2. Desc r i p t io n of the m a c h i n e :
The rotary power harrow must be used for mechanical soil tillage and seed-bed preparation on
farms and in vineyards and orchards, as well as for row crops and specialty crops.
Moisture remains in the soil and the water balance of the soil is maintained since the soil is not
turned up as it is tilled. The vertically rotating cutters also prevent compaction of the soil, thus
resulting in optimum preparation of the seed-beds.
The power harrow is mounted on the tractor by means of a three-point suspension. It has five tine
units; the tine pick-up is rigidly mounted. The gear mechanism is driven via a PTO shaft and drives
the cutters in the housing via gear wheels.
The working depth is set by means of a hand spindle in combination with the support roller. The
friction clutch mounted on the PTO shaft protects both the harrow and the tractor from damage if
overloaded. An additional machine, such as a seeder, can be connected to the rotary harrow via a
further three-point suspension on the basic unit and a p.t.o. shaft on the main gear unit. In this way,
the seed-bed can be prepared and the seed sown in a single pass.
The working depth should be adjusted in line with the prevailing ground conditions in order to
obtain the best possible results. Large objects should be removed from the ground beforehand so
that the soil can be tilled correctly and to prevent premature wear on the tines.
The housing accommodates the various components making up the rotary power harrow. The
support roller, three-point frame, angular gear and tine units are bolted onto the housing.
The
three-point frame is made of robust sheet metal and bolted onto the housing. The bolts of the
lowe
r links support can be undone and the three-point frame displaced sideways on the rectangular
profile of the housing for off-center operation.
The
angular gear which is mounted on the housing diverts the tractor’s rotary motion through 90°
and drives the tine units via gear wheels.
Each tine unit comprises a tine flange, guard plate, two tines, bearing housing, bearing and
connecting elements. The tines are mounted underneath the guard plate and serve to loosen the soil.
They are secured by means of special bushings, washers, bolts and lock nuts.

3. Start-up and operation of
the
m a c h i n e :
*Befo r e using the machine
for the first t i m e
- Read through the
operating instructions for
the rotary power harrow
and additional attachments
and ensure that you are fully
familiar with the mode of
operation of all units.
- Check that the length of
the PTO shaft fits your
tractor. The PTO shaft
should include an
appropriate protective
mechanism!
* Attachment to the t r a c t o r
- Examine tools (tines)
and tine carriers for
signs of wear and
ensure they are
secured correctly.
- Check that the support roller
and three-point frame are
correctly secured to the housing.
- Now connect the
power harrow to the
tractor by means of
the three-point
suspension. Secure the
bolts of the upper and
lower links with
spring pins. Park the
tractor on level
ground and adjust the
upper link so that the
rotary power harrow is
horizontal.
- Now adjust the length of the
PTO shaft to match your
tractor. For this purpose,
hold
the two halves of the
PTO shaft side-by-
side in the shortest
lift-out position and
mark it accordingly.
Shorten the inner and
outer protective tube
by equal amounts.
Then shorten the
inner and outer
sliding profile by the
same amount as the
protective tube.
Finally round off the
cut edges and
carefully remove all
chips. Grease the
sliding profiles.
- Before engaging the
PTO shaft, carefully
clean and grease the
p.t.o. shaft of the
tractor and power
harrow. Then slide
the PTO shaft over
the p.t.o. shaft until
the locking pin
engages completely.
The friction clutch
of the PTO shaft
must be mounted at
the machine end.
-The
wo r k i n g depth
is now adjusted with
the aid of the hand
spindle in
accordance with
ground condition on
a firm and level
substrate or by
lifting the unit
completely.
The power harrow with
fitted tools and attachments
is now ready for use.

