10.3 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 (2 pcs.)
locking pins, crank the levelling plate to the desired height, and fix it
again with the 2 pins. (Fig. 18)

TIP!
Remove the pin on the right first, and then the left pin, so that you can lift the levelling
plate more easily with the crank.
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. 19).

10.4 Use of individual tools
With GK 250/300 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.
