Dif fi culty in making the se-
eding elements penetrate
the soil.
Blocking of seed delivery
tubes.
Problems with covering the
seeds.
1) On compact and dry soil , lower the machine’s
height from the ground by slackening the nuts
that compress the element pressure adjusting
springs (A, Fig. 1).
2) If the problem persists after the fi rst solution
has been carried out, ballast the frame of the
machine to increase its weight as described
earlier in this manual.
3) Use the required cutter disc.
1) There is not suf fi cient air to carry the seeds.
Increase the oil pressure using the three-way
regulator (B, Fig. 2) - this will increase the
quantity of air.
2) The number of revs of the tractor is not
compatible with that of the step-up gear in
use.
3) During the sowing starting and planter lowering
manoeuvre on the headland, the tractor revs
fall considerably so losing pressure in the
distribution system.
4) Clogging of the coulters. This happens when
the planter is lowered into the working position
without making it move forwards, and on wet
soil.
5) Check for folds or loops in the seed delivery
tubes.
6) There are foreign bodies in the distributor or
the coulter.
1) The rear seed-covering wheel does not have
enough pressure to move the soil onto the
furrow. Increase the pressure by turning the
adjusting screw (C, Fig. 3)
2) The arm of the rear seed-covering wheel has
sideways play (D, Fig. 4). Slacken the lock nuts
and screw in the screws as shown in Figure
4. When this has been done, tighten the lock
nuts again.
CAUTION: the rear seed-covering wheel
moves the soil tilled by the coulter onto the
seed planting furrow. Therefore the correct
position of the wheel is as shown in Figure
5.