* Working with the power ha rr ow
- The tractor p.t.o. shaft must not be switched on until it is certain that the shaft will rotate
at not more than 540 rpm at maximum engine speed.
- The p.t.o. drive must not be engaged when the tractor drives running at full load.
-The
p owe r harrow may only be started and stopped from the t r a c t o r
driver’s se a t .
- The power harrow may only be switched on when there is no-one within its range of
operation and hazard area (radius of 10 m from the rotary harrow) due to the risk of
objects,
such as stones, being hurled away from the machine. The duly prepared machine
must be lowered to the working position before it is switched on. The rotary power
harrow can then be switched on.
- The machine must be lowered slowly in order to avoid damage to the tools and
attachments.
- During the work, the machine must be lowered to the working depth and left with the set
control hydraulics. The horizontal position of the rotary power harrow can be
corrected by
means of the upper link.
- The areas to be tilled should be inspected for visible large obstacles before staring so that
they can be removed from the harrow’s range and thus prevent damage to the tines and
drive elements.
- If a reversing manoeuvre is required at the end of the row being tilled, the tractor p.t.o.
must be switched off and the rotary harrow allowed to come to a complete standstill
before it is lifted out of the ground for the manoeuvre (risk of clods of earth being hurled
off by the tines).
- If the frame has been fully fitted with tools, its stability will be assured even without
support wheels.
- Dust clouds may form when operating the power harrow at higher speeds on dry ground.
Light respiratory protection should therefore be worn when using a tractor without
closed driver’s cab.

4. Maintenance, care and t r an s p o r t:
The PTO shaft must always be disengaged and the ignition key r e m ove db efo r es t a r t i n g
any maintenance and repair work on the power ha rr ow!
Maintenance or repair work must never be performed underneath the rotary power harrow
without appropriate supports. Precautions must always be taken to prevent the machine from
dropping inadvertently, for instance by using hoisting gear.
The rotary power harrow should always be placed on firm, level ground.
The power harrow type LXG is designed and built to require as little maintenance and care as
possible.
H oweve r , the following points should be o b se r ve dn eve r t h eless :
- All nuts, bolts and screws must be examined after the first five hours of operation and
then always before using the machine in order to ensure that they are secure. They
must
be retightened if necessary.
- The PTO shaft must be lubricated with sufficient sulphur-free grease every eight hours
of operation so that it can always be extended and retracted without difficulty. The
bearing points on the cutter unit, the spindle for setting the working depth and the
roller mount must be lubricated every 30 hours of operation via the corresponding
grease nipples.
- The oil must be checked every 20 hours of operation.
- Gear oil must be changed after approx. 200 hours of operation. A container must be
placed under the machine to collect the escaping oil and prevent contamination of the
ground. Waste oil must be disposed of in accordance with the regulations.
- The rotary power harrow should be stored in a dry place, on firm, level ground. It
should be secured with chocks or similar objects to prevent inadvertent tilting.
- The machine must be thoroughly cleaned before prolonged storage. Those parts which
are in contact with the ground during operation should be sprayed with corrosion
inhibitor.
- Particular attention must be paid to the condition of the tines in order to ensure
maximum occupational safety and high-quality results. Before starting work, the tine
must therefore be examined to ensure they are correctly secured and wear down
evenly. Bent tines must be replaced immediately.
- Vibrations in the rotary power harrow are usually due to imbalances in the tine unit
and may damage the machine. Switch off the rotary power harrow and the tractor if
the vibrations increase significantly during operation or if the machine’s running noise
changes suddenly. The cause must be located and remedied before resuming work.
6

