Employment
DINCO is a heavy-duty cultivator, which has been designed to work down
stubble and crop residues. Owing to the large ground clearance and the
distance between the tines great amounts of crop residues can be worked down.
Dinco has been designed to obtain complete cutting by which the growth of
both crop and weeds is stopped. The shape of the tines causes the top soil and
crop residues to be thrown in the air and mixed into a homogeneous mass.
Dinco consists of a harrow with two rows of tines to which an arm with
inclined discs has been mounted to level the tracks after the cultivating tines.
At the very back you will find the rear roller which is used to control the
working depth and to crush clods and level the surface. The rear roller comes
as a packer roller or with 60 cm. t-rings.
As extras a 400 mm. crumbler can be fitted behind the compulsory rear roller.
Moreover, a seeddrill can be fitted to the Dinco for direct sowing of catch
crops.
Advantages of using Dinco
The advantages of Dinco are:
·Exact adjustment of working depth between 4-20 cm.
·No supporting wheels causing compaction in the field.
·Complete cutting thus making less drives in the field necessary.
·Homogeneous mixing of crop residues.
·Keeps the soil moist.
Dinco is particularly suitable for working in the topsoil where the majority of
plant transformation takes place. For that reason Dinco is an effective tool in a
minimum tillage-strategy as Dinco with only one drive provides a complete
cutting of the field and a homogeneous mixing of crop residues and micro-
organisms in the soil. To keep the soil moist and thereby optimise the
microclimate for the organisms, the working of the soil is completed by a
packing.
ÑDinco is only to be used in ordinary field work. Dinco should not be used in
deforestation or the breaking up of old roads, paving stones or the like. If in
doubt, please contact your Dinco-agent or DAL-BO.
ÑDinco is not to be used as a crane, a pile driver, a hydraulic press or the like.
ÑWhen operating the Dinco you must be seated on the tractor.
ÑPersons are not to stay on the Dinco while driving.

Dinco
Page 8
ÑWhen using Dinco on stony soil some noise may be experienced. However, the
level of noise is far below the danger level for the tractor driver.
ÑDust formation may arise when driving under very dry conditions. It is
therefore recommended that doors and windows of the tractor are kept closed
while driving or that a dust mask is used.

Dinco

Connecting and disconnecting
Dinco is constructed according to the DS/ISO 730-1 category II and III. If the
lift construction on the tractor is not designed for this, please contact your Dal-
bo agent.
Connecting
First mount the lift arm with the lift pins. Then mount the levelling bar. Adjust
the levelling bar so that the frame is in a horizontal position.
ÑPlease remember to secure the lift arms and the levelling bar connections with
split pins.
Hydraulics
Depending on the type of Dinco different requirements for hydraulic services
on the tractor are necessary.
·Hydraulically folding models require a double-acting service.
·Models with NSH require a single-acting service (NSH=Non Stop Hydraulic).
(Hydraulically folding models with NSH require only double-acting service
as the hydraulic hose for NSH can be dismounted after adjusting (see
”Adjustment”), whereupon hoses for folding and unfolding can be
connected to the double-acting service).
Connect the hydraulic hoses to the double/single-acting 1/2´´ socket situated
near the lift.
Disconnecting
Disconnecting is done in reverse order than connecting. Please remember to
ease the pressure on the connection hose before the hydraulic hose is
disconnected. Furthermore the ball plug valve for hydraulic stone releasers
should be closed (see fig. 4).
Handling without three-point hitches
If moving Dinco without the use of three-point hitches, it is recommended to
use straps in the main frame to keep Dinco in balance.

Adjustment
Dinco has been adjusted from the manufacturer. A fine adjustment is, however,
always necessary before putting the machine into use. Several possible
adjustments make your Dinco more versatile thus making the optimal
utilisation of the machine possible.
Adjustment of depth
Cultivation depth is controlled by the rear roller in the form of a packer roller
or a t-ring rear roller.
The working depth of the tines is adjusted with pegs in the hole plate (A). The
upper peg (B) determines the working depth while the lower peg (C) is a
supporting peg, which carries the rear roller when the implement is lifted.
When changing working depth it may be necessary to readjust the levelling bar
as the frame should always be level during operation.
Fig. 1
Deeper tillage
Deeper tillage can be obtained by lifting the implement from the ground so the
lift arm (D) does not press against the upper peg (B). In that way the peg can be
removed from the hole plate and be placed in a higher hole. The lower peg (C)
is similarly moved up so that the support is as close to the lift arm (D) as
possible.
When Dinco has been adjusted to deeper tillage it may be necessary to drive
the tines in the soil for a while (or support the rear roller) in order to add
pressure to the rear roller. After this the lower peg (C) can easily be fitted in to
the hole closest to the lift arm (D).
A
B
C
D

