Quality for Professionals
The two front tine rows tear up the sod. The rear tine rows 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 bottom holes.
On soft soils or wet conditions, you can have only the rear tines working by adjusting
the series of holes higher up.
After this adjustment, you also have the option of changing the work pattern of the
rear tines.
For this purpose, you can select 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 sod is dense
and intense tillage is required, the tines should be positioned more steeply (Fig.: 14).

Levelling board
The levelling board eliminates mole hills after the winter and serve to roughly level
the grassland. The height should be adjusted so that it runs along the sod 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.

Turning at the headland
1.
Turning with the roller:
When turning at the headlands, first the lower links are raised, then the roller
is pressed down so that the GP 600 M1 is running on the roller. It is
necessary to raise the lower links when driving with a very aggressive tine
position.
When driving with control hydraulics, the lowest control height must be
limited just below the normal working depth, otherwise the control hydraulics
would be lowered at the front when lifting.
If the tractor does not have headland management, we recommend turning
with the roller.
