Safety
You will see this symbol in the instruction manual each time advice is given
about your safety, the safety of other users, or the functional safety of the
machine. All safety instructions must be observed and made available to all
users of the mulcher.
In addition, the safety instructions provided by the tractor manufacturer must
be followed.
If the stubble cultivator is used on a public road, de corresponding traffic
regulations apply.
Even though a broad range of risks have been mentioned here, it is impossible
to foresee all eventualities, resulting from varying conditions under which the
appliance might be operated. No amount of good advice can replace “common
sense” and “paying attention” at any given time, but the instructions mentioned
above are a great start to a safe and secure operation of your DALBO stubble
cultivator.
General
•Before starting its operation, the user must be familiar with all parts of the
stubble cultivator.
•Safety labels have been placed on the machine. These contain important
instructions about your own safety and that of others, as well as the correct
use of the stubble cultivator.
•There may be no passenger on the machine during work or transportation.
•When operating the stubble cultivator, ensure that there are no persons
within the machine’s radius of action. The stubble cultivator may only be
operated from inside the tractor.
•Before leaving the tractor, or if adjustments, maintenance or repairs need to
be made to the stubble cultivator, the stubble cultivator shall be lowered to
the ground, the tractor’s brake shall be applied, the engine shall be turned
off and the ignition key shall be removed, in order to safeguard the stubble
cultivator against unintentional start-up.
•When performing maintenance work on a tool that has been lifted, the
lifted state of it must be secured with appropriate support structures.
•Remember to secure the supporting legs as well as the lifting arm with
lynch pins or bolts.
•Never leave the driver’s seat while the stubble cultivator is in operation.
•The driving speed must always be adjusted to the conditions.

TRIMAX 520
Page 11
•Only use the stubble cultivator if all safety devices have been mounted.
Defective safety devices must be replaced immediately.
Hydraulics
•No persons may be positioned within the operational radius of the
machinery when the hydraulic system has been activated, since there is a
risk of being crushed.
•Prior to any repair work on the hydraulics unit, the stubble cultivator must
be lowered to the ground, the pressure must be removed from the unit, the
engine must be switched off and the ignition key must be removed.
•Hydraulic connections must be cleaned thoroughly before connecting.
When connecting the hydraulic hoses to the tractor’s hydraulics, ensure that
the pressure has been removed from the hydraulic system.
•After repairs on the hydraulic system have been completed, all air must be
completely removed from the system.
•Check the hydraulic hoses regularly for defects such as tears, cracks, wear
or damage. Defective hoses must be replaced immediately. Never try to
localize a leak in the hydraulics using your hand. Utilize a piece of
cardboard instead. Avoid twisting the fittings when exchanging hoses. Use
2 wrenches to tighten and to loosen.
Fig. 4
•Avoid spilling oil on the ground. If this should happen, it should be
collected and safely disposed of immediately.
•Clean hands thoroughly after skin contact with oil and grease. Change out
of oil-soaked clothing immediately, as this can be harmful to the skin.
•Hydraulic oil that flies out under high pressure can penetrate through the
skin and cause serious injuries. Seek professional medical assistance
immediately in the event of any injury.

TRIMAX 520
Page 12
•The warranty for hydraulic hoses is limited to the exchange of hoses due to
defective materials or manufacturing defects. The warranty does not apply
forwear and tear, friction, cuts, or hoses that have been squeezed.
Mounting
•There is a risk of crushing when carrying out mounting. Standing between
the stubble cultivator and the tractor or between parts being connected is
not allowed.
Maintenance and repair
•The stubble cultivator must be properly supported or unfolded while
undertaking all kinds of repair and maintenance work, the tractor and
stubble cultivator must have their brakes properly activated, the engine
must have been turned off and the ignition key removed.
•Tighten all screw fittings after a few hours of use. All screw fittings must
be checked at regular intervals and tightened when necessary.Cotter pins
and bolts should be checked to avoid breakdowns.
•Use only your own tools and use sturdy gloves, safety shoes and safety
goggles.
•Oil, grease and filters must be disposed of and in accordance with the
applicable environmental legislation.
Driving on roads
•When driving on public roads, all safety arrangements and warnings
required by law must be installed and tested. The driver is responsible for
correct use of lights and traffic signs in accordance with traffic laws.
•Out of a regard for the dimensions of the stubble cultivator, the driver must
enquire with the traffic authorities to ensure that it may be transported on
public roads.
•When transporting the stubble cultivator, care must be taken not to exceed
the total weight and axle load of the tractor and that the load on the front
axle is no less than 20 percent of the tractor’s overall weight. If that is the
case, use front weights on the tractor.
Correct use
•Compliance with the manufacturer’s operating, maintenance and repair
instructions, as well as the exclusive use of original spare parts is included
in the correct use of the stubble cultivator.
•The stubble cultivator may only be used, maintained and repaired by people
who are familiar with the machine and who are aware of the dangers that
can arise.
•The manufacturer is not liable for damage caused by changes to the stubble
cultivator, carried out without the manufacturer’s prior permission.

