2.3. Intended use of the MBS straw breaker
Straw breakers are designed to mechanically break and remove straw from the soil
surface and aerate the soil by loosening the surface. With the MBS straw breaker, the
field is cleared of excess straw and the soil is aerated, which accelerates plant growth.
CAUTION! Failure to comply with the instruction manual shall also be
construed as misuse. The manufacturer shall not be liable for any damage
arising out of misuse.
3. General safety information
The MBS straw breaker may only be started, used and repaired by persons familiar with
its operation and that of the tractor being used and the rules for its safe use and operation.
The manufacturer shall not be liable for any unauthorised alternation of the straw breaker.
Only genuine original MANDAM spare parts shall be used during the warranty period.
The straw breaker must be operated with all precautionary measures, in particular:
•each time before starting operation check the implement and the tractor whether
their condition guarantees safety during operation and travel,
•minors under 16 years of age, ill, disabled or intoxicated persons (under the
influence of alcohol or drugs) must not operate the implement,
•use protective clothing, footwear and gloves during maintenance work,
•do not exceed the maximum axle loads and transport dimensions,
•use only original cotter pins and pins,
•do not approach the implement when it is being lifted or lowered, folded or
unfolded,
•do not stay between the implement and the tractor when the engine is running,
•move forward, lift and lower the implement slowly and smoothly without sudden
jerks, making sure that nobody stays in the vicinity,
•do not reverse and make U-turns when the implement is lowered to the working
position,
•when making U-turns do not use independent tractor brakes,
•during the operation and travel do not stand on the implement and do not put
additional loads onto it,
•while making U-turns, pay due caution if anyone is in the vicinity,
•do not operate the straw breaker on slopes with the inclination exceeding 12°,
•any repairs, lubrication or cleaning of working components may be performed as
long as the engine is not running and the straw breaker is lowered and unfolded,
•there is a hazard of head injury when you perform maintenance or replacement of
parts under the implement without adequate protection – wear a hardhat,
•during a break in the work, always lower the implement to the ground and stop the
tractor engine,
CAUTION! The MBS straw breaker is designed exclusively for field
processing. Using the implement for tasks that differ from the intended use
shall be regarded as misuse, resulting in loss of warranty.

11
•secure the extensions from uncontrolled opening while stationary and during
transport,
•driving and parking the implement on an unstable slope may cause sliding and soil
slipping,
•store the implement in a manner preventing injury to people and animals.
3.1. Hitching and unhitching to a tractor
•Make sure that the implement is hitched to the tractor in accordance with the
instructions, remembering to secure the bolts with cotter pins.
•While hitching the tractor with the straw breaker, do not stay between the
implement and the tractor.
•The tractor used together with the straw breaker must be fully functional and in
good working order. Do not attach the implement to a tractor with a defective
hydraulic system.
•Remember to observe the following: balance of the tractor and the suspended straw
breaker, tractor steerability and braking performance – the front axle load must not
drop below 20% of the total tractor load – a kit of front weights.
•In the rest position the implement unhitched from the tractor shall maintain a
stable balance.
3.2. Hydraulic system
The hydraulic system operates under high pressure. Take all precautionary
measures, in particular:
•do not connect and disconnect hydraulic hoses when the tractor hydraulic system
is pressurised (hydraulics set to neutral position),
•check regularly the conditions of connections and hydraulic hoses,
•do not use the implement until the hydraulic system is repaired.
CAUTION! On implements with folding side extensions, clean the machine
thoroughly after use so that excessive soil residues do not put additional
strain on the machine side extensions and thus on the cylinders!
3.3. Transport safety on public roads
For the period of transport, the side sections of the MBS straw breaker must be put
in transport position using the hydraulic system. The breaker should be protected from
unfolding by an automatic extension lock.
The clearance under the implement during the drive shall be at least 30 cm.
While transporting the straw breaker public roads, it is absolutely mandatory to use lights,
an identification sign and reflective side lights.
Do not exceed the maximum travel speeds:
–up to 25 km/h on smooth (asphalt) roads,
–6-10 km/h on country roads or cobblestones,
–up to 5 km/h on bumpy roads.
Adapt the drive speed to the road conditions to prevent the implement jumping on the
tractor’s three-point hitch. Maintain particular caution when passing and overtaking and
on bends. The maximum implement working width on public roads is 3.0 m. Do not drive
with the implement when the inclination of the slope with reference to the implement
exceeds 7º.

