The single knife rollers 3.0, 3.5 and 4.0 are not foldable and are attached to the front or
rear tractor three-point hitch. When attached to the rear three-point hitch, it is possible
to suspend an additional unit behind the roller, e.g. a disc harrow. The front three-point
hitch adapter should be removed in such case and an additional unit should be attached
in its place using bolts.
The Tandem foldable knife rollers in the working width of 4.0, 5.0 and 6.0 are adapted to
be attached to the front three-point hitch. They also feature a floating drawbar stabilized
with springs. When the pins are properly interlocked and the working rollers are rotated,
it is possible for the roller to work on the tractor’s rear hitch.
The single and tandem knife rollers with working widths 4.0H, 5.0H and 6.0H have a middle
frame and lateral frames which are hydraulically folded to the transport position (Fig. 3
and 4).

2.2 Intended use of the knife roller
The knife roller is used for an intensive shredding of straw and post-harvest crop
residue, along with crushing and partial covering. This speeds up the decomposition of
crop residue, facilitating further post-harvest cultivation. The knife roller is also a perfect
tool for fighting the European corn borer.
The working part of the roller is an openwork drum with cutting knives bolted on its
circumference. The knives are made of the HARDOX wear resistant steel. The knives
should operate on the field surface. The knife roller shall not penetrate into the soil
deeper than 2-3 cm.

CAUTION! The roller is designed for agricultural use only. Using the
implement for tasks that differ from the intended use shall be regarded as
misuse, resulting in loss of warranty.
CAUTION! Failure to follow the guidelines included in this instruction manual
shall be regarded as misuse. The manufacturer shall not be liable for any
damage arising out of misuse.
As an option, single and tandem knife rollers can be equipped with frame-mounted
upper covers to protect the tractor from the spread of post-harvest crop residue or
stones caused by the working rollers. On tandem knife rollers HD, these protection
covers are mounted on the machines as standard.

3. General safety information
The roller can be operated and repaired only by persons familiar with its operation and
the attached tractor as well as the rules of safe operation and maintenance of the knife
roller. The manufacturer shall not be responsible for any arbitrary modifications of the
construction of the roller. Only genuine MANDAM spare parts shall be used during the
warranty period.
The roller must be operated with all precautionary measures, in particular:
•each time before starting operation check the roller and the tractor whether their
condition guarantees safety during operation and travel,
•minors, disabled or intoxicated persons (under the influence of alcohol or drugs)
must not operate the machine,
•wear work clothes, shoes and gloves during maintenance,
•do not exceed permissible axle and tyre loads or transport dimensions,
•use only original cotter pins and pins,
•do not approach the roller while it is being lifted or lowered,
•do not stay between the roller and the tractor while the engine is running,

14
•move forward, lift, and lower the roller 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,
•do not stand on the implement or apply additional loads during operation and
transport,
•while making U-turns, pay due caution if anyone is in the vicini t y,
•do not operate the roller 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 roller is lowered,
•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,
•foldable rollers have a mechanical lock that prevents an uncontrolled lowering of
the side extensions,
•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 with the tractor
•Hitch the implement with the tractor according to the recommendations, use pins
and protect the pins with cotter pins.
•While hitching the tractor with the roller, do not stay between the implement and
the tractor.
•The tractor used together with the roller 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
implement, 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.
•The supporting foot should be used on a stable ground. Do not use supporting plates
under the foot as this may cause instability of the support.
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),
•regularly check the conditions of connections and hydraulic hoses,
•do not use the implement until the hydraulic system is repaired.
3.3. Transport on public roads
Before driving on public roads, fold the lateral sections of knife rollers 4.0H, 5.0H and
6.0H to the travel position using the hydraulic system. Before folding, the machine must
be lifted sufficiently high until the folded side sections do not collide with the ground.
The knife roller must be protected against unfolding by means of the mechanical lock.

