Crackerboard
The crackerboard is mounted in front of the packer rings and is able to make a pro-
cessing of the soil in form of a leveling and compression dependent on how it is ad-
justed. 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 applications
combined in one component. With a depth set approximately to 3 to 5 cm depend-
ing on the type of soil, the tines and their vibrating effect will result 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.

The recommended direction of running, which can be used under most conditions,
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 succeeding crop and the
condition of the field. It is not the purpose of the crackerboard 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 local resistances, this moreover re-
sults 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 ad-
justment, 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 minor 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.
