Side 22
The working depth of the Crackerboard
is hydraulically adjustable. The tine
angle is adjusted manually by means
of the spindles (A). The sides of the
spindles are marked with numbers to
facilitate uniform angle adjustment.
The tine angle will remain set regard-
less of the depth, since the tines are
mounted in a parallelogram formation.
•
For an
aggressive tine
(vertical tine), shorten the spindles.
•
For a
passive tine
(tine lying down, lengthen the spindles.

To adjust the angel of the tines, the Crackerboard must be i upper position.
Adjust tine angle to accommodate different field operations. If the tine is set ag-
gressively and the penetration depth is set in the upper soil layer, the maximum
amount of vibrations will be achieved to finely crush clods. This setting is recom-
mended for most field work.
If the tine is lying down, it can more easily avoid obstacles. The point of the tine is
also in a more vertical position, which gives a more uneven field surface.
Operating and driving instructions
The Crackerboard is a versatile piece of equipment, with several application possibil-
ities in one unit. At a depth setting of approx. 5 cm, the vibrating power of the tines
will crush clods.

A deeper setting of the Crackerboard
provides a greater levelling effect than
a levelling board, as a small amount of
soil builds up in front of the tines.
The Crackerboard is
not
designed to function as a dozer blade, but rather to perform
light soil cultivation. Since each tine moves independently and responds individual-
ly to land contours, the Crackerboard is easy to tow and requires less adjustment
than the levelling board during operation.
If the Crackerboard sections do not operate at uniform depth, it may be necessary
to “reset” the Crackerboard by raising the board to the highest, top position.
