5 Safety instructions
This chapter contains general rules of conduct for the intended use of the implement and safety-
related information that should always be observed for your safety.
The list is very extensive, and some of the information does not apply exclusively to the delivered
implement. However, the summary of the information often reminds you of unconsciously neglected
safety regulations for the everyday operation of machines and implements.
The general accident prevention regulations of the respective countries must be observed. Always
secure the parked implement against unintentional rolling. The implement may only be used by persons
who are informed of the hazards and who know the regulations for transport on public roads.
5.1 Intended use
The implement is designed solely for normal use in agricultural operations (intended use).
Any other use is considered to be non-intended. The manufacturer is not liable for any resulting damage,
the operator alone bears the associated risk.
Intended use also includes compliance with the conditions for operation, maintenance, and repairs
prescribed by the manufacturer.
The implement may only be used, maintained and repaired by persons who have relevant experience
and were instructed on the risks. The safety instructions must also be handed over to other users.
The applicable accident prevention regulations as well as the other generally safety-related,
occupational health and road traffic regulations must also be observed.
The manufacturer is not liable for any damage resulting from unauthorised modifications and the use of
components and auxiliary parts.
The implement is intended for operation at temperatures between +5°C and +40°C.

8 Road transport
8.1 General
The axle load and the total weight of the towing vehicle may not be exceeded. The mounted implement
must be identified with warning signs or stickers with red and white slanted lines (according to DIN,
ÖNORM or respective STANDARDS) according to the regulations of the specific country.
Any part posing a traffic hazard or dangerous parts must be covered and additionally identified with
warning signs or stickers. Warning signs or stickers should be visible at a height of max. 150 cm above
the road when driving. Lighting equipment of the towing vehicle may not be hidden by the implement,
otherwise they must be replicated on the mounted implement. The steering capacity of the tractor must
not be impeded or reduced by the mounted implement!
Semi-mounted implements may only be towed on public roads
with an operating permit.
Hydraulic implements must be folded in transport position.
Ensure that the stop tap is closed and the securing chains are
hooked.
Also ensure than none of the safety splints were lost during
operation.
Comply with the regulations of your country's legislation.
Only relieve the hydraulic hose at home by putting the tractor
control unit into float position. The holder for the warning signs
with lighting (additional equipment) is mounted on the bracket
for the jack (Figure 2).
When driving on roads after field operation, the implement
should be cleaned of field residues (soil, grass, etc...).
8.2 Calculation of the weight ratios
If you want to drive with an implement that is attached to the 3-point linkage, you must ensure that you
do not exceed the tractor's permissible axle loads and tyre load capacities with the mounted implement.
The front axle of the tractor must be loaded with at least 20 % of the net weight of the tractor.
All of these values can be determined with this calculation:

9 Layout and mode of operation
Thanks to its robust and compact design, the RH 600 Rotary Hoe is ideal for breaking up crusted soils
and designed for controlling weeds in various crops.
The rotating hoe rings bury or uproot the weeds, promote tillering of the crop, incorporate oxygen into
the soil and break up hard soil crusts. The slanted position of the rings increases the degree of efficacy
and makes the implement even more aggressive. The rotating rings prevents the implement from
clogging and makes it possible to comb out the weeds.
The Rotary Hoe is insensitive towards organic residues, which makes it highly suitable for mulch
seeding.
The work is performed by 6 mm-thick spring steel pins, which are cast in a slanted polyurethane disc.
These star rings with a diameter of 50 cm are separately suspended and can therefore individually adapt
to ground undulations. The ring not only adapts to the ground upwards, but also downwards. The
downward preload force is achieve through the ring's net weight. Thanks to the tool-free quick-release
fastener on each arm, it is possible to adjust the pitch from 0 – 30°in 5°-increments.
Because the working rings are arranged back-to-front from the middle, no lateral pulling forces arise. To
ensure full area tillage, the middle ring is slightly set back, otherwise the two rings in the middle would
interlock and this would cause damage to the crops.

9.1 Working position and setting the working depth and pitch
The aggressiveness of the star rings is adjusted using the feeler wheels
(Figure 5) as well as using the lifting unit and the top link.
The downforce is hydraulically infinitely variably adjusted from the tractor by
extending the hydraulic top link. This increases the pre-tensioning of the
compression springs and they put more pressure on the rings. Moreover, the
preload force on each arm can be individually adjusted. If the top link is retracted,
the pressure on the rings is reduced until they hover above the soil horizon.
The working speed strongly affects the aggressiveness. Higher speeds result in
more aggressive action of the implement.
9.1.1 Setting the preload force on each arm
The preload force is increased/reduced by releasing the
quick-release fastener and adjusting the spring preload
with the pattern of holes.
To be able to actuate the quick-release fastener to set the
preload force, the clamping mechanism must be
released. This is done by pressing on the spring-loaded
bolt, which clamps the quick-release fastener onto the
hollow profile.
The quick-release fastener is therefore released and can
also be turned down and out of the way if there is a lack
of space.
Thanks to the handle, the preload plate of the spring can
be adjusted up or down in the 2nd step. When the
preload plate is pulled out, the preload force on each ring
increases. When the preload plate is pushed in, the
preload force is reduced.
In the last step, the quick-release fastener must be pulled
to the front again and the clamping mechanism must be
released.
9.1.2 Adjusting the pitch
By pressing the quick-release fastener lever to the front (in the direction of travel), you unlock the ring
fastening. By turning the arm holder, you adjust the pitch of the ring. The angle is adjusted by 5 degrees
with each locking notch. The ring is fastened again by leaving out the lever.

