The combined action of the parallelogram (E) and the
float wheels (F) ensures the ideal weight and that the
planting unit is properly adapted to the soil type (soft,
compact, etc.).
The adjustment unit (A) can be mounted in either posi-
tion (A1) or position (A2).
The adjustment unit is usually mounted in position
(A1).
With the unit in position (A1) the weight on the packing
wheels can be reduced.
With the unit in position (A2) the weight on the packing
wheels can be increased.
Alternatively turn the handwheel (C) clockwise or anti-
clockwise and tighten or loosen the nut (D) to exercise
the ideal weight on the packing wheels.

adjusted by the user according to requirements.
