ATTACHING TO THE TRACTOR
Preparations on the tractor
Wheels
- Air pressure in the tractor’s rear tyres when ploughing
should be 0.8 bar.
- Under difficult operating conditions additional wheel
weights can be advantageous. See the tractor
manufacturer’s operating manual also.
Ballast weight
Sufficient ballast weights are to be
stacked on the front of the tractor in
order to guarantee steering and braking
capabilities.
At least 20% of the tractor’s tare weight on
the front axle.
Lifting gear
- Left and right lifting struts (4) must be of equal length.
Adjust using adjusting device (3).
- If the lifting struts on the lower link can be pinned
variously, then select the back position (H). In so doing
the tractor’s hydraulic unit will not be heavily loaded.
- Position (2) the upper link (1) according to the tractor
manufacturer’s information.
Setting-up for transportation
- Fix the lower link with the struts (5) so that the attached
implement cannot swing out during transportation.
- The hydraulic’s operating lever must be secured against
lowering.
- Road transport not in “On-Land” position
Setting-up for ploughing
- Set the struts (5) so that the greatest possible sideways
swing range exists.
Hydraulic control on the lifting gear
Control position:
For mounting and dismounting the implement and for
transportation.
The control position is the normal setting for the lifting
gear hydraulics.
The mounted implement remains at the height (= position)
set by the servo-valve (ST).
Pull control, mix control:
Ploughing occurs with of one of the two operating modes.
See chapter „OPERATION“ for description.

1400_GB-ANBAU_983
ATTACHING TO THE TRACTOR GB
Attaching to the tractor
- Switch tractor’s hydraulics to control position.
- Attach implement to lower link and secure with linch
pin.
Note
The attaching frame can be positioned horizontally by
turning the tilt spindle (11).
Doing this enables an easier coupling to the lower link.
Then turn the tilt spindle (11) back. See chapter
„OPERATION“ also.
Pin upper link (1)
- Pin upper link (1) so that the attachment point (P1) on
the plough during operation is somewhat higher than
the attachment point (P2) on the tractor.
Securing lower link
If the tractor’s hydraulic control is to be steered over the
lower link, then the upper link should be positioned in
the slot (LL) on the attaching frame.
Securing upper link
If the tractor’s
hydraulic control is to
be triggered over the
upper link, then both
the (RL) borings on
the attaching frame
are to be used.
- Couple hydraulic hoses to the tractor.
Important advice:
Supportstand in the working position
1. Lock the bolt (1) into the hole of the stand plate.
2. Secure the supportstand with linch pin (K).
Insert pin only in the first hole.
Do not use holes in pos. 2 - 9
- otherwise support stand will be damaged when
turning plough
Lighting and Warning equipment
When travelling in fog, half-light or at night, protruding
parts are to be clearly indicated. Advice on the application
of warning signs, reflective
film or paint and lighting
units can be found in the
instructions for ancillary
equipment in supplement C.
PôTTINGER can supply
lighting units and warning signs upon request.

Removal from tractor
Hint: The shear points are hardened so when set down
onto hard surface (stone, concrete, etc.), risk of breaking
exists. Therefore lower the shear points onto a suitable
support (wooden board)!
- Turn plough frame to working position and park the
implement on stable and even ground
- Move the control
lever (ST) back and
forth several times
to reduce pressure
in the hydraulic
lines.
- Switch tractor’s
hydraulics to control
position.
- Disconnect hydraulic hoses from tractor.

OPERATION
Caution when driving into the field with
SERVO 35 and 45
Be advised!
Danger of material damage when driving
into the field - when the plough is still in
transport position (horizontal position)
and is therefore raised (distance A). The
spindle can be damaged in case of strong
vibrations.
Therefore transport the plough by
transport wheel or first turn plough into
working position.
Rotating the plough
Beware!
During plough rotation, nobody is allowed
within the swing range.
Operate the rotating unit only from the
tractor seat.
For the rotating process, the plough must
be lifted fully.
The rotating unit is equipped with double-acting cylinder
and integrated automatic reversing gear.
The automatic reversing gear enables the whole turning
procedure to be carried out through only one single
switch position on the control unit (ST). (Necessary oil
quantity: 40 - 50 l/min)