Dinco
Page 11
Level tillage
More level tillage can be obtained by moving the pegs down. By this the
cultivating frame and thereby the tines are lifted to a more level tillage. It may
be necessary to drive the cultivating tines in the soil in order to loosen the
lower peg (C, fig. 1). After having placed the lower peg (C) in a lower hole
Dinco must be lifted and the upper peg (B) placed as close to the lift arm (D) as
possible.
Depth adjustment of discs
The correct adjustment of the discs leaves the field level with no visible traces
of the harrow tines. Fine adjustment of the discs is done with the spindle (A)
and not until actually in the field. Discs must be adjusted to work the top soil,
so that a suitable quantity of earth is thrown back after the harrow tine.
Fig. 2
The angle of the tine
Adjusting the penetration angle in two different positions (A, B) makes it
possible to have a soil-searching tine all the time. From the manufacturer the
shank (C) is set in its most soil-searching position in the back hole (A).
Fig. 3
A
C
A
B

Dinco
Page 12
On dry and hard soil use the most soil-searching/aggressive adjustment (A, fig.
3). On light and moist soil use the front hole (B). Due to wear and tractive
force the penetration angle should not be larger than necessary to obtain a
satisfactory outcome.
Non Stop Hydraulic (NSH)
NSH-models are designed with hydraulic stone releasers. Adjust working
pressure by connecting the hydraulic hose to the single-acting service on the
tractor. Then open the shut off valve (A). During adjustment the pressure can
be read on the manometer (B) at all times. When adjustment is done close the
shut off valve and the hydraulic hose can be disconnected from the tractor. If
the shut off valve is not closed, oil will slowly ooze back to the tractor and
pressure on the system will fall.
Fig. 4
ÑThe NSH-system should only be pressurised to max. 100 bar due to the danger
of overloading the implement and the tractor.
Accumulator
Dinco with NSH-system is equipped with an accumulator which functions as a
buffer for releasing tines and enables the hydraulic stone releaser to get rid of
excessive oil. The accumulator is set at 60 bar which means that it works its
best at a system pressure of 70 bar, at which level the container begins to fill
up.
Hydraulically folding models
On hydraulically folding models adjust the side sections with the bolts (A) so
that the frames on the side sections and the main frame are level (An
adjustment bolt can be found on each side of the main frame).

Driving and operating
The right operation is important to obtain the optimal utilisation of your Dinco.
This applies to fieldwork as well as security.
ÑEach day before work is started check that no nuts or bolts are loose and
that all splits pins are intact.
ÑWhen turning or reversing Dinco should be lifted.
ÑNo extra weight should be mounted on the Dinco as the implement is not
designed for it.
ÑWhen unfolding no persons are allowed within the radius of action of the
implement.
ÑWhen driving on public road the hydraulically folding model should be
fixed in transport position.
ÑDuring transport any side discs should be folded.
The shares give a heavy cultivation. Despite the heavy cultivation the field
should be left even and with no banks of any kind. This requires a correct
adjustment of the implement (see ”Adjustment” page 6).
Working depth
Dinco can be adjusted to very light tillage in a depth of 4 to 5 cm. This is
possible only because the shape of the tine leaves the field level and
completely cut.
Fig. 6
Dinco should be adjusted so that it is carried by the rear roller. The handle for
the tractor lift must be lowered completely when driving in the field so that the
lift is floating and can move with the terrain. The cultivation depth will thus be
controlled by the rear roller in the back and by the levelling bar in the front.
When changing the working depth a readjustment of the discs is necessary. The
discs are designed to work in the topsoil, however, they do not perform any
real tillage except levelling out the field after the tines, so that a suitable
quantity of earth is thrown back after the harrow tine.

