It may NOT
seem inconvenient and unnecessary to read and
observe the operating instructions. It is not enough
to hear and see from others that an implement is
good, and then to buy it and believe that everything
takes care of itself. The person concerned would then
not only cause damage to himself, but also make the
mistake of assuming that the cause of any problems
is due to the implement, instead of himself. To ensure
success, one has to go into the spirit of things, and
instruct oneself about the purpose of all equipment
on the implement and gain experience with its
handling. Only then can one be satisfied both with the
implement and oneself. These operating instructions
aim to achieve this.

Quality for Professionals
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 or the safety 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 (additional equipment) is mounted on the
bracket for the harrow array (see point 17 Accessories).
When driving on roads after field operation, the harrow arrays should be cleaned of
harrowing residues (soil, grass, etc...).
5 Operating manual for the grassland harrow
5.1 Mounting on the tractor
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.
The lifting links must be adjusted to the same height on the left and on the right. The
implement must be mounted on the 3-point linkage of the tractor.
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.
5.2 Safe parking
To ensure safe parking of the
implement, fold both parking supports
down as shown in Fig.: 1. On the
GS 600 M1, you also have to fold down
the third parking support (rear). On the
GS 300, either position the levelling
plate further down or, if a pneumatic
seeder is mounted, you can also use the
third parking support.
With hydraulic folding, you must hook the safety chain onto the side wings and also
lock the 2/2-way ball valve, which is located on the folding cylinder. Then the pressure
in the hydraulic hoses to the tractor must be relieved.

5.3 Test folding of the grassland harrow (with hydraulic folding)
Couple the hydraulic line plugs (ensure that they are always kept clean). Fill the
cylinder with oil. The cylinder is filled as soon as the safety chains are relieved. Unhook
the safety chains and hook onto 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 hook on the safety chains or to close the stop tap.
6 Working position and setting the working depth
The height-adjustable levelling plate removes coarse unevenness in the grassland and
spares the tines unnecessary strain.
Due to the narrow line distances of these individual tines (75 mm for 10/12 mm tines
and 50 mm for 8 mm tines), the sward is optimally prepared and the plants can
germinate rapidly after reseeding.
The two front tine rows tear up the sward. The rear tine rows produce an optimal
seedbed for the new grasses.
If the rear tines should work more
aggressively, you can choose one of four
levels. At an optimal forward speed, the
tines make an elliptical motion. The
steeper the position of the tines, the
smaller the motion. The flatter the position
of the tines, the larger the motion. If the
sward is dense and intense tillage is
required, the tines should be positioned
more steeply (see Fig.: 2).
The front and rear tine rows should
penetrate the soil to the same depth
(working depth).
If the 10/12 mm tines should work more intensively, position the feeler wheels higher
up.
If the 8 mm tines should work more intensively, extend the top link.
The tine aggressiveness is set using an adjustment lever. One adjustment lever per
row and array (Fig.: 2). Depending on the soil type, more load can be applied to the
tines through the array and the frame.
Fig.: 2

Quality for Professionals
To scatter molehills effectively, front
scraping plates are offered (for an
additional charge). The mounting position
of these front scraping plates is shown in
Fig.: 3. Stop bars are inserted in the joints
of the side wings (see Fig.: 4). On hilly
terrain, these can be removed to achieve
better ground adaptation. The stop bars
can be stowed in the accessories roll.
Repositioning of the stop bars is only
possible in transport position.
CAUTION: Driving in
curves is not permitted. If
it should be necessary
after all, these curves
must be driven in a very
large radius.
6.1 Levelling plate (optional)
The levelling plate (optional) eliminates molehills after the
winter and serve to roughly level the grassland. The height
should be adjusted so that it runs along the sward just
above the ground. It should not scratch into the sod.
To adjust the levelling plate, the pins must first be
removed. If you have the GS 600 M1, then you can adjust
the two outer wings by hand. To be able to adjust the larger
centre array, it is better to remove the pins and to adjust
the height of the levelling plate with the tractor hydraulic
system. When the desired working height is reached, the
plate is fastened again with the pin and linch pin.
The design of the levelling plate on the GS 300 M1 is the
same as the centre array of the GS 600 M1.