ST
Rotating process
The rotating process is performed in the same way with
the help of the single-acting or double-acting control
device.
For the single-acting control device you need a return
pipe on the tractor.
- Switch the control device (ST) to Lift (h).
(for the version with single-acting cylinder or memory
cylinder first you swivel in the frame), after turning you
swivel it back out. see chapter Variants.
The plough body is rotated with 180°.
- Switch the control device (ST) to Neutral (0).
After about 5 seconds, you can perform a new rotating
process.
Setting the plough inclination (11)
The plough should sit as vertical (90°) as possible to
the ground during ploughing. This position is obtained
by turning both spindles (11) as described below.
- Lift the plough 5 - 10 cm.
- Operate the control device (ST) briefly.
The plough frame rotates away from the stop spindle
(11).
- Set the inclination with the help of the spindle (11).
- Rotate the plough frame back to stop position.
- Continue ploughing and check whether the new setting
brings the plough bodies to approximately vertical
position (90°) to the ground.

OPERATION GB
Setting the plough on a tractor with
"Servomatic"
The setting technology "SERVOMATIC" adjusts plough
and tractor optimally to one another.
The following setting controls should be carried out in order.
Never reach into the crushing
danger zone as long as parts are still
moving.
Do not stand in the swinging
range of the implement.
1. Setting furrow width
- See chapter "PLOUGH PRESETTING"
2. Cutting width setting of the first plough body
(backfurrow)
The cutting width (S2) of the first plough body is set by
rotating the spindle (VF).
Cutting width (S1) too narrow
- Rotate spindle (VF) further.
Cutting width too wide
- Rotate spindle (VF) less.
Cutting width (S2) correct
- The spindle is set correctly.
See chapter "PLOUGH PRESETTING"
Hydraulic cutting width adjusting (SERVO PLUS)
Therefore an additional double-action control unit is
necessary on the tractor.
3. Set the drawing point (Z)
Setting correct
The drawing line (ZL) runs through the mid-point (M) of
the tractor’s rear axle. No side pull occurring on the tractor.
The plough is operating smoothly.
- Spindle (ZP) set correctly.
See chapter "PLOUGH PRESETTING"
Setting wrong
The drawing line does not run through the mid-point of the
tractor’s rear axle.
a.) When ploughing the tractor is pulled into the ploughed
area. This can only be compensated by steering in the
opposite direction.
- Rotate the spindle (ZP) further.
b.) When ploughing the tractor is pulled into the unploughed
area.
- Rotate the spindle (ZP) less.

OPERATION GB
Ploughing with adjusting hydraulics
Observe the following so that the adjusting hydraulics
operate correctly.
TD65/92/27

P2
- Pin the upper link (1) so that during operation the
connecting point on the plough (P1) is a little higher
than the connecting point (P2) on the tractor.
Pinning the upper link
LL, RL = Securing position for securing lower link.
RL = Securing position for securing upper link.
See chapter „ATTACHING TO THE TRACTOR“ also.
- During operation, the plough frame shall be placed
longitudinally, approximately in parallel to the field
surface.
- First, the working width is adjusted with the help of the
lifting device via the control valve (ST).
Changing ground resistance during ploughing,
depending on the model of the adjusting hydraulics,
is transmitted to the control valve via the upper link
(1) or the two lower links. The relevant impulse is then
converted causing the lifting gear to lift or lower.
One example: Upper link adjustment
The plough goes deeper into the ground.
Thus the pressure on the control valve becomes higher
through the upper link.
As a result, the control valve is switched on Lift until
the set working depth is reached again.
Note:
Also observe the operating instructions of the tractor
manufacturer.
Hydraulic cutting width adjustment
(SERVO PLUS)
The adjusting device is operated with the help of a
hydraulic cylinder. Therefore an additional double-action
control unit is necessary on the tractor.
You can also perform a stepless adjustment of the cutting
width during ploughing. The drawing line position is not
influenced by this (see "Setting the drawing point (Z)").
Advantages:
- Exact ploughing on the edges.
- Ploughing around obstacles (masts, trees etc.).