Dinco
Page 14
On the models for the German market side discs for levelling the outside of the
outermost tine are standard equipment whereas models for other markets are
equipped with covering discs on the outermost tines. Side discs are therefore
considered extras on markets other than the German (see ”Extras, Side discs”).
Folding and unfolding
There is no transport lock on the folding models as the side sections move
right in over the main frame where they will rest on the supporting structure
(A).
Unfolding is done by activating the hydraulic handle in the unfolding position.
It is important that the side sections are completely unfolded and press against
the adjustment bolts (fig. 5) as the main frame and the side sections should be a
rigid unit.
Fig. 7
ÑBefore folding the 380-model any side discs must be folded to avoid collision.
Speed
To obtain optimal tillage a working speed of 6-7 mph (10-12 kph) is
recommended. However, one should always drive according to conditions.
Please note that wear is heavily increased when speed is increased. Shares may
be lost or damaged when driving to fast under unfavourable conditions.
When driving at high speed - especially under dry conditions -wear on the
tines will increase considerably.
Power
Dinco is a power-demanding implement and it is recommended to have a
tractor with a sufficient power surplus so that working speed can be maintained
when driving uphill. In this way the field gets a uniform treatment which may
be important later on.

Hydraulic stone breakaway
Fig. 8
NSH-models are designed with hydraulic stone breakaway –an
advantage when driving under very stony soil conditions. When
hitting a buried stone the tine concerned will breakaway so that the
stone can pass through the cultivator. When the stone has passed the
tine will automatically swing back to working position with no stops
necessary.
Under normal conditions a system pressure of 60 bar is
recommended, however, in extreme cases if the soil is very hard the
system pressure can be increased to max. 100 bar.
System pressure above 100 bar is NOT recommended as a too heavy
filling of the accumulator will be the result and consequently the
tines will not breakaway sufficiently.
Mechanical stone breakaway
Shearbolt
Fig. 9
The standard model D is designed with mechanical stone breakaway
in the form of shearbolts, but can easily be converted to hydraulic
stone breakaway (NSH) (see “Replacement and Repairs”).
Tine overload protection by means of shearbolts is used in fields
with only few buried stones. When hitting a buried stone the bolt
will shear off and the tine break back. In this way the stone can pass
through the cultivator without overloading the implement or the
tractor.
It is necessary to stop the tractor and change the shearbolt. Remove
the broken shearbolt and tip the tine back into place and fit a new
bolt 16x80mm.
Inclined discs have been secured with a 10x70mm shearbolts. The bolt shear
off when overloaded and stones can pass.
ÑNever use fingers to remove broken shearbolts but use a screwdriver or the
like.
ÑWhen changing a shearbolt Dinco must be lowered and rest on the foundation.
If the implement is lifted a strong support of the main frame must be provided.

Dinco
Page 16
Maintenance
Proper maintenance lengthens the life span of the Dinco and thus secures
optimal utilisation of the implement. For that reason grease nipples have been
placed where the most wear happens.
All nuts and bolts should be tightened up after the first day. Pins and bolts
should be checked to avoid damage.
Lubrication
Depending on the model a different number of lubrications points exists which
need lubrication after 50 hours work. The lubricating nipples by the tines,
however, should be lubricated daily.
·(A) Roller bearings (50-hour-lubrication interval)
·(B) Disc bearings (50-hour-lubrication interval)
·(C) Spindle (lubricate as required)
·(D) Lubricating nipple for the pin in the bottom of the cylinder (daily)
·(E) Lubricating nipple for the pin in the eye of the cylinder (daily)
·(F) Lubricating nipple for the pin in the tine holding plate (daily)

Safety
ÑIt is very dangerous to stay under Dinco when it is lifted without proper
support. At the same time the tractor should be properly braked and the engine
switched off.

