duces the danger of accident.
5. All hydraulic hoses must be checked for their
operational safety by a skilled person before the
first operation of the machine.
6. Check hydraulic hoses regularly. . In case of
damage or ageing replace the hydraulic hoses!
The replacement hoses must correspond to the
technical demands of the implement manufac-
turer.
7. The period of use of any hose circuit should not
exceed six years including a possible storing pe-
riod of two years maximum. Also when stored
and used properly hoses and hose circuits do
age. Therefore their longevity and period of use
is limited. Deviations from the above may be ac-
cepted by the Health- and Safety Authorities de-
pending on the experience they have had and
the danger potential. For hoses and hose cir-
cuits made of thermoplasts other guide lines
may prevail.
8. Before starting to do repair work to the hydraulic
system release the pressure and stop tractor
engine.
9. When searching for leaks appropriate aids
should be used because of the danger of injury.

3. In transport position always take care for a suffi-
cient lateral locking of the tractor’s three-point.
4. In transport position danger of injury from pro-
truding discs .
5. During transport the valve on the draw bar must
be in the "end position", the swivelling hydraulic
must not be actuated.
6. The release ropes for quick coupler should hang
freely and in the low position must not release
the quick coupling by themselves.
7. The transport width of 3 m may not be ex-
ceeded.
8. For implements of more than 3 m transport
width, your national traffic law will be binding.
9. Tractor and implement must correspond to your
national traffic regulations.
10. Check and attach the transport equipment, as
e.g. traffic lights, warning plates and guards.
11. When transporting mounted implements the traf-
fic lights of the tractor must not be hidden. Oth-
erwise an additional traffic light kit should be fit-
ted. Your national traffic regulations will be
binding. The vehicle owner and the operator are
responsible for adhering to the legal traffic rules.
12. Check traffic lights for function.
13. Attach red-white striped warning plates to the
front and to the rear of trailed implements.
14. Apply warning plates according to DIN 11030 or
parking plates on the r.h. and l.h. side at the
front and at the rear.
15. The space between upper edge of the warning
plate and the road should not exceed 1.50 m.
Attach the warning plate with a maximum dis-
tance of 10 cm from the implement outer edge.
16. The maximum possible slope tilting (in transport
position) is 20 %. The maximum possible slope
tilting in operational position is equal to that of
the tractor. Do not fold in and out the roller
frame on slopes or undulated terrain.
17. During transport on public roads, especially
when driving in bends, take wide load of the im-
plement into account and keep a safe distance
of 1 m to other vehicles and to the edge of the
road.
18. Backing up with the implement in transport posi-
tion is only allowed with an additional person.

Description 13
Taurus 4000/3000 DB3070 06.02
3. Description of product
The disc harrow Taurus 4000/3000 (Fig. 3) is suit-
able for the use in minimum soil tillage on medium
and heavier soils.
The X-Pack formation of the disc gangs is used to
avoid any side forces on the tractor. (Fig. 4). Due to
the staggered arrangement of the discs in the cen-
tre the soil is moved across the entire working
width.
The depth control is provided by the rear consolidat-
ing roller. The adjustment of the working depth is
done by repositioning $0$=21(-eccentric
depth pin. The optimum reconsolidation of the soil
can be matched to varying soil conditions by a
choice of different rear rollers.
Cutting and mixing achieved in all working depths
by the infinitely variable gang angle adjustment. The
ø 660 mm discs with a load of up to 120 kg/disc
positively maintain the working depth even in heavy
soils and difficult conditions.
One disc gang consists of six to nine discs (incl.
smaller side discs) with two large bearings. The
centre shaft is a square of 40 x 40 mm made from
spring steel. The standard execution provides scal-
loped discs at the front and plain discs at the rear
with smaller outer discs to avoid ridge forming.
Scrapers on every disc ensure a blockage-free op-
eration.
At high operational speeds the side plates provide a
limitation of the soil flow (special option).
The cutting angle adjustment, mechanic or hydrau-
lic, allows an infinitely variable setting of the disc
angle. The cutting angle of the front and rear disc
gangs can be set individually via two hydraulic con-
trol valves. For an optimum operational perform-
ance the front cutting angle should be set shallower
and the rear one steeper.
The transport wheels are hydraulically lifted during
operation to prevent any wheel tracks being left on
the worked ground.

- Take the guard canvass from the retainer un-
derneath the rear of the frame and attach to
the disc gangs by using tension rubber bands
(Fig. 6).

When driving on public roads with
lifted implement the control lever has
to be locked against unintended lower-
ing.

7.1 Adjustment of the cutting angle
The usual adjustment for the traction force, the op-
erational speed and the operational efficiency is:
- 18º on the scalloped disc gangs in the front,
- 15º on the rear plain disc gangs.
7.1.1
Hydraulic adjustment of the cutting
angle
Proceed as follows to change the cutting angle ad-
justment:
- Implement is in raised position.
-
Adjust double acting hydraulic ram via the tractor
control spool valve.
-
Hydraulically swivel the front disc gang pair by
actuating the valve pulling rope and observe the
front setting scale (Fig. 7/1).
- Hydraulically swivel the rear disc gang pair with-
out actuating the valve pulling rope and obser
ve
the rear setting scale.

Staying underneath a raised, unsecured
implement is prohibited. Keep away
from the swivel area of the disc gangs
(except for the operator).
F
The hydraulic cutting angle adjustment
allows changing the cutting angle during
operation in the field.
7.1.2
Mechanic adjustment of the cutting
angle
Procedure for changing the cutting angle adjustment:
- Implement is in the raised position.
-
Use the front upper links to manually turn the
front pair of disc gang longer or shorter (Fig. 8
/1)
and observe the front setting scale.
- Use the rear u
pper links to manually turn the rear
pair of disc gang longer or shorter (Fig. 8
/1) and
observe the front setting scale.

7.2 Working depth
a
The implement is in the raised position
The height adjustable rear mounted roller provides
the accurate depth guidance. The resetting and/or
twisting of the so-
called eccentric pins allow a nearly
infinitely variable setting of the working depth.
Reset the eccentric pin (Fig. 9/1) upwards to in-
crease the working depth of the discs on the lowered
implement.
Reset the eccentric pin downwards to reduce the
working depth of the discs on the lowered imple-
ment.
The fine tuning of the working de
pth is achieved by
twisting the eccentric pin from position 1 (shallow) up
to position 4 (deep).
- Slacken clip pin.
-
Insert the eccentric pin higher/lower and/or twist
it.
- Retighten clip pin.
F
The chosen setting holes must coin-
cide. The stops of the e
ccentric pins
should also coincide regarding their
numbers.