12
WARNING! Failure to observe the above rules may pose hazard to the
operator and other people and can lead to the implement damage. The user
shall be liable for any damage caused by failure to observe the rules.
According to the road traffic safety regulations (Regulation of the Minister of
Infrastructure of 31 December 2002, Journal of Laws No. 32 of 2002, item 262) – an
implement unit consisting of an agricultural tractor and an agricultural implement hitched
with the same must meet the requirements identical to those applying to the tractor
itself.
CAUTION! The implement protruding outside the rear side outline of the
tractor and obscuring tractor rear lights is a hazard for other vehicles driving
on the roads. Driving on public roads without adequate marking if forbidden.
The machine’s markings are:
•two portable warning plates mounted on the central frame of the machine. Rear-
mounted plates should be equipped with combination and reflective red lights
visible from the rear and white position lights visible from the front.
The manufacturer does not provide warning plates as standard equipment for the
machine. Warning plates are commercially available. The warning plates must be securely
fixed in the brackets and the plug must be connected to the tractor’s electrical installation
socket. Check the lights before transporting the implement.
Lift the implement and check the clearance between the lowermost part of the
implement and the ground which shall be minimum 30 cm.
3.4. Residual risk description
Mandam Sp. z o.o. makes every effort to eliminate the risk of accidents. However,
there is some residual risk that may result in an accident. The biggest hazard occurs
when/during:
•using the implement for purposes other than described in the manual,
•operating the implement by people who are underage and do not have licences,
are ill or intoxicated,
•presence of people and animals within the implement operating range,
•precautionary measures are not taken during transport and maneouvering with the
tractor,
•anyone gets between the implement and the tractor while the tractor’s engine is
running,
•maintenance and when the service and operation recommendations are not
observed,
•driving on public roads.
3.5. Residual risk assessment
The residual risk can be minimised by applying the following recommendations:
•operate the implement carefully and without undue haste,
•read the instruction manual carefully,
•keep a safe distance from hazard zones,
•do not stay on the implement and within the implement operating range when the
engine is running,

13
•perform the maintenance in accordance with safety rules,
•wear safety clothes and a safety helmet while working under the implement,
•prevent the access of unauthorized personnel and especially children to the
implement.
4. Information on operation and use
4.1. Preparation of the MBS straw breaker
Prior to operation check the technical condition of the straw breaker, in particular
that of the working parts and screw and bolt connections.
CAUTION! The permissible loads on the axles and tyre load capacities must
not be exceeded. The load on the front axle of the tractor must not be less
than 20% of the normal load.
Fig. 7 Diagram with markings of tractor loads.
Axle load calculations
Key:
GC– tractor’s gross weight,
TP– front axle load for the unhitched tractor,
TT– rear axle load for the unhitched tractor,
GP– total weight of the rear-mounted implement,
Gt – total weight of the front-mounted implement,
a – distance between the centre of gravity of the front-mounted implement and the axle
centre,
b – tractor wheelbase,
c – distance between the rear axle centre and the centre point of the hitching pin of the
rear-mounted implement,
d – distance of the centre of gravity of the implement from the hitching pins of the tractor
(assume 1.5 m for hitched implements, and 3 m and 0.7 of weight for semi-hitched
implements),
x – distance of the centre of gravity from the rear axle (assume 0.45 if the manufacturer
does not provide this parameter).

14
Minimum load at the front in case of a rear-mounted implement:
Actual load on the front axle
Actual total weight
Actual load on the rear axle
4.2. Hitching the straw breaker with the tractor
Tyre pressure in the tractor wheels must comply with the values recommended by
the manufacturer. The lower bars of the three-point hitch should be at the same height,
spaced correspondingly to the spacing of the hitch lower points. While attaching the
machine to the tractor, the implement must be placed on hard and even ground.
Fig. 8 Three-point hitch of the tractor: 1,2 – lower bars, 3 – upper fastener, 4 – left support rail, 5 – right
support rail with adjustable length, 6 – lift arm, 7 – lift shaft
While attaching the MBS straw breaker to the tractor, complete the following steps:
•switch the tractor hydraulic system into adjustment position,
•remove lower hitch bolts (if the tractor three-point hitch is not equipped with
hooks),
•reverse carefully, suspend the implement on the lower bars and secure,
•attach the tractor’s upper fastener (in case of implements without chassis) – during
the operation of the implement, the hitch point of the upper fastener at the
machine must be higher than the attachment point of this fastener at the tractor,
•check the lifting, lowering of the straw breaker and the operation of the hydraulic
system.

