7.5 Depth setting
7.5.1 Depth of fertiliser placement
In the field the depth guidance of the machine is accomplished by the packer and
the support wheels.
The working depth of the tines and thus the depth of the fertiliser placement is set
by the height of the machine.
Ø
Adjust the depth at the rear with clips on the packer cylinders and at the front
on the arms of the support wheels. The ratio of aluminium clips to working
depth is approx. 1:3. If a clip of 1 cm thickness is removed, this corresponds to
approx. 3 cm working depth, depending on soil conditions.
Ø
Align the tine frame parallel to the ground. Insert the required number of alu-
minium clips on the front support wheels for this purpose. For machines with
swinging drawbar hitching clips must also be applied to the piston rods of the
hydraulic cylinders on the articulated drawbar. With tractor link arm hitching,
the height of the two-point on the tractor must be corrected, if necessary.
NOTE
The fertiliser placement depends on the conditions in the field and
can therefore only be adjusted during use.
Ø
Check the placement when starting work and regularly during use.
7.5.2 Depth of the levelling discs
WARNING
