TRACTOR REQUIREMENTS
Tractor
To operate this machine the following tractor requirements
are necessary:
Tractor power: at least 92 KW / 125 HP (5 plough
body)
at most 265 KW / 360 HP (9 plough
body)
Hitching category: Lower link Cat. III
Connections: See table "Necessary hydraulics
and power connections"
Tyres
Wheels
- The air pressure in the rear tyres of the tractor when
ploughing depends on the type, you can take as reference
value 0.8 bar.
- Under heavy working conditions additional wheel weights
can be advantageous.
See the operating instructions of the tractor manufacturer.
Distance between the wheels
The distance between the wheels (A1) should be of 1.2
m - 1.5 m.
A1 = 1.2 ... 1.5 m
A2 = max. 3 m
External dimensions
The external dimensions (A2) of the rear wheels may
not exceed 3 m. When the 3 m are exceeded, the
manoeuvrability is relatively limited.
Ballast weights
Ballast weights
The front of the tractor is to have sufficient ballast to
guarantee braking and steering capabilities.
At least 20% of the tractor’s tare weight
on the front axle!
Lifting gear (three-point linkage)
- The tractor’s lifting unit (three-point linkage) must be
designed for the load that occurs. (See technical data)
- The lifting struts are to be set to the same length with
the corresponding adjustment device.
(See the tractor manufacturer’s operating manual)
- Select the rear position if the lifting rods can be adjusted
in various positions on the lower link. This relieves the
pressure on the tractor’s hydraulic system.
- The limit chains resp.stabilisers of the lower links are to
be set so as no side movement of the hitched devices
be possible. (Safety measure for transportation)
- The upper link is to be removed according to the data
provided by the tractor manufacturer.

Hydraulic control on the lifting gear
The lifting hydraulics shall be switched on

Safety advice
Safety information
Read and observe the operating
instructions, and in particular the safety
information, prior to putting into service.
Warning!
Risk of crushing.
When operating the power lift ,stay
outside the lifting area of the three-point
suspension.
Safety information
See Attachment C - statutory information
on hitched implements drawn by towing
vehicles in road traffic.
First putting into operation - Fill turning
cylinders
Beware!
Danger of injury due to uncontrolled
tipping! For transport, empty the oil from
one turning cylinder. Fill the respective
cylinder accordingly before the first
putting into operation.
1. "Open" the stop cock on the empty cylinder and "close"
on the retracted cylinder
2. Connect the hydraulic lines of the turning unit to the
tractor and fill with oil the emptied cylinder
3. "Open" the stop cock on the retracted cylinder
4. Turn the plough in transport position
1100 mm
Couple the three-point device onto the
tractor
Safety information
Secure all connecting bolts on the three-
point with lynch pins (1)!
Observe and apply the tractor manual on
the locking settings on the tractor side!
1. Switch the tractor hydraulic to position control
2. Take out the lower link
- Mount the plough on the lower links and secure it in the
lower links with arrester hooks.
- Stabilise the lower link laterally
3. Position upper link (1)
- Take out the upper link (1) so that the connection point
(P1) on the plough is a little higher during operation than
the connection point (P2) on the tractor.

Set furrow width "First body"
Plough starting position:
Optional pin: Changing setting prior to use
Optional hydraulic cylinder: Setting can also be changed
during use.
Mode of operation:
The plough position relative to the tractor is adapted with
the setting furrow width "First body". The plough is moved
with a pin or a hydraulic cylinder depending on the version.
The setting is to be selected so that the furrow width of
the first body (S1) is the same as the other plough bodies.
Design
with pin:
The furrow width "First body" (S1) is adjusted steplessly
by turning the pin (Sp).
- Furrow width (S1) too narrow -> turn pin (Sp) shorter
- Furrow width (S1) too wide -> turn pin (Sp) longer

during ploughing.
Setting furrow width
Plough starting position:
Variant Standard:
Change setting before use
Variant Servo Plus:
The setting can be changed also during operation. (See
Chapter "Servo Plus" for details)
Mode of operation:
The plough working width is determined by the furrow
widths set for the individual bodies.
Variant Standard: 5 defined furrow widths can be set
mechanically.
Variant Servo Plus: The furrow width can be set steplessly
using the hydraulics.
Variant: Standard
Setting the furrow width per body:
- Loosen front hex head bolt (vS).
- Remove rear hex head bolt (hS).
- Swivel the fastening bracket until the required furrow
width is reached and the hex head bolt (hs) fits into one
of the holes (Bo).
- Re-tighten hex head bolts (vS, hS).

Setting the depth
Plough starting position:
The plough must be rotated in working position
Mode of operation:
The working depth is set on the chassis and via the lifting
height of the tractor lower link.
The adjustment of the chassis height is made with the help
of the hydraulic cylinder (Zy).
The setting of the working depth resp. is changed via the
number of the depth stops (AS) swivelled in.

Design:
- Lift the chassis
- Remove cover of the depth stops (lynch pin) and fold
up
- Swivel the depth stop in or out (less depth stops = more
working depth)
- Fold up and secure the cover of the depth stops
- Lower the chassis (until the cylinder (Zy) lies on the
depth stops.)
- Adjust the lifting height of the tractor lower link to the
required working depth.
One depth stop corresponds to a change
in the working depth of approx. 2 cm
Adjusting the plough tilt
Plough starting position:
Prior to use.
Mode of operation:
The tractor drives in the furrow and is thus at a slope. The
plough should sit as vertical (90°) as possible to the ground
during ploughing. The setting of the tilt is performed via
adjustment screws at the swivel unit.
Design:
- Adjust the tilt per side with the adjustment screws (1).
(Example: If the plough is swivelled to the right, the left
stop can be set)
- Check that the new setting allows the plough bodies
to stand approximately vertical (90°) to the ground per
side.

074-09-60
When ploughing on slopes, it is
recommended that the tilt is set somewhat
more than 90°.
When ploughing on hard ground, it is
recommended that the tilt is set somewhat
less than 90°.

tip is adjusted in the range "S" lower or higher by turning
the cam bushing.
Design:
- Loosen bolts and turn cam bushing
- Retighten bolts after adjustment
The following applies to the basic setting:
The gap (A) between plough and share cutting edge must
be the same for all ploughing components.
- Check the gap (B1) at the last plough component
Type W*): B1 = 0 - 5 mm
Type UW, UWS, WSS*): B1 = 10 - 20 mm
- Set the same measurement for gap (B) as for B1.

Mode of operation
The furrow width can be adjusted steplessly using a
hydraulic cylinder (2). The furrow width of the first plough
unit is automatically adjusted at the other plough units. The
mechanical construction turns each plough unit at the point
of rotation (1) at the same time while adapting the chassis
to the new working width.
(1) Point of rotation
= maintenance point (see Section "Maintenance" for details)
(2) Hydraulic cylinder
(3) Display of furrow width
Forrow width can be adjusted during operation.
Ploughing around obstacles (masts, trees, ...) can be
performed without problem as can ploughing up to fences.

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.
The plough body swings back into work position
automatically.
Along with the fully automatic „Nonstop“ overload safety,
all component carriers have a shear bolt as additional
protection.
Setting range
The overload safety release force can be adapted to the
various soil types.
Normal setting
Nitrogen pressure in the gas accumulator (43) (Factory
set) 80 bar
Pressure adjustment area of the hydrauliccylinder (40) 90

Should practice show that the overload safety reacts
too often, the pressure(* in the hydraulic cylinders can be

Increasing the pressure in the hydraulic
cylinders
Increasing the pressure in the hydraulic
cylinders:
- Shut-off valve in position A.
- 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!