TRIMAX 520
Page 13
Furthermore, the manufacturer is not liable for any damage that results
from incorrect use. Responsibility for this rests solely with the user.
•No extra weight may be installed on the stubble cultivator.

Delivery The stubble cultivator is delivered fully assembled, on a truck. In connection
with export it may happen that the machine is partially disassembled.
If the stubble cultivator is to be lifted, it is our recommendation to hitch with
straps in the middle, so that the stubble cultivator gets to hang in a balanced
position.

Use
TRIMAX is a heavy duty stubble cultivator, used for the mulching of stubble
and plant residue. Due to the large ground clearance, large amounts of plant
material can be mulched.
Fig. 6
TRIMAX is constructed so that a complete cut can be achieved, so that the
growth of crop as well as weeds is interrupted. The shape of the tines causes
soil and plant residue to be flung into the air and mixed in a uniform mass.
TRIMAX consists of a three bullet harrow, with a row of angled plates
mounted behind it, so that the plates even out and finely part the material just
behind the tines of the harrow. At the very back, the flat steel crumbler is
mounted. It controls the working depth and at the same time it crushes the
clods, packs the materials and evens out the layer. Their follower is equipped
with 60 cm t-rings.
Benefits from the use of TRIMAX 520
The TRIMAX 520´s benefits consist of:
•Precise setting of depth between 4 and 30 cm.
•No weight carrying wheels which may cause uneven packing in the field.
•Complete cut, reducing the need for further cross-driving.
•Uniform mixing up of plant residue.
•Preserves the moisture in the soil.

TRIMAX 520
Page 17
TRIMAX is particularly suited for work on the upper layers of soil, where the biggest turnover of
plant materials happens. Therefore, TRIMAX is an efficient tool to include in a strategy for reduced
soil treatment, since TRIMAX can provide a full cut of the field with just one drive through,
including a uniform mixing up of plant residue and the microorganisms in the soil. In order to
preserve the moisture in the soil and to optimize the micro-climate for the organisms in the soil, the
soil treatment is finished with a tight packing step.
Limitations in use
The following describes what the machine may/must not be used for:
•The machine may only be used for tilling land containing stubble and grass in agricultural areas
that have been cultivated. Those areas to be tilled must have been subject to normal agricultural
maintenance, i.e. without significant bumps or holes.
•The machine may only be used after first being attached to an agricultural tractor, by way of
connection to the rear 3-point hitch.
•The machine can work at a maximum speed of 12 km/h. The speed shall, however, always be
adjusted to the nature of the area.
•When undertaking a turn in the headland, the machine should be lifted from the ground to
prevent unnecessary wear and tear.
Any other use of the machine, which does not fulfil the aforementioned conditions, will be
considered unauthorised use, and will therefore be in breach of the manufacturer’s warranty.

Preparation of the tractor
The ballast of the tractor
When mounting the appliance, it is absolutely necessary that the highest degree of stability between
appliance and tractor is achieved –this can be ensured by using ballast, in order to counterbalance
some of the weight of the mounted appliance.
Front weights
May be necessary when mounting appliances behind the tractor, in order to place some of the total
weight of the machine on the front axle. This ensures stable road transportation and reduces the
“jumping” of the tractor during field work.
Factors which influence the stability
•The centre of gravity for the tractor/appliance/machine combination.
•The geometric conditions, such as the exact location of the appliance and the ballast.
•Weight, track width and the axle distance of the tractor.
•Acceleration, braking, turning and the relative location of the appliance during those
manoeuvres.
•The nature of the terrain, is it hilly, what type of underlay and the condition of the underlay.
•The flexibility of the mounted appliance.
•Pay special attention to the fact that on articulated tractors the balance is shifted, according to
how sharp a turn may be.
Suggestions for improved stability
•Increasing the track width; a tractor with a greater track width has more stability.
•Front weights.
NOTE: The suggestions mentioned above are purely a guidance with regards to stability, they are
not meant for guidance when it comes to the power of the tractor. It is recommended that you
contact your tractor manufacturer or your local dealer for specific guidance regarding this. At the
same time, you should contact a tire specialist for advice regarding tire pressure etc., so that all
settings will get to be compatible with the type of appliance that you wish to mount.
