5.3 Positioning the extensions
The extensions can be in a fixed position or in a floating position. The floating position is
used to follow the differences in level of the ground in order to obtain even sowing in liaison
with the optional wheels on the extensions.
The PENTASEM must be placed on flat ground in unfolded position when switching from
the fixed position to the floating position. Remove the pin from the swivel cylinder of the
extensions and direct the shims (see drawing below).
Give attention to the adjusting of the lower stop according to the desired position of
the extensions.
Never switch from the floating or fixed position with the machine folded
Positioning the shims
