4.9 INCONVENIENCES,
Inconveniences
Drivelines noisy when lifting.
Machine noisy during operation.
Excessive power draw.
Soil clods too large.
Soil clods too small.
Excessive wear on knives and knife supports.
Machine clogged with soil between the rotor and levelling bar.
Faulty Packer roller operation (clogging, jamming or caked soil).
Standard Packer roller jammed by soil caked in front of roller.
Cage roller clogged.
CAUSES AND REMEDIES
Causes
Incorrect connection to 3-point hitch.
Lifting height too high.
Machine tilts too far forwards or backwards during work.
Machine with insuffi cient side stability.
Work depth too deep.
Rotation frequency of machine too high.
Ground speed too fast.
Front or rear levelling bar incorrectly positioned.
Excessive build-up of vegetation around knives.
Ground speed too fast.
Rotation rate of machine too low.
Levelling bar not fi tted.
Rotation rate of machine too high.
Ground speed too slow.
Rear levelling bar too low.
Mower rotation speed too fast.
Levelling bar installed behind in wet conditions.
Scrapers mounted badly or too worn.
Scrapers clogged with plant residues.
Scraper crosspiece badly positioned.
Sandy soil.
Wet conditions.
Excessive load on roller (built-in seeding attachment).
Remedys
Position the 3rd point parallel to the lower lifting links.
Limit the lifting travel.
If the problem persists, disengage the PTO when lifting.
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).
Stabilize the machine on a level with the lower lifting links.
Reduce the work depth by adjusting the roller.
Do not work deeper than necessary.
Reduce the rotation rate of the gearbox (optional gears).
Reduce the ground speed.
Raise or remove the levelling bar.
Remove the residues.
Reduce the ground speed.
Increase the rotation rate of the optional gearbox.
Mount the levelling bar.
Reduce the rotation rate of the gearbox (optional gears).
Increase the ground speed.
Raise or remove the rear levelling bar.
Reduce the rotation rate.
Use knives with hard facings.
Raise the levelling bar.
Remove the levelling bar.
Adjust the roller scrapers in a better way.
Use coated scrapers if the wear is too evident.
Clean the scrapers by turning them.
The scraper crosspiece must always be turned forwards.
Wear must only be recovered by the sliding movement of the
scrapers.
Slightly lengthen the 3rd point.
Reduce the ground speed.
Use a larger diameter roller if necessary (when possible).
Disassemble the additional tubes of the cage roller.
Use a Packer roller.