Quality for Professionals
To optimise the guidance of the levelling plates/harrow arrays, the feeler wheels also
have to be adjusted. This is achieved as follows:
•Use the supplied adjustment handle.
•Put the handle into position as shown in Fig.: 5 and clamp or fix it with the pin.
•Remove the pin that holds the feeler wheel and use the hook to move it to the
desired position.
7 Adjustment spindle
To simplify the adjustment of the middle levelling plate, the
"Adjustment spindle accessories kit" can be purchased. To
do this, the spindle is turned up until the pins that secure the
levelling plate are relieved. Then the pins are removed and
the levelling plate can be moved to the desired depth. The
pins are inserted back into the adjustment grid and the
spindle is turned up/down until it is relieved again.
8 Maintenance and care
When the implement is lifted off of the ground, the two side wings of the frame should
be pointing slightly down. If this is not the case or if the wings are pointing down too
much, the stop bolts on the joint must be adjusted.
To maintain the implement in good condition even after a long service life, the following
instructions must be observed:
In the supplement "For your safety…" you will find some basic safety regulations
for maintenance work.
Original parts and accessories are designed especially for the machines or
implements.
Please note that 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 constructional properties of your implement. The manufacturer rules
out any liability for damages resulting from the use of non-original parts and
accessories.
The manufacturer is not liable for any unauthorised modifications and the use of
components and auxiliary parts.
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.
Fig.:

10
Quality for Professionals
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.
During the winter, the implement should be protected against rust with an
environmentally-friendly product.
Park the implement protected from weather conditions.
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).
9 Location of the rating plate
The rating plate is found on the main frame beside the mounting frame bracket.

12 Changing the tines
To replace broken or worn tines, all you have to do is loosen the nut and take out the
tine (for 8 mm and 10/12 mm tines).
•As shown in the image on the left (Fig.: 9), you must hook on the new 10/12 mm
tines and re-tighten the nuts.
•As shown in the image on the right (Fig.: 10), the 8 mm tines must be fastened
with the bolt. Ensure that the bolt rests firmly on the tine and that all tines form a
straight line. The large flat washer should rest on the tine.
Unscrew the nut
13 Tine safety
As a standard, the GS series is equipped with a
tine safety that prevents loss of the 10/12 mm
tines by means of a rope. It protects the tines so
that they do not get lost on the pasture or on the
field. This also prevents damage to other
implements, e.g. the mower or the baler.

16 Cropping tips for using the GS 300 M1/ GS 600 M1
Seedbed preparation is always required before reseeding. With the grassland harrow
GS 300 M1 / GS 600 M1, this procedure is optimally accomplished with 4 tine rows.
With its thorough and effective mode of action, the GS 300 M1 / GS 600 M1 can be
optimally integrated in your overall management concept.
The goal of your concept will be to improve yields and to increase the valuable grasses.
Other effects of tilling your fields with the GS 300 M1 / GS 600 M1, such as
Soil aeration,
Regulation of the water balance,
Incorporation of the seed and
Promoting tillering
make a significant contribution to the formation of good crops.
The success of weed control without chemicals and high yields, however, depend very
strongly on you, as you will be required to closely observe the processes in your soil.
Reseeding of grassland is theoretically possible during the entire frost- and snow-free
period. Gaps in the crops should already be reseeded in the spring to prevent weed
competition. As a matter of principle, you should reseed more frequently and therefore
work less aggressively and reduce the seed quantity.
Reseeding can be performed in the spring as soon as the soil has warmed up a little.
The soil must have good trafficability, i.e. the seed should not be "smeared in" in any
case.
Reseeding in the spring has the advantage that the spring humidity and the disturbed
soil can be used as a seedbed. However, despite good germination, the grass can dry
out during a summer drought, and the pressure of the old sod is greater in the spring
due to the stronger growth spurt.
The optimal strength and depth setting, forward speed and the adjustment of the tines
and seeding rate must be set with your understanding of the correlations between the
soil properties and weather conditions, which can vary greatly in different regions.
