7 Operating manual for GK 400 M1
7.1 Mounting on the tractor
The air pressure in the rear tractor tyres should be 0.8 bar during operation. If the tyres have a
lower load capacity, increase the pressure.
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.
Mount the implement on the 3-point linkage of the tractor.
Mount the top link so that it slants down towards the tractor during operation. Also refer to the
sticker on the implement (observe the specification of the tractor manufacturer).

Page 12 Translation of the original operating manual
After coupling the lower link, turn around the parking support by pulling out the pin, reposition it
and then secure. (Fig. 2; Fig. 3)
Fig. 2
Fig. 3
Connect the hydraulic hoses to a double-acting control unit. During connection, make sure that
the hoses are unpressurised both on the tractor and implement sides.
PLEASE NOTE!
To ensure correct connection, the hydraulic hoses are
labelled as follows:
1 red cable tie: cylinder extends (A in
Fig. 4),
2 red cable ties: cylinder retracts (B in

Thanks to its robust and compact design, the Grassland Combi GK 400 M1 is ideal for new seeding,
reseeding, and controlling weeds on grassland.
The height-adjustable levelling plate removes coarse unevenness in the grassland and spares the
tines unnecessary strain.
Due to the tight line distances of the individual tines (72.5 mm for 10 mm or 12 mm tines), the sward
is optimally prepared and the plants can germinate rapidly after reseeding. With the high contact
pressure of the utilised roller, seed soil contact is improved and the nutrient supply to the reseeded
plants is optimised.
To obtain the best possible rolling results, a forward speed of 8 km/h should not be exceeded. A
speed of 6-12 km/h is ideal for grassland.
9 Working position and setting the working depth
9.1 Depth adjustment
To adjust the depth of the GK 400 M1, 2 work steps are required.
Depending on how aggressively you want to till the soil, slightly extend or retract the cylinder to
transfer the weight of the roller onto the harrow tines.
The lower link must be positioned such that the frame of the implement is horizontal to the field.
Reference points for this are the shaped tube (160 x 80 mm) or the pneumatic spreader (this
should be positioned vertically to the field).
During operation, the top link on the implement side must always be attached in the elongated slot.
For normal operation, the pin should be in the middle of the elongated slot.
If you want to use the GK 400 M1 with the roller lifted, i.e. the roller in the highest position and the
roller cylinder completely retracted, you must firmly attach the top link on the implement side. This
position must also be used in road traffic.

Page 14 Translation of the original operating manual
9.2 Aggressiveness adjustment
In addition to the depth, the aggressiveness of the tines relative to one another on the GK 400 M1
can also be changed. To do so, you only have to insert the pins for the harrow rows as desired in a
higher or lower hole. (Fig. 6)
Fig. 6
1: Aggressiveness adjustment
This makes it possible to adjust the 2 harrow rows with 12 (10) mm tines at different degrees of
aggressiveness. This also allows for compensation of various degrees of wear on the tines.
The two rows of tines tear open the sward and produce an optimal seedbed for the new grasses. If
the front row of tines should work more aggressively (e.g. under hard soil conditions), you must
place the pin in one of the top holes at the rear. In this way, the aggressiveness of two rows can
adjusted independently.
For this purpose, you can select one of seven 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. 6).
9.3 Levelling plate
The levelling plate 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. However, if the
sod is very uneven, allowing the levelling board to slightly
penetrate into the soil can improve the levelling effect on
the long term. To adjust the working height, remove the (4
pcs.) locking pins, crank the levelling plate to the desired
height, and fix it again with the 4 pins. (Fig. 7)
Fig. 7
TIP!
Remove the two pins on the right first, and then the two left pins, so that you can lift
the levelling plate more easily with the crank.

