4 PREPARATION OF TRACTOR
4.1 Tyres
Ensure that all tyres- especially the rear ones - are at identical pressure.
4.2 Lift rods
Adjust lift rods to equal length. Where there are alternative positions for the lift
rods on the lower links, use the rearmost position, in order to unload the tractor
hydraulics.
4.3 Check chains or sway blocks
It is essential that the check chains or sway
blocks are adjusted so that the lower links
are free to move sideways when in working
position.
4.4 Tractor hydraulics
During work the tractor hydraulics must be
set to "floating position" or to "mixed
control".
4.5 Front weights
Fit sufficient front weights in accordance
with the recommendations of tractor
manufacturer.
4.6 Terradisc 9/400 S
The TERRADISC 9/400 S is wider than 3 m. It is not allowed to transport it on
public roads if fitted to the tractor.
4.7 Front mounted operation
When the Terradisc 9 is used for front mounted operation, the steerability is
influenced and the distance between the front edge of the combination to the
eyes of the driver is increased. The road traffic rules should be adhered to!

5 ATTACHING AND DETACHING THE IMPLEMENT
5.1 Attaching to the tractor
−Set tractor hydraulics to "Position
control".
−Attach tractor lower links to the drawbar
(1) and secure.
−Fit top link so that it raises towards the
implement when in working position.
Secure top link (3) by means of spring
clip (4).
−Make electric supply connections for
lighting equipment, if public roads are
used.
5.2 Detaching from the tractor
−Park the implement always on firm and
level ground; re-attachment will then be
easier.
−Set tractor hydraulics to "Position
control".
−Lower the implement and disconnect
top link.
−Remove lower links from the drawbar (1).
−Detach electric supply-couplings if provided.
•Read and adhere to the General Safety Instructions as well as to
the Instructions ’Mounted implements’! See section 1!

10
6 THREE-POINT-LINKAGE
6.1 General Instructions
The mounting categories of the tractor and the implement must be compatible or
must be made compatible.
6.2 Vertical Adjustment of Drawbar
The drawbar (1) is vertically adjustable. In
case the implement can not be lifted
sufficiently from the ground or too much
tractor wheel slip will be experienced, the
drawbar must be fitted in the lower
position. In case the penetration is
insufficient, the pressure load on the roller
or rollers is insufficient or the tractor lift
capacity is insufficient, the drawbar must
be fitted in the upper position.
6.3 Change of the Drawbar Position
If required, change the drawbar position as follows:
Loosen bolts (S) of carriers (P), reverse carriers by 180 °, fit bolts (S) and secure.
Use Loctite and tighten nuts to a torque of 580 Nm.
•Read and adhere to the General Safety Instructions! See section 1!

11
7 ADJUSTMENTS
7.1 Share position
The share position of TERRADISC and TERRADISC Ü can be altered. A flat
share position ensures an even seedbed depth (point (5) and wings (6) work
nearly at the same depth) and reduces the traction requirement; a steep share
position ensures a good penetration, even in hard and dry soils.
With the TERRADISC having a shearbolt device and with the TERRADISC 9 Ü
having a bolted tine carrier (DS) with double cutting shearbolt device, the tine
position and thus the share position will be altered by repositioning the shearbolt
(7).
Hole A = flat position (especially for heavy sticky soils = easier to pull)
Hole B = steep position (especially for dry and hard conditions = improved
penetration)
With the TERRADISC Ü with cranked tine carrier (VZ), however, the share
position will be altered by slackening and by turning (180°) the eccentric bolt (8)
having first slackened shearbolt (7). Two tine positions are possible.
•Read and adhere to the General Safety Instructions! See section 1!
•Change the share angle position only with the implement lifted 2 - 3
cm only.
•Use only suitable spanners and tools.

12
7.2 Depth adjustment of the tines
The tines (19) respectively shares (5, 6)
should be set at a working depth of 8 - 12
cm; with greater soil unevenness or deep
wheel marks a deeper cultivation depth
may be required.
Adjust working depth of the tines after
raising the implement some cm as follows:
Placing the lower pin (2) in a deeper hole
=> increased working depth.
Placing the lower pin (2) in an upper hole
=> reduced working depth.
The upper pins (12) located above the
carrier (13) are for obtaining enough
clearance between the ground and the tube-bar-roller, with the cultivator raised.
If with raised cultivator the tube-bar-roller (14) is still touching the ground or is too
close to the ground, then with fully lowered cultivator the pins (12) must be placed
in a lower hole above the carrier (13).
The length of the top link should be adjusted so that the frame (15) is nearly
parallel to the ground. Top link fitting depends on the required re-consolidation
effect of the tube-bar-roller.
•Read and adhere to the General Safety Instructions! See section 1!
•When adjusting the working depth, raise cultivator a few cm, only!

