CAUSES
1) The stroke of the planting unit is short.
2) The planting depth is not the same in all
the planting units.
3) All the planting units are set in the same
manner, but seed furrows are at different
depths.
4) The planting units tend to "bounce" on the
soil, thus losing the required contact.
5) All the planting units are set in the same
manner, but they move large amounts of
soil.
6) When the twin element is fitted, the front
and rear seed distributors have different
planting depths.
7) The soil has not been prepared properly.
8) Planting is performed at steep gradients.
9) The height of the clod clearer is low.
10) The compression wheel and seed-
covering wheels are not suitable for the
type of soil.
1) The seed is not released from the hopper.
2) The diameter of the holes in the disc is not
correct for the type of seeds in use.
3) Holes in the disc are clogged.
4) The seed supply door is not sufficiently
open.
5) After a short time, the seed is not released
from the hopper.
6) The disc feed hub is tarnished.
1) The selectors in the different distributors
are not set equally.
2) Proper selection is not possible with any
adjustment.
3) Selection is correct during testing, but it
is not during planting operations.
4) Selection is not sensitive to the cam
adjustment.
1) The seed ejector is not running.
2) Seeds are released in a random and
disorderly manner.
1) The vacuum pump is running at
operating conditions, but vacuum is
missing in the pipes.
2) The cardan shaft rotates, but there is no
aspiration.
3) The aspirator revolutions drop.
USE AND MAINTENANCE
1) Check that in the operating position the indicator
on the stroke bar matches the centre of the slot.
2) Check that the planting depth is set in the same
manner in all the planting units.
3) Check that all the earth-opening coulter blades
have the same depth (distance between top and
plates).
4) Check that the spring-type shock absorber is
tensioned equally in all the planting units, and
that tensioning is not excessive (the element is
excessively unloaded).
5) Check that all the clod clearers are set at the
same height. If this is not the case, lift them.
6) Put the coulters on a flat horizontal surface and
check that they are perfectly parallel with the
ground: adjust the third hitch, if necessary.
7) Prepare the soil thoroughly.
8) When working at gradients exceeding 20%,
planting may not be regular.
9) Raise the clod clearer: it must be set as
described in the instruction manual.
10) Replace.
1) Remove possible residual seeds along the pipe
or in the hopper: thoroughly clean the distributor.
2) As a general rule, the diameter of the hole must
be approx. half or 1/3 the diameter of the seed.
3) Always clean the discs and check that all the
holes are clear.
4) Move the door regulating seed supply upwards.
5) Install a seed agitator, especially if the seeds are
not coated.
6) Use anti-seize products to release the hub.
1) Check that the selectors are set equally in the
different distributors.
2) Check that the selector is matched with the
correct disc (single, double, etc.).
3) Run a planting test and adjust the selectors
according to the actual working speed.
4) Check for excessive wear (cam plate
disappears).
1) Check that the seed ejector can run freely
and is clear from clogging or residues.
2) Check that the ejector is matched with
the correct disc (single, double, etc.).
1) Clean all the air pipes; clean the filter;
check that all the caps are fitted; check
that the seed aspirator cock is closed.
Check the pipes and ensure that they do
not leak.
2) Check that the vacuum pump is
operating correctly, the pulleys are
tensioned properly and the belt is in good
condition.
3) Check the following:
g
SOLUTIONS
a) belt tensioning;
b) revolutions of the tractor's power take-
off;
c) air pipes in the planting units for
breakage.
