Crackerboard
The crackerboard is mounted in front of the packer rings and is able to make a
processing of the soil in form of a leveling and compression dependent on
how it is adjusted. The crackerboard makes an excellent processing both for
rough plowing as well as after a preceding cultivation of the soil, as the
crackerboard both levels and crushes clods.
Running
The crackerboard is a very flexible component with several possible applica-
tions combined in one component. With a depth set approximately to 3 to 5
cm depending on the type of soil, the tines and their vibrating effect will re-
sult in a crushing of the clods. If the crackerboard is set deeper, it will result
in a larger leveling effect as a small pile will be accumulated in front of the
tines.
Plate 10
The recommended direction of running, which can be used under most condi-
tions, is to adjust the crackerboard so that the tines' angle with the surface of
the ground is at approx. 70°. Working depth must be adjusted to the succeed-
ing crop and the condition of the field. It is not the purpose of the cracker-
board to function as a blade, but on the contrary to make a light cultivation of
the soil. As each tine is able to move individually and hereby give way to lo-
cal resistances, this moreover results in a more regularly seed-bed than what
can be obtained with a leveling plank.
Hydraulics
Hydraulic operation of the crackerboard's depth regulation secures an easy
adjustment, so that running with the optimal depth always can be achieved.
Hereby, variations in the condition of the soil within the same field are of mi-
nor importance, as it can be secured that the crackerboard continuously during
running, works with the preferred amount of soil.
A double-acting extraction point for operation of the crackerboard is required.