13
7.3 Wing shares
The wing shares (6) must be fitted
underneath the frog (SF) as shown in the
right handed picture. The chamfered side of
the wing share must point upwards. An
incorrect mounting leads to share breakage.
7.4 Depth adjustment of the discs
The disc units (20) should be set at
approximate half the working depth of the
tines (19). The discs (18) are for mixing and
for levelling the ridges and grooves left by
the rear tines. When working too deep, new
ridges and grooves will be built, and when
working too shallow, the grooves and ridges
left by the tines will be levelled insufficiently.
An optimum depth adjustment is achieved
when the following tube-bar-roller (14) is
"filled" with soil throughout the total working
width.
If the roller area behind the discs is filled with
more soil than in the area between the discs,
the discs are working too shallow.
Conversely the discs are working too deep if
the roller area between the discs is filled with
more soil than the area behind the discs.
The working depth can be adjusted as
follows:
−Take out securing clip and remove pin (21).
−Adjust discs (18) vertically.
−Re-fit pin (21) and secure.
After depth adjustment of the discs, an adjustment correction is not
required after altering the depth of the tines!
•Read and adhere to the General Safety Instructions! See section 1!
•Adjust discs only with fully lowered machine.

14
7.5 Rollers
The Terradisc can be equipped with D400 and D540 tube bar rollers, with double
rollers as well as with packer rollers ZPW 500. The re-consolidation effect of the
roller (14) can be influenced by setting the top link steeper or more horizontal; in
doing so the tractor hydraulics must be set to "Floating position" or “Mixed control”
(with too much slippage).
Following results can be achieved:
Steeply set top link => small re-consolidating effect,
less steeply set top link => medium re-consolidating effect,
approximately horizontal set top link => good re-consolidating effect.
If the roller is sinking too deep into the soil (in light and sandy soils) and/or will not
roll and the top link cannot be set still more steeply (i.e. higher at the implement or
lower at the tractor), then the pressure of the roller can be reduced by setting the
tractor hydraulics to "Draft control" or "Mixed control". This is also recommendable
if the tractor shows too much slippage.
For such soils also a roller of 540 mm diameter instead of the standard one of 400
mm diameter is recommended.
In extremely sticky soils the packer roller ZPW 500 equipped with scrapers is
recommended. This roller ensures an exact depth guiding and a good re-
consolidation.
•Read and adhere to the General Safety Instructions! See section 1!
•Change top link position with fully lowered cultivator, only!

15
7.6 Packer roller scrapers
The scrapers (Z1) must be adjusted regularly. They should be positioned to the
surface of the roller by the adjuster nuts (Z2) of the scraper carrier (Z3) as shown
in the sketch above.
If soils sticks to the roller the scrapers must be adjusted. Dried soil on the roller
creates high wear and also damages the scrapers (Z1). Therefore always remove
soil before continuing work.
The scrapers must be adjusted as follows:
−The synthetic scrapers (K) must contact the roller with a little pressure.
−The scrapers (A) must be adjusted as close as possible to the roller, but must
not touch it.
−The standard scrapers (S) must always be in contact with the roller.

16
8 SHEARBOLTS
Each tine (19) and disc carrier is fitted with a shearbolt (7) which will save the
frame, tines and discs against overload.
Replace sheared bolt as follows:
a) Raise cultivator a few cm.
b) Remove all remains of the shearbolt (7).
c) Swing tine and/or disc carrier back into position.
d) Fit new shearbolt into hole concerned and tighten carefully.
Only shearbolts according to the schedule below should be used. Otherwise there
is a serious risk of damage to frame, tine or disc carrier or a premature failure
may be experienced.

9 TERRADISC 9 Ü WITH AUTOMATIC OVERLOAD SAFETY DEVICE
The TERRADISC 9 Ü cultivator is
especially designed for stony soils, and
the tines (19) are equipped with an
automatic overload safety device with
springs (35), protecting the implement
from damage when an obstacle is
encountered.
The tines trip back upon impact and
automatically return to the working
position once the obstacle has been
passed.
The cultivator is additionally protected by
means of shearbolts (7).
As special equipment also hollow discs
(25) with automatic overload safety
device are available.
•Read and adhere to the
General Safety Instruc-
tions! See section 1!
•Coil springs are under
load!
•If a tripped tine will not swing back into its working position, the bolts may be
tightened too much. Slacken the bolts concerned but note that the tine will
swing back into its working position with its full power. Keep a distance from the
swinging and tripping area of the tines!

18
10 OPTIONS
10.1 Outer discs
The outer discs (25) will be bolted to
the frame of the discs.
They should not work so deep as the
inner discs; their purpose is only to
move the soil which has been thrown
beyond the working width, into the
grooves left by the outer tines.
Working depth adjustment can be
made by means of pins (21). Secure
pin (21) after each adjustment.
For transport on public roads the
outer discs (25) must be folded
inwards.
To do so, remove pin (27), fold outer
disc (25) inwards and fit pin (27) in hole
(26) and secure.
•Read and adhere to the General Safety Instructions!
•Do not drive on public roads with outer discs being in working
position (folded out)!
