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.
Setting-up for ploughing

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.
External measurement
The outside rear wheel measurement (A2) should not be
greater than 2,5 m. More than 2,5 m constricts manoeuvrability.
Wheel gap
Wheel gap (A1) should be between 1,3 m - 1,5 m.
Side pull (see also "Setting the drawing point " on page 9)

PRESETTING THE PLOUGH
- 11 -
Before driving to the field
Set cutting width
- Loosen front hexagonal screw (SK).
- Remove rear hexagonal screw.
- Swivel anchoring console until the required
cutting width is obtained and the hexagonal
screw fits into one of the borings (1, 2, 3,
4, 5).
- Retighten hexagonal screws.
Setting the drawing point (Z)
•In this matter please also refer to the chapter "Attaching to
the tractor".
Correct setting
The drawing line (ZL) runs through the mid-point (M) of the
tractor’s rear axle. No side pull arises from the tractor.
The plough is easy to pull.
Incorrect setting
The drawing line does not run through the mid-point of the
tractor’s rear axle. Tractor is drawn into already ploughed
area during ploughing.
Remedy: Set both struts (5) so that the lower link can move
sideways freely.
• Set the movement
range left and right
equally.
Setting furrow width of first ploughing
component (backfurrow)
The furrow with (S2) of the
first ploughing component
is set by turning the
spindle (VF).
Furrow width (S1) to narrow
- turn spindle (VF) longer
Furrow width (S2) to wide
- turn spindle (VF) shorter
Weight the front axle sufficiently
•if the tractor's front axle is insufficiently weighted during
operation
- insert bolts into lower hole (B2)
- secure bolts correctly
•Normal position of bolt is at the top (B1)
- through this the rear axle carries more weight
- less rear driving wheel slippage
Attaching rail
The attaching rail is installed
in the upper position of the
slot. The lower position has
no influence on the plough's
function.
•Therefor the attaching rail
does not need to be installed in
any other position.
Setting the ploughing depth
- Draw hydraulic cylinder (8a) out
slightly
- Set ploughing depth with the
adjusting sleeve (8).

Setting the plough gradient (6a)
When ploughing, the ploughing components should be
almost vertical (90°) to the ground. This positon is obtained by
turning both the adjusting screws (6a), as described below.
- Raise plough front a few cm
using tractor's lifting gear
and then lower again.
This relieves the adjusting screws
(6a).
- Set gradient with adjusting screws (6a).

General maintenance advice
In order to keep the implement in good condition even after a long
service life, please observe the following points:
Safety hints:
•Turn engine off when
adjustment, service and
repair work is to be done.
•Do not work under the
machine without safe
support.
- Retighten all screws after the first hours of operation.
During operating time
- Check all screws occasionally and retighten if necessary.
W = Grease the greasing points weekly.
J = Grease at least twice per season.
At the same time oil joints and adjusting spindles also.
Expendable parts
- Replace worn out expendable parts in time to prevent all stress-
bearing parts from becoming damaged.
Tyre pressure
max. 2,4 bar
- Pay attention to the correct tyre
pressure!
Check tyre pressure regularly!
Danger of bursting exist when inflating
or when tyre pressure is too great!
Cleaning the machine parts
Take note!
Do not use a high pressure cleaner to clean bearings or hydraulic
parts.
- Danger of rust formation!
- Lubricate the machine after cleaning and carry out a short trial run.
- Cleaning with too much pressure can damage the paintwork.
Parking in the open
When parking in the open for
longer periods, clean plunger rods
and then grease.
Winter storage
- Thoroughly clean the machine
before storing.
- Store the machine where it is weather protected.
- Protect exposed parts against rusting.
- Grease all greasing points
Hydraulic unit
- Check hydraulic hoses regularly for damage.
Immediately replace porous or damaged hydraulic hoses.
Beware: Danger of infection! Where there are dfects in the hydraulic
unit, do not touch areas of leakage.

