5.2 INCONVENIENCES, CAUSES AND REMEDIES
INCONVENIENCES
CAUSES
REMEDIES
Drivelines noisy when
lifting.
1)
Incorrect connection to 3-point hitch.
2)
Lifting height too high
1)
Position the 3rd point parallel to the lower lifting
links.
2)
Limit the lifting travel.
If the problem persists, disengage the PTO when
lifting.
Machine noisy during
operation.
1)
Machine tilts too far forwards or backwards
during work.
1)
Lengthen or shorten the 3rd point so as to set
the machine horizontal in the work position (the
tractor’s PTO and the machine must be sensibly
parallel to each other).
E x c e s s i v e p o w e r
draw.
1)
Work depth too deep.
2)
Rotation frequency of machine too high.
3)
Ground speed too fast.
4)
Front or rear levelling bar incorrectly positio-
ned.
1)
Reduce the work depth by adjusting the roller.
Do not work deeper than necessary.
2)
Reduce the rotation rate of the gearbox (op-
tional gears).
3)
Reduce the ground speed.
4)
Raise or remove the levelling bar.
S o i l c l o d s t o o l a r-
ge.
1)
Excessive build-up of vegetation around knives.
2)
Ground speed too fast.
3)
Rotation rate of machine too low.
4)
Levelling bar not fi tted.
1)
Remove the residues.
2)
Reduce the ground speed.
3)
Increase the rotation rate of the optional ge-
arbox.
4)
Mount the levelling bar.
S o i l c l o d s t o o
small.
1)
Rotation rate of machine too high.
2)
Ground speed too slow.
3)
Rear levelling bar too low.
1) Reduce the rotation rate of the gearbox (optional
gears).
2)
Increase the ground speed.
3)
Raise or remove the rear levelling bar.
Excessive wear on knives
and knife supports.
1)
Harrow rotation speed too fast.
1)
Reduce the rotation rate.
1)
Use knives with hard facings.
1)
Raise the levelling bar.
Machine clogged with soil
between the rotor and
levelling bar.
1)
Levelling bar installed behind in wet conditions.
1)
Remove the levelling bar.
Faulty Packer roller ope-
ration (clogging, jamming
or caked soil).
1)
Scrapers mounted badly or too worn.
2)
Scrapers clogged with plant residues.
3)
Scraper crosspiece badly positioned.
1)
Adjust the roller scrapers in a better way.
Use coated scrapers if the wear is too evident.
2)
Clean the scrapers by turning them.
3)
The scraper crosspiece must always be turned
forwards. Wear must only be recovered by the
sliding movement of the scrapers.
Standard Packer roller
jammed by soil caked in
front of roller.
1)
Sandy soil.
1)
Slightly lengthen the 3rd point.
1)
Reduce the ground speed.
1)
Use a larger diameter roller if necessary (when
possible)..
Cage roller clogged.
1)
Wet conditions.
2)
Excessive load on roller (built-in seeding attach-
ment).
1)
Disassemble the additional tubes of the cage
roller.
2)
Use a Packer roller.
