7.2 INCLINATION OF THE FOLDING PARTS
At the connection point between
the folding parts and the central
chassis, there are adjustable stops
(two each side) which allow the
inclination angle of the folding
parts to change.
1-
Loosen the 2 securing nuts.
2-
Remove the 2 screws.
3-
Place the stop in the desired position.
4-
Insert the 2 screws and tighten them using the 2 securing nuts.
During normal sowing conditions, the folding parts should be slighlty lower
than usual to adapt to terrain irregularities.
In very tilled or loose land, as well as in soils with high humidity, the folding
parts should be levelled to stay horizontal.
7.3 LEVELLER
The work of the leveller is essential
to obtain a uniform seed planting
depth.
The leveller can be adjusted by
operating the spindles (1, fig. 57),
which modify height and pressure
of leveller's three sections.
Earth dragged by the leveller
should not protrude over the
plate.