ÑDefective hydraulic hoses should be replaced immediately. Defects on hoses
may cause injury to persons or damage to the implement.
ÑAll bolted connections should be checked often and tightened when needed.
ÑAfter working with oil, hands should be carefully cleaned. Oil stained clothes
should be removed immediately as it may cause damage to the skin.
Wearing Parts
The points on Dinco are reversible and should be turned before the shank to
which the points have been clamped starts to wear down (see ”Replacement
and repairs” page 19). Points with covering discs on the outermost tines should
be changed from right to left when turning the points so that the covering discs
are placed on the outside.
Wings should be changed when they are worn down to the extent that the work
result is no longer satisfactory or before the shank starts to wear down.
Other things
Avoid spilling oil on the ground. Should it happen anyway, gather it together
and deliver it for destruction.
When parked under damp conditions for a longer period piston rods should be
lubricated in oil or fat to avoid corrosion.
Cleaning and checking
When the season is over, the machine should be cleaned for dirt and moist
attracting material. This facilitates later services and repairs.

Dinco
Page 18
Accessories
Various forms of accessories for Dinco exist, e.g. hydraulic stone breakaway
(NSH), crumblers and side discs. Other accessories are lights and seeddrills.
Mounting of NSH
Mounting the NSH stone release system on a Dinco with mechanical stone
release (shearbolts) is easily done as Dinco has been prepared for this
conversion.
Fig. 11
Mechanical stone breakaway NSH stone breakaway
1. Support Dinco as described in ”Replacement and Repairs” to avoid danger
of personal injury. Tines should be free of the ground in order to be able to
move them freely.
2. Remove the splitpins (A) and pull out the pins. Now the mechanical
shearbolt cylinders can be removed.
3. Then mount the hydraulic stone breakaway instead with the same pins.
Please remember to remount the splitpins.
4. Mount the hydraulic hoses etc. according to the spare parts drawing.
Connect the hoses so that they do not lie flat against the frame. This will
extend their life span. Mount the accumulator so that the tines can break
back completely without colliding with the accumulator.
ÑPlease check that hoses are not in danger of being disconnected or squeezed.
Crumbler
The crumbler is mounted behind the rear roller and gives an extra working of
the field. The crumbler is designed as a roller with a smaller diameter than the
rear roller, which means a faster rotation and thereby a more effective crushing
of clods. At the same time the crumbler packs the topsoil to preserve the
moistness of the soil.
A

Dinco
Page 19
Mounting of accessories
Depending on the type of rear roller (packer roller or t-rings) two different
bearings for the crumbler exists.
Fig. 12
T-rings
The crumbler for the t-ring roller is mounted with 4 16x50 mm. bolts, which
are fitted in the flanges (A, fig. 12) at the very back of the bearings for the rear
roller. The adjustment bolts (A, fig. 13) should be screwed in completely to
facilitate the mounting. Fine adjustment of the crumbler is done on the basis
that the adjustment bolts have been screwed in completely.
Fig. 13
Packer roller
As packer rollers come with no scrapers bearings (B, fig. 13) should be
mounted before the crumbler can be mounted.
1. Mount the adjustment bolt (A) and screw it all the way in.
2. Mount the rotation stand (C, fig. 13) on the bearing (B, fig. 13), please
remember the washer and split pin.
3. Bolt the rotation stand to the bearing of the rear roller (D, fig. 13).
4. Mount the flange bearings loosely on the crumbler shaft
5. Roll the crumbler in between the bearings (B, fig. 13).
6. Bolt the flange bearings to the bearing.
7. Secure the pointed screws with Locktite and tighten them.

Page 20
Driving and adjusting
The crumbler is not designed to carry Dinco. Its only job is to crush, cultivate
and level after Dinco as the working depth is determined by the rear roller.
The crumbler should be working in the topsoil. The pressure is adjusted by the
bolts (A, fig. 13). If the bolts are loosened the pressure of the crumbler on the
ground will increase and if the bolts are tightened the pressure will decrease.
ÑThe crumbler should not be set to carry Dinco.
Side discs
To level the soil outside the outermost tines side discs can be mounted. The
side discs are inclined discs on arms, which can be swung outside the outer
tines. Side discs are most relevant in connection with sowing of catch crops
with Dinco seeddrill.
Fig. 14
ÑDuring transport side discs must be locked in transport position. It is important
that the plate is fixed with the pin in transport position to prevent the discs
from swinging out when driving (se fig. 15, B).
Mounting
The plate for the side discs is fixed with two bolts (A) through the frame.
Mount the shank with the discs on the arm so that the hollow side of the discs
turn inwards.
