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.

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.