OPERATION
ON-LAND Ploughing
What does "ON-LAND-Ploughing" mean?
No tractor wheels in the furrows
- All wheels travel on unploughed ground.
Advantages of an "ON-LAND-Plough"
Ground care with "ON-LAND" ploughing.
No tractor wheels in furrows to compress and knead the
ground. Less tractor wheel slippage as with conventional
ploughing in wet conditions.
Greater swing range
This makes even travelling on unploughed ground with
dual wheels possible.
Boundary ploughing possibility
To swing the plough away from ground already ploughed
(antiON-LAND position). This enables accurate
ploughing right up to a boundary.
• Conventional Ploughing
The plough can be centred behind the tractor =
conventional ploughing with wheels in the furrows.
KP = conventional ploughing
OP = "ON-LAND" ploughing
Conventional ploughing
Ploughing with wheels in the furrows

SERVO NOVA
Fully automatic "Non-stop" overload
safety
For grounds that are difficult to plough, with stones or
other foreign bodies, it is recommended to use the fully
automatic overload safety.
With the SERVO-NOVA plough, every plough body
is secured individually against deteriorating by hydro-
mechanical means.
When driving over obstacle, the plough body can swing
to either side. There is no need to stop the tractor. The
plough body swings back to working position by itself.
In addition to the fully automatic "Non-stop" overload
safety, all plough bodies are protected by a shearbolt.
See chapter "OVERLOAD SAFETY“ for a description.
Setting range
• The triggering force of the overload safety can be
adjusted function of the various ground types.
Normal setting
- The pressure on the hydraulic cylinders (40) must be
approx. 10 bar higher than the nitrogen pressure in the
gas tank (43).
Nitrogen pressure in the gas tank (43) (factory
setting)
80 bar
Setting range for the pressure in the hydraulic
cylinders (40)
90 to 160 bar
If you see during practical operation that the overload
safety triggers too often, you can increase the pressure(*
in the hydraulic cylinders with the accompanying top-up
device (42) (see table).

drops.
- Operate the control valve on tractor until the gauge
indicates the target pressure. Then close the shut-off
valve (position A).
Beware!
The stopcock must always be closed during
ploughing (position A).
- Depressurise the top-up pipe by means of the control
valve.

1600_GB-NOVA_984
SERVO NOVA GB
Gas tank (43):
The pressure in the gas tank can also be changed.
Reducing or increasing the gas pressure in the tank
depends on the various types of ground.
In case of very light ground, you can reduce the gas
pressure to a certain extent.
Be advised!
No welding, soldering or mechanical work
may be performed on the gas container.
Changing the pressure in the gas tank
This operation may be performed only
by the customer service or a special-
ised workshop.
To reduce or increase the preload
pressure, you need a special filling
and verification device.
1. Release pressure:
a) Take out the plastic cover.
- Take out the lead mould plug (if available) in the gas
filling plug (44) with the help of a sharp tool.
b) Loosen the gas filling plug (44) only slightly.
c) Screw on the filling and verification device.
d) Open the evacuation cock on the filling device slightly.
Let out the nitrogen (N) slowly until the gauge has
reached the target pressure.
e) Close the evacuation cock, take out the filling device,
tighten the gas filling plug and put back the lead mould
plug (if provided).
2. Increase pressure:
For tank filling only use nitrogen (N), no
oxygen (danger of explosion).
f) Connect the filling device onto the nitrogen bottle.
g) Take out the plastic cap.
- Take out the lead mould plug (if available) in the gas
filling plug (44) with the help of a sharp tool.
- Loosen the gas filling plug (44) only slightly.
- Screw on the filling and verification device.
h) Screw the verification device onto the nitrogen bottle.
i) Open the evacuation cock on the filling device slightly
and fill with nitrogen until the gauge reads the target
pressure.
k) Close evacuation cock, take out the filling device, tighten
the gas filling plug and put back in the lead mould plug
(if available).
Note
All gas accumulators show a slight pressure drop after a
certain period of time, according to "HYDAC" factory
specifications.
The gas loss amounts to approx. 2-3 % pa.
It is recommended to check and if necessary correct tank
pressure after 4-5 years.

Basic setting of the ploughing component
Checks must be made in the following order after replacing worn out parts:
1. Stand the plough on even ground.
2. The gap (A) between plough and share cutting edge must be the same for all ploughing components.
3. Check the gap (B1) on the last ploughing component.
B1 = 0 - 5 mm for ploughing components* of the type W, UWS
10 - 20 mm for ploughing components* of the type UW, UWS, WSS
4. Set the same measurement for gap (B) as for B1.
* The type of ploughing component is shown clearly on the manufacturer’s plate.
Setting the ploughing component tilt
If the plough is not penetrating the ground correctly, an
improvement can be obtained by turning the eccentric bush.
The blade point in the area „S“ is set either higher or
lower depending upon the position of the eccentric bush
(A or B).
Retighten screws after resetting.
On some models a catch plate is fitted instead of an
eccentric bush.
