The working pressure of the blade is obtained from a compression spring, this one can be
adjusted with the nut E in figure 16. This will be done having in mind the type and hardness
of the terrain and the amount of cover crop over it. You will also have to keep in mind that
pressure of the spring must not be excessive not allowing the blade to swivel in case of
blocking, (for example with a rock) in which case damages to the planter could occur.
Registration of the fertilizer discs.
The fertilizing units are placed in such a way
that they deliver fertilizer, a side of the seed
line, from 5 to 8 cm. and not in the same line
this is to avoid PHYTOTOXICITY that could
appear during germination.
The ideal depth is 5 or 6 centimeters. To
move the fertilizing unit through the toolbar;
loosen bolt A of the adjusting wedge/chocks,
adjusting them again once registration has
been achieved. See figure 17.
For depth registration, lifting or lowering of the
fertilizing unit can be done by loosening bolt B
to position the shank at the desired height.
The main registration of these fertilizing units are the following:

Pressure of the discs:
Adjusting or loosening the nut C, the pressure spring can be
compressed or de-compressed to adjust the pressure according to soil hardness.

Depth of fertilizer placement:
By moving the lever D the height of the semi-
pneumatic wheel is adjusted, into 9 different positions for depths from 1 to 9 cm this
moves from 1 centimeter from position to position.
Keep in mind that the height of the fertilizing unit will affect not depth of application
directly, BUT it will affect the pressure that the spring will make over the terrain.
Special attention must be kept, to not exceed the unit´s limits. The pressure spring
must not be forced beyond it´s limits. If necessary the height of the shank may need
to be adjusted.
If you will perform maintenance or registration tasks under the planter:
Place all locks in the elevation cylinders and set correctly the frame support stands.