4.3. Operation and adjustment
Unlock the mechanical protection of the side sections before unfolding for use.
4.4. Protection against unfolding
The MBS straw breaker, when folded, must be secured against unfolding with an
automatic side extension lock. The lock uses a mechanism consisting of a cylinder
and a hook (Fig. 9).
Fig. 9 Implement with automatic side extension locking mechanism
4.5. Implement opening sequence
Before unfolding the folding side the extensions of the machine, learn the opening
sequence to perform this operation correctly.
1. First, raise the implement as much as possible to be able to fold it correctly,
avoiding the risk of the folding arms catching on the ground during movement
(Fig. 10).
2. Next, fold the implement side extensions hydraulically into the “closed” position
to ensure that the side extension lock mechanism will unlock and allow the
implement arms to be opened at a later stage. This operation is necessary each
time the arms are opened (Fig. 10).
Hook
Cylinder

16
Fig. 10 Implement opening sequence: 1- raise the implement up to the maximum, 2- fold the side
extensions into the “closed” position.
3. Then, after making sure that the hook of the hydraulic side extension lock
mechanism allows the machine side extensions to be unlocked, proceed to open
them fully (Fig. 11).

17
Fig. 11 Implement opening sequence: 3- release the hook of the hydraulic side extension lock mechanism,
4-open the implement side extensions.
4. When opening the implement’s side extension arms, make sure that the ends of
the arms are at the correct height to prevent them from catching on the ground
(Fig. 12).
Fig. 12 Implement opening sequence: open the implement paying particular attention to the height of the
arm ends from the ground.

18
5. To complete the opening sequence of the implement side extensions, wait until
the hydraulic mechanism opens the arms to their end position. Do not interrupt
the opening process of the arm side extensions without ensuring that they are
fully open.
Fig. 13 View of the implement at the completion of the side extension opening sequence. The implement
arms are fully open.
4.5.1. INTERLOCK ASSEMBLY INSTRUCTIONS
Pre-set the position of the claw assembly in the straw breaker before working in the field.
Also level the machine lengthwise with the tractor upper fastener or with the tractor’s
turnbuckle or with the drawbar turnbuckle and laterally with the support rail of the right
lower bar on the tractor. Then, make the first work passage to set the optimum working
speed and to correct the adjustment based on an assessment of the correct operation of
the individual components. The recommended operating speed should be 10 - 15 km/h.
In a well-adjusted machine, the frame should be parallel to the ground and both working
units must be equally recessed in the soil over the entire working width.
4.5.2. Claw tilt adjustment
The MBS straw breaker is equipped with hydraulic adjustment of claw tilt angle; by
extending the actuator they are plumbed them and by retracting the actuator they are
levelled. Adjust the claw angle only when the machine is lifted on the three-point hitch.

4.6. Maintenance and lubrication
•Clean the straw breaker from soil after each use and inspect the parts and
assemblies. Otherwise, in the case of the components being clogged with soil and the
additional load occurring due to this, there may be a problem with the folding of the
implement.
•After the first 4 hours of operation, re-tighten all bolts and periodically check them
for tightness. Failure to do so will exacerbate play and backlash and result in damage
to the implement.
•Lubricate the lubrication points on the hinge bolts daily during the machine’s
service life.
•Use thread adhesive and only genuine screws and nuts when replacing worn parts.
•Always remember to tighten the screwed joints properly.
CAUTION! Periodic lubrication guarantees the long service life of the machine.
The long service life and efficiency of a machine depends to a large extent on regular
lubrication. Use mineral greases for lubrication. Clean the lubrication points thoroughly
before pressing or applying grease.
CAUTION! It is forbidden to work on a damaged machine caused by any
event resulting in a broken, or deformed frame, roller or other assembly
of the machine!

5. Operation
5.1. Daily maintenance
•Clean the MBS straw breaker from soil after each use and inspect the parts and
assemblies. When cleaning, remove plant residues and ropes wound at the bearing
points.
•After the first 4 hours of operation, re-tighten all bolts and periodically check them
for tightness.
•Lubricate the lubrication points on the hinge bolts daily during the machine’s
service life.
•Use thread adhesive and only genuine screws and nuts when replacing worn parts.
•Always remember to tighten the bolt connections properly.
CAUTION! Periodic lubrication guarantees the long service life of the implement.
Fig. 15. MBS straw breaker lubrication points.
CAUTION! During maintenance and replacement works, the implement
should be protected against overturning. It should be connected to the
tractor with the parking brake on, and the tractor engine should be turned
off. The side sections should be unfolded. During repairs and
maintenance, use proper spanners and safety gloves; wear hardhat if
necessary.
