosen the two headless screws in each bearing, and pull the bearings off with an extractor,
- fit the new bearings loosely onto the shaft,
- roll the shaft between the bearing plates and screw the bearings to them. Screw in headless screws using adhesive to prevent loosening.
- do not replace the ball bearings on the disc holders,
- In the event of damage, replace the entire disc holder.
Replacement of working components
Excessively worn elements make it difficult for tools to penetrate, increase
operating resistance and can damage the machine. The discs should be replaced
with new ones when their diameter reduces to 520 mm.
The working components must be changed on the machine lowered to the ground
after the tractor engine has been switched off. To ensure that the elements to
be replaced do not come into contact with the ground, sturdy shims (e.g.
wooden blocks approx. 20 cm thick underneath adjacent elements or the shaft)
must be provided. In the case of a trolley, the maximum lowered wheels can
also be used as supports. After lowering the harrow, switching off the tractor
engine and applying the handbrake, check the stability of the tractor-machine
combination. Only typical screws should be used to fix new components.
If machine components are disassembled several times, it is necessary to inspect and possibly replace connecting elements such as bolts, washers or nuts, excessive wear of which may lead to uncontrolled loosening of the connecting elements and subsequent damage.
When working on extremely worn work tools, such work can cause, for example, bearing damage in the case of a small disc diameter. Tools should be replaced when their wear and tear exceeds the limits allowed by the manual. If the recommendations are not followed, damage may occur for which the manufacturer is NOT RESPONSIBLE!
NOTE! When carrying out repairs and
maintenance, the machine should be lowered to the ground and supported on
supports to ensure full stability and the tractor engine switched off. Use
proper spanners and protective clothing during maintenance and repairs.

Storage of the disc harrow
The disc harrow should be stored under cover. In the absence of a covered area, outdoor storage of the machine is permitted.
Parts and assemblies should be inspected after the working season. If damage or significant wear is found, replace the relevant parts with new ones. Clean areas of paint damage from dirt, rust and touch up with anti-corrosion paint, then top coat. Protect the working surfaces of the disc harrow and roller from corrosion. It is advisable to store the machine under a canopy when not in use. However, if this is not possible, the condition of the protection should be checked from time to time and the maintenance of the working elements should be repeated when the preservative layer is rinsed away by rain.
Clean the piston rods of the hydraulic cylinders during winter and when the machine is not in use for a long period of time, and protect them with Vaseline or acid-free grease to protect them from corrosion.
The machine, when uncoupled from the tractor, should support itself on firm and level ground, maintaining a firm balance. All work units should rest on the ground. The machine should be lowered gently so as not to expose the working parts to impact on hard ground. Once the machine is down, disconnect the suspension system and drive the tractor away. Also, components dismantled from the machine must be stored securely on the ground, excluding the possibility of uncontrolled movement. It is advisable to store the machine in a paved and covered area that is inaccessible to bystanders and animals.
NOTE! The disc harrow should be stored in
a place that does not pose a danger to people or the environment.
Store the machine securely supported on a
hard surface to prevent injury to people or animals.
Disassembly and disposal
A machine used in accordance with the rules in the operating instructions will
last for many years, but worn or damaged components must be replaced with new
ones. In the event of emergency damage (cracks and deformation of the frames)