MAINTENANCE AND SERVICE
- 17 -
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 blade cutting edege 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.
See
"Basic setting of the ploughing component"
also.
(943) 9500 GB ZUSÄTZE
GB
ADDITIONAL DEVICES
- 18 -
(* Beware! Danger of injury on the cutting edges.
Setting the disk coulter
(*
•Set the cutting depth of the disk coulter at a gap of 5 cm to the
ploughing blade tip.
•The lengthwise fitting position is preselected by moving the carrier on
the console.
Further fitting positions arise by swivelling the eccentric (50) 180°.
•The lateral gap to the
ploughing blade tip
should be 2 - 3 cm. It
is set by swiveling the
eccentric (50).
Spring loaded disk coulter
(*
- This disk coulter can be fitted to all SERVO NOVA ploughs with a
frame height from 72 cm.
Pre-ploughing implements:
Maize skimmer, Manure skimmer
These implements are designed to incorporate surface trash
straw or manure in the soil.
•Set the working depth to 1/3 of the total working depth.
•The lengthwise fitting position should lie over or behind the
ploughing blade tip. Where there is a lot of surface growth, or
when ploughing in straw, the pre-ploughing implements should
be set back as far as possible.
Leg deflector (60)
Leg deflector, which are fitted to the ploughing
component, serve to bend the stalks less
when ploughing in straw enabling them to slide
off better.
Trashboards (61)
For ploughing in manure or other fertilizers.
•Trashboards for ploughing components of the
type UW, W, WSS.
These implements can be used instead of
manure mulchers (see above) but are not very
effective with shallow working depths.
Knife coulter (62)

Fully automatic „Nonstop“ overload safety
The fully automatic overload safety is recommended for soils which are
difficult to plough e.g. soil with stones or other foreign bodies.
Every ploughing component is hydromechanically safeguarded against
damage on the SERVO-NOVA plough.
When driving over an obstacle the ploughing body swings out to either side
and then swings automatically back into the working position. There is no
need to stop the tractor.
Along with the fully automatic „Nonstop“ overload safety, all component
carriers have a shear bolt as additional protection. See chapter
"OVERLOAD SAFETY“
for a description.
Setting range
•The overload safety release force can be adapted to the various soil types.
Normal setting
- Pressure in the hydraulic cylinders (40) must be approx. 10 bar greater than the nitrogen pressure in the gas accumulator (43).
--------------------------------------------------------------------------------------------------------------------------------------------

(Factory set) of the hydraulic cylinder (40)
--------------------------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------------------------
Should practice show that the overload safety reacts too often,
the pressure in the hydraulic cylinders can be increased with
the accompanying top-up device (42).
Increasing the pressure in the hydraulic cylinders:
- Shut-off valve in position A.
- Remove sealing cap (41) from shut-off valve and screw on
top-up line.
- Depressurize servo-valve on the tractor.
- Connect plug-in coupling (42) to the tractor.
- Open shut-off valve (position E). The hydraulic pressure
drops.
- Actuate servo-valve on tractor until the manometer shows the
desired pressure. Then
close the shut-off valve
(position A).
Take note!
The shut-off valve must
always be closed
(position A) when
ploughing.
- Depressurize top-up line using servo-
valve.
- Remove top-up line and screw sealing cap (41) back on.

Gas accumulator (43):
Pressure in the gas accumulator can also be altered.
A reduction or increase of gas pressure in the accumulator depends upon the
various soil types.
•With very light soil the gas pressure can be somewhat reduced.
Important!
No welding, soldering or mechanical work of any kind may be carried out
on the accumulator.
Altering pressure in the gas accumulator
This work must be carried out only by our Customer Service or by a specialist work
shop.
A special filling and testing device is required to reduce or increase the preload
pressure in the gas accumulator.
1. Reduce pressure:
a) Remove plastic cap.
Remove the lead mould plug (if it exists) in the gas filling plug (44) with a pointed tool.
b) Slightly loosen the gas filling plug (44).
c) Screw on filling and testing device.
d) Slightly open the outlet valve on the filling device.
Slowly let the nitrogen out (N) until the mamometer shows the desired pressure has
been reached.
e) Close outlet valve, remove filling device, tighten gas filling plug and knock the lead
mould plug (if it exists) back in.
2. Increase pressure:
Only use nitrogen (N) to fill the accumulator, do not use oxygen (danger of explosion).
f) Connect filling device to nitrogen bottle.
g) Remove plastic cap.
Remove the lead mould plug (if it exists) in the gas filling plug (44) with a pointed tool.
Slightly loosen the gas filling plug (44).
Screw on filling and testing device.
h) Screw testing device onto nitrogen bottle.
i) Slightly open the outlet valve on the filling device and fill with nitrogen until the mamometer shows the required pressure has been
reached.
k) Close outlet valve, remove filling device, tighten gas filling plug and knock the lead mould plug (if it exists) back in.
Take 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 that the accumulator pressure be checked and, if necessary, regulated after 4-5 years.