15
The clearance under the implement during the drive shall be at least 30 cm.
While transporting the implement on 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 20 km/h on smooth-surface (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 roller jumping on the three-
point hitch and to prevent excessive loads on the implement frame and the three-point
hitch.
Act with due caution when passing and overtaking or travelling at curves. The permissible
width of the agricultural machinery moving on public roads is 3.0 m.
WARNING! Any failure to observe the above rules may pose hazard to the
operator and other people. It may also result in damaging the machine. The
user shall be liable for any damage caused by failure to observe the rules!
3.4. Description of residual risk
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,
•staying on the implement or between the tractor and the implement when the
motor is running,
•maintenance and when the service recommendations are not observed,
•driving on public roads.
3.5. Residual risk assessment
The residual risk can be minimized 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,
•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. General information on the use of the implement
Before the machine is put into operation for the first time:
•read the instruction manual,
•make sure that the machine is in proper operating condition,
•check the condition of the hydraulic system (replace damaged components, e.g.
pressure hoses),
•make sure that the hydraulic hose quick-connector of the machine match the
tractor sockets,
•check the tightening of bolts and nuts,
•check if the air pressure in tyres is according to the manufacturer’s
recommendations,
•make sure that all components requiring lubrication are lubricated,
•make sure the tyre pressure in the tractor wheels is equal on both axes to ensure
even operation.
WARNING! Do not exceed the maximum permissible axle and tyre loads. The
front axle load must not be less than 20% of the total load. Tyre pressure
must comply with the values recommended by the manufacturer.

4.1. Hitching the roller 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 lower points of suspension. While attaching
the roller to the tractor, the implement must be placed on hard and even ground.
Fig. 7 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 roller to the three-point hitch of the tractor, follow the steps as
below:
•switch the tractor hydraulic system into adjustment position,

18
•remove lower hitch bolts (if the tractor lift is not equipped with hooks),
•drive forwards carefully, suspend the implement on the lower bars and secure,
•attach the tractor’s upper fastener. During operation of the unit, the hitch point of
the upper fastener at the unit must be located higher than the attachment point
of this fastener at the tractor,
•check the operation of roller lifting, lowering and the hydraulic system.
CAUTION! Hitching the tractor with the roller must be performed carefully,
at the tractor’s minimum speed! When hitching the implement, make sure
that no bystanders are present in the vicinity.
4.2. Operation and adjustment
Start working with the roller by making the first trial passage. During this task, check
roller adjustment and manner of operation. If necessary, adjust the length of the tractor
fastener so that the roller frame is positioned horizontally. The working depth of the knife
roller is adjusted by means of the turnbuckles (Fig. 8). The knives should operate on the
field surface. The knife roller shall not penetrate into the soil deeper than 2-3 cm. The
working speed on the field with the roller attached should not exceed 15 km/h. A correctly
hitched and adjusted roller should evenly travel before or behind the tractor and evenly
shred the post-harvest residue at its entire working width.
Fig. 8 Knife roller working depth adjustment
4.2.1 Setting theknife direction
Tandem knife rollers in 3.0 m, 3.5 m and 4.0 m widths in the non-folding version are
factory-prepared for both front-and rear-mounted operation using the tractor’s three-
point hitch. When attached to the rear three-point hitch, it is possible to suspend an
additional unit behind the roller, e.g. a disc harrow. The front three-point hitch adapter
should be removed in such case and an additional unit should be attached in its place
using bolts.
The Tandem foldable knife rollers in the working width of 4.0, 5.0 and 6.0 are adapted to
be attached

to the front three-point hitch. They also feature a floating drawbar stabilized with
springs. When the pins are properly interlocked and the working rollers are rotated, it is
possible for the roller to work on the tractor’s rear hitch.
Fig. 9 Setting the tandem knife roller for front hitch operation
In order for the implement to work properly on the rear hitch, the floating position locking
bolt must be locked and the rollers must be turned to ensure the correct direction of the
knife (Fig. 11).

CAUTION! Do not operate the roller on stony soil because the working
elements on the roller may become cracked.
CAUTION! The knife roller shall not penetrate into the soil deeper than 2-3
cm as this can cause an excessive wear of the roller working parts. The roller
should operate on the surface of the field.
CAUTION! Folding rollers cannot work on the rear hitch without proper
preparation by interlocking the locking pin and rotating the working rollers
accordingly.
4.3. Maintenance and lubrication
•Clean the knife roller from soil after each use and inspect the parts and assemblies.
Otherwise, there may be a problem with the folding of the machine if the rollers are
clogged with earth and there is an additional load!
•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.