Tranlation of the original operating manual Page 15
The levelling plate has a shear-off safety to prevent
damage to the frame due to excessive loads on the
levelling plate.
The implement accessories include 3 sets of shear
bolts. When these have been used, attention must be
paid to the quality of the replacement bolts. Only
M12x60 bolts with a quality of 4.6 may be used.
The tightening torque of 10 Nm for the M12 bolts may
not be exceeded. If the M16 bolts behind have become
loose, a maximum tightening torque of 15 Nm must be
observed (Fig. 8).
Fig. 8
9.4 Use of individual tools
With GK 400 M1, it is also possible to use individual tools (levelling plate, harrow, roller) separately
or in any combination, e.g. you can use the roller alone by completely extending the roller cylinder.
In this way, you can also use the implement on field crops for rolling after seeding.
If you only want to level and roll, position the roller and the levelling plate all the way down so that
the harrow rows are lifted off the ground. In addition, fix the rows of tines in the first or lowest hole.
10 Maintenance and care
10.1 General maintenance instructions
To maintain the implement in good condition even after a long service life, the following instructions
must be observed:
Before every operation, check the hydraulic hose lines for wear, damage and ageing.
When replacing the hydraulic hose lines, lines must be used that comply with the technical
requirements of the implement manufacturer.
In Point 5, 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 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
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.
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.

Page 16 Translation of the original operating manual
Put down the implement in a way that the tines are not needlessly strained (roller all the way
down, use the parking supports at the front).
10.2 Regular maintenance 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).
Regular visual inspection of the tine safety must be performed.
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,
hydraulic hoses and couplings must be checked for leaks and the bolted connections must be
tightened if necessary.
Hydraulic hose lines must be replaced at the latest 6 years after their manufacturing date.
The manufacturing date of the hydraulic hose lines is specified on the fittings.
The platform kit and its access ladder must be visually inspected on a regular basis.
The rubber for fastening the access ladder of the platform kit must be checked regularly for wear
and replaced if necessary. It should only be replaced by trained specialist personnel and with
original parts.
10.3 Changing the tines
To replace broken or worn tines, all you have to do is loosen the nut and take out the tine (10 or
12 mm tines).
As shown in Fig. 9, you must hook on the new 10 or 12 mm tines and re-tighten the nuts.
Pay attention to the proper line distance! The tines in the rear row cut the distance of the front
tines in half.

Tranlation of the original operating manual Page 17
10.4 Tine safety
As a standard, the GK series is equipped with a tine safety
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.
Fig. 10
10.5 Repairs and service
In case of failure or damage to the Grassland Combi, please contact the manufacturer. The contact
data can be found in chapter 3.
11 Information on nature conservation and environmental
protection
Reduction of noise pollution during use
Any loose parts (e.g. chains) should be attached to prevent unnecessary noise.
Energy-efficient use
The tines of the Grassland Combi should not penetrate into the soil deeper than necessary. By
doing so, the towing vehicle is not unnecessarily strained and fuel can be saved.
Recyclable raw materials during disposal
Many parts of the Grassland Combi are made of steel or spring steel (such as the frame, tine
section, tines, ...) and can be accepted and recycled by a waste disposal plant.

The holder for the warning sign with lighting (optional equipment) is mounted on the carrier for
the roller and should be positioned vertically to the road.
On the implement side, the top link must be firmly attached - never in the elongated slot of the
implement.
If you are using a ground wheel for the pneumatic spreader with a side bracket, please remove
it and hang it on the frame so that the transport width of 3 m is maintained.
After field operation, the roller of the GK 400 M1 must be cleaned to prevent soil residues
adhering to the roller from falling on the road.
14.2 Transport on public roads (most important specifications)
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 the respective country-specific STANDARDS).
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!
If the transport width of the GK 400 does not comply with the road traffic regulations of the
respective country of the operator, the GK 400 must be transported on a flatbed trailer.
14.3 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 maximum permissible total load, the 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:

Weight calculations
1. Calculation of the minimum front ballast for rear-mounted implements GV min:
This result is entered in the table on the next page.
2. Calculation of the minimum rear ballast for front-mounted implements GH min:
This result is also entered in the table.
3. Calculation of the actual front axle load Tv tat:
If the required minimum front ballast (GV min) is not reached with the front-mounted implement
(GV), the weight of the front-mounted implement must be increased to the weight of the minimum
front ballast!
Now enter the calculated actual front axle load and the permissible front axle load
specified in the tractor operating manual in the table.
4. Calculation of the actual total weight Gtat:
If the required minimum rear ballast (GH) is not reached with the rear-mounted implement (GH min),
the weight of the rear-mounted implement must be increased to the weight of the minimum rear
ballast!
Now enter the calculated total weight and the permissible total weight specified in the table in the
tractor operating manual.
5. Calculation of the actual rear axle load TH tat:
Enter the calculated actual rear axle load and the permissible rear axle load specified in the table in
the tractor operating manual.