9.2 Quick lifting device (installed as a standard)
Using the quick lifting (available as an
accessory), the implement can be
adapted to the crop without using tools,
only the folded-up arm must be fixed with
the pin in the top hole. If the quick lifting
device is not active, the pin can be stored
in the parking position in the last hole.
The downward swivelling range for the
arm can also be limited by inserting the
pin in the second hole from the bottom.
The ground clearance is 290 mm when
the arm is lifted. By folding up the arm, a
width of approx. 150 mm will not be
worked.

Page 17
Figure 12: Limitation of the negative range
Figure 11: Quick lifting device activated – lifted position
Figure 10: Pin in parking position
Figure 13: Installed plates to prevent misapplication
The installed plate (see Figure 13) serves to prevent misapplication. As a result, the quick lifting device
cannot be used for securing the work elements.
CAUTION!
Before folding the implement, the four arms left and right of the pivot point must be in
working position. Risk of collision with the arms when they are folded up!
CAUTION!
The quick lifting device may NOT be used for securing, so that the top link puts
additional pressure on the implement to be able to work more aggressively!

Page 18
10 Operation
10.1 Mounting on the tractor
The implement must be mounted on the 3-point linkage of the tractor.
The lifting links must be adjusted to the same height on the left and on the right.
Mount the top link so that it slants down towards the tractor during operation. (Observe the specifications
from the tractor manufacturer.)
Adjust the side rods so that the implement can swing freely on the field, but is fixed when the implement
is lifted.
Under difficult operating conditions, additional wheel weights can be useful. Please also refer to the
operating manual from the tractor manufacturer.
The tractor should be equipped with sufficient ballast weight at the front to ensure the steering and
braking capacity. At least 20% of the empty vehicle weight is required on the front axle.
10.2 Safe parking
To ensure safe parking of the implement, lower the
parking support and the two feeler wheels on the
middle frame, as shown in Figure 14.
10.3 Test folding
Connect the hydraulic lines with the towing vehicle, and ensure that the connections are clean to prevent
contamination of the oil.
Actuate the control unit to fill the cylinder with oil. The cylinder is filled as soon as the securing chains
are relieved. Dismount the securing chains and mount on the other end of the chain. Ensure that no one
is standing in the danger area and that you only fold the implement when it is lifted from the ground.
When folding into transport position, the implement must also be lifted from the ground. Do not forget to
mount the securing chains and to close the stop tap.
When uncoupling the implement, you must relieve the hydraulic hose through the float position before
you pull it out.
CAUTION!
Before folding the implement, the four arms left and right of the pivot point must be in
working position. Risk of collision with the arms when they are folded up!

instructions:
•All bolted connections should be re-tightened at the latest after 3 operating hours and again after 20
hours, and then checked regularly. (Loose bolts can cause significant consequential damage, which
is not covered by the warranty.)
•The grease points on the joints and bearings must be lubricated regularly (approx. every 10
operating hours with universal grease).
•For implements with fast coupler, the guide slots must also be lubricated.
•After the first 10 operating hours and subsequently every 50 operating hours, the hydraulic units and
tube lines must be checked for leaks and the bolted connections must be tightened if necessary.
•Check the hydraulic hoses for wear before every operation.
•Caution! Liquids escaping under high pressure can penetrate the skin. For this reason, a physician
must be consulted immediately in case of accident!
•After cleaning, lubricate all of the grease points and distribute the grease evenly in the bearing
points (e.g. perform a short test run).
•Do not use a high pressure cleaner to clean bearing and hydraulic parts. The paint can be damaged
by cleaning with excessive pressure.
•Park the implement protected from weather conditions.
•During the winter, the implement should be protected against rust with an environmentally-friendly
product.
•Hydraulically as well as mechanically folded implement must only be parked in a folded state.
•Put down the implement in a way that the tines are not needlessly strained.
•Occasionally check the tyre inflation pressure (tyres 16x6.50 approx. 2 bar, 18x8.50 approx. 3 bar).
•Original parts and accessories are designed especially for the machines or implements. Please note
that spare parts and accessories not supplied by us have also not been tested and approved by us.
The installation or use of such products can therefore possibly negatively change or impede the
