8OPERATING MANUAL
8.1 MOUNTING ON THE TRACTOR
The air pressure in the rear tractor tyres should be 0.8 bar during operation.
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. The lower link pins must be inserted in the
upper bushing and the lower link ball must be secured against lateral slipping by the two spacer
bushings (Figure 2). The spacer bushings can be found in the toolbox, on the right in the roller frame.
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).
After coupling, the parking support (Figure 3) is stowed in the shaped
tube of the roller frame (Figure 4).
When the seeder is mounted, the rear parking support must also be
folded up (Figure 5).

12.3 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 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. The
necessary ballast weight as well as the actual axle loads can be determined using the following formulas:

16
Specifications:
Figure 7

the lower link ball
d
Distance from the centre of the lower link ball to the
centre of gravity of the rear-mounted implement
Weight calculations:
1. Calculation of the minimum front ballast for rear-mounted implements GV min:
This result is entered in the table under Point 12.3.1.
2. Calculation of the minimum rear ballast for front-mounted implements GH min:
This result is also entered in the table under Point 12.3.1.
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

14 DECOMMISSIONING, STORAGE AND DISPOSAL
14.1 DECOMMISSIONING THE IMPLEMENT
To ensure that the implement remains fully functional, even if it is out of operation for longer periods of
time, it is important to take precautions for storage: To do so, observe Point 14.2.
14.2 STORAGE OF THE IMPLEMENT
The implement must be stored in a dry place protected from weather conditions to ensure that it
remains functional even if it is stored for a longer period of time.
The parking surface must be suitable for parking the implement. The ground must be firm and level,
so that the stands do not sink in and the Grassland Roller does not roll away.
To ensure safe parking of the implement, lower the stand of the Grassland Roller.
The stand must be secured with a spring cotter on the pin to prevent accidental loosening.
Secure the implement against unintentional rolling away.
Nothing may be deposited or stored on the implement.
The Grassland Roller must always be parked and stored in a secured area. Unauthorized use of the
implement must be prevented.
14.3 DISPOSAL
Disposal of the implement must be performed according to the local disposal regulations for implements.
15 CROP CULTIVATION TIPS WHEN USING THE
GRASSLAND ROLLER
Seedbed preparation is always required before reseeding. With its thorough and effective mode of action,
the GW 250/300 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 the GW 250-400 M1, such as
Regulation of the water balance
Reconsolidation and
Pressing down the seed
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".
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.
With the GW 250-400 M1, we counteract this disadvantage with a roller that presses down the seed and
therefore improves soil contact. This allows the seed to germinate more rapidly and the risk of desiccation
is reduced.

19
The optimal forward speed and the adjustment of the 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.
