Check the central lock: it must be well clear;

Lock the central lock after folding.
Hitching to the tractor
∗
It is advisable to extend the 3
rd
point of the tractor in order to give the seed drill a
backward rake of approximately 5 cm. This improves coulter action (Diagram 4).
∗
The tractor hitch arms are to be free.
∗
Check them as they drop to ensure that
the seed drill is resting fully on its wheels
in all conditions. If the hitch does not drop
sufficiently the wheels may skid and the
seed drill will stop sowing.
aligning Sections
Single bar or
articulated seed
drills
The sections are fitted at 90° to the main beam and do not normally require
adjustment.
In the event of a section not following its
sowing line properly, first check whether
the 4 bolts which secure it to the beam
are tightened properly and correct the
alignment as required by placing a shim
between the beam and the hinge bracket
of the section (Diagram 5). (To the left or
to the right, as necessary)
Folding seed drills
When the seed drill is in the operating position, the beams come into contact with
the adjustable stops (Diagram 6).
The stops can be set separately and enable each beam to be set such that the
sections are pulled in a straight line.
Where it is not required to correct all sections as a whole, use the adjustment
procedure set out in A.
If a substantial adjustment has been made and in order to ensure ease of opening
and closing the seed drill, refer also to linkage setting in the next item.
