4.7. Using the levelling boards
The purpose of the levelling boards is to crush clods and even out the level changes of the surface of
the field. A correctly adjusted levelling board crushes and mills clods but does not gather a large wall of
soil in front. This also creates fuel savings as the excessive use of the levelling board requires a great
deal of power from the tractor.
Basic adjustment:
The rod of the harrow cylinders is threaded so that the sections can be adjusted to the same position.
The adjustment is carried out by loosening the lock nut (36 mm key) and rotating the piston rod (point
2, 24 mm key). Lengthening the rod raises the front levelling board and shortening it lowers the board.
Before making any adjustments, we recommend to tillage for a while and synchronize the levelling
board. This ensures that the misalignment of the levelling boards is not caused by the differences
between the cylinders.
Basic height adjustment:
Changing the height level can be done by opening two bolts from each attachment brackets (point 1
above). With the high position, the front levelling board is more vertical and it breaks, for instance,
slaked surface better. With the low position, the levelling board mills the clods smaller more efficiently.
Factory setting is at the high position. It is recommended for almost all conditions. Lower position can
be considered on very shallow cultivation.
Basic height levels of the front levelling board. Low – high.