- When cleaning the machine with a high-pressure cleaner, care must be taken not to
direct the high-pressure jet against bearings and seals, as this can result in
malfunctions and premature failure of the machine.
- The screw connections between tines and tine flange / guard plate must be checked
regularly. Always fit new lock nuts and new washers whenever the screw connections
have been removed. The condition and degree of wear on the tines and tine pick-up
must be checked regularly.
- When transporting the machine, care must be taken to ensure that there is no one and
nothing in the immediate vicinity when sluing outwards with the tractor.
- The power harrow should only be repaired by a specialist repair shop or a authorized
customer service center.
Changing and
regrinding t i n es :
Tines should only be reground and changed by your dealer, since co n si d e r ab le hazards c an
arise if they are fitted i n co rr ec t ly.
Removal of the t i n es :
- First switch off the tractor and remove the ignition key.
- Disengage the PTO shaft and then the rotary power harrow from the tractor.
Remember to support it so that it cannot tip ove r i nad ve r t e n t ly.
- Turn the power harrow over with the aid of hoisting gear so that the tines can be
reached without difficulty.
- Remove the fastening bolt and nut with a suitable wrench.
• Im
p
ortant: For safet
y
reasons, new self-lockin
g
nuts and new washers must alwa
y
sbe
used whenever the tints are changed.
Ensure that the tines are fitted co rr ec t ly in the direction of r o t a t io n .
Installation of the t i n es :
- Fit the tines in the correct order.
- Fit the fastening bolt, washers and nut.
- Tighten the self-locking nut twice.
R eg r i nd i n g the t i n es :
If the tines have to be reground, care must be taken to ensure that each pair of tines in the
tine unit is reground. This prevents the tine unit concerned becoming imbalanced.
Use the transport aids or three-point hitch provided on the housing to transport and
handle the p owe r ha rr ow.

5. Safety i n s t r u c t io n s :
- The Implements may only be used when all safety mechanisms are in place and
fully functional.
- All faults capable of impairing safety must immediately be remedied by specialist
personnel.
- The operating instructions of any additional attachments installed must be read
through carefully and observed.
- Never climb onto the tractor or leave it unattended when the p.t.o. shaft is running.
- Never allow anyone who is not familiar with the safety and operating instructions to
use the machine.
- Remove all visible large objects which may be picked up and hurled aside by the
rotary power harrow. Particular attention must be paid to loose wires on the ground.
- Adjust your driving speed in line with the ground conditions and prevailing
circumstances.
- No one may remain within 10 meters of the power harrow during operation of the
machine. High
risk of injury due to moving machine parts and objects being hurled
away from the machine, such as stones, etc.
- Never climb or reach in between the power harrow and the tractor with your arms or
legs during operation of the machine – high
risk of injury! (This is only permitted
when the machine has been lowered to the ground and the tractor switched off.)
- The machine should only be operated in full daylight . Traffic regulations must be
observed when driving on public roads. Adequate illumination must be ensured when
driving in twilight or darkness (A detachable set of lights is recommended.)
- Never climb or reach in between the support roller and cutter unit with your arms or
legs – high
risk of i n j u r y.
- Always wear tightly fitting clothes so that these cannot be caught between rotating
parts of the machine.
- Safety stickers must be kept clean and observed!
- Never open or remove the guard elements during operation. Worn or defective parts
must immediately be replaced by new parts.
8

- The cutter unit must never be operated when the power harrow is lifted off the ground.
- Driving a tractor on steep slopes can be dangerous. If work on steep slopes is
unavoidable, great care should be exercised. Do not take bends too tightly.
- No one may ever ride on the machine either during operations or while it is being
transported, not even over short distances.
- Always examine the rotary power harrow for signs of damage following a collision
with any objects. Such damage must always be repaired before resuming work.
- Maintenance and repair work may only be carried out when the PTO shaft and
machine have been disengaged form the tractor.
- Never crawl under a rotary power harrow which is still connected to the tractor, as the
machine may be lowered at any time – high
risk of i n j u r y.
- The accident prevention regulations of the employers’ liability insurance association
must be observed when using the machine.
- When traveling round bends, take account of the larger width / length (turning circle)
and considerable weight of the rotary power harrow.
- Ensure that the PTO shaft halves and protective tubes overlap as prescribed, both in
the transport position and in the working position. Read the operating instructions for
the PTO shaft in this context.
- The PTO shaft should only be engaged and disengaged when the tractor engine is
switched off and the ignition key has been removed.
