III.E - USAGE
After having com leted all safety checks and made sure the harrow is arallel to the
ground, roceed as follows:
• raise the im lement off the ground in order to let the tines start moving without
touching ground to avoid damages
• kee ing the im lement raised, engage the tractor PTO at suggested engine’s revs
• start moving the tractor forward and then gradually lower the im lement
OPERATING TIPS
Pro er ground s eed for harrow will de end u on the ty e of soil and its
conditions. However we suggest not to exceed 5 km/h (3.1 m h)
Lower ground s eed allows to grind the soil with better erformance. In order to obtain a
o osite result roceed more quickly
During the o eration, in order to not cause damages to the harrow,
avoid to steer the im lement and avoid to work in reverse. It is always
necessary to raise the im lement before making a turn or change of
course, otherwise damages to the skid or roller su orts can occur.
The im lement must be used only if equi ed with all its com onents as
su lied by SOVEMA (safety devices included). No com onents can be
modified

III.G TROUBLESHOOTING
During the operation o implement several problems can happen:
UNUSUAL NOISES
During working, i the implement produces unusual noises, the operator must
immediately stop it and ollow these instructions:
• Make sure that there are no broken/bent mechan cal parts
• Check that the gearbox conta ns the correct amount of o l
I the oil level is too low (please see the section “V - MAINTENANCE”), the gears
are not adequately lubricated and i the gearbox continues to rotate will determine
a signi icant increase in oil temperature. This will quickly produce damages to the
gears and bearings
• Check t nes cond t ons
I some o the tines are broken, bent or present excessive wear, the balance o
the rotor will be compromised. During working, the rotating movement o the rotor
will produce vibrations that will inevitably damage and break bearings and welded
parts o the rame. In order to avoid damages, please replace all the tines at the
same time with the new genuine ones supplied by SOVEMA
• Check the lubr f cat on of the gears conta ned n the box
As a consequence o inadequate lubrication, damage to some gears can occur in
short time. Continuing to work in this way can occur the block o the transmission
in short time
• Check the lubr cat on and cond t on of the rotor shafts bear ngs
As a consequence o reduced lubrication, one or both the bearings supporting the
rotor sha t may have broken down. The rotor begins to oscillate producing
excessive vibrations against the rame, producing damages to the welded parts
o the rame

III.G - 2/3
Another possible cause or breaking rotor sha t bearings can be the impact with
heavy objects on the ground such as stones, metallic objects, etc.
Another possible cause or breaking rotor sha t bearings is the improper use o
the implement; esplecially using it at high speed, changes on direction, u-turns
while working
• Check the mplement
During the working i the implement jumps over the soil or vibrates may be that
tines mounting is incorrect or blunt edges o tines are penetrating the soil irst
WORKING ANOMALIES
I a ter the operation the implement ailed to obtain an acceptable tillage, the operator must
ollow these instructions:
• Check t nes
The tines can be worn and less e ective. Please replace them. Use original tines
SOVEMA only.
During the working i the the tines rub along the soil instead o penetrating it,
please advance more slowly.
During the working i the tines are clogged raise the levelling bar in order to keep
clods away the tines
• Check f the work ng depth has been properly set up
The adjustment o the implement may be uneven. Check that roller is parallel to
the soil
• Check gears cond t on after remov ng the frame l d
It is possible that the gears are not in good condition, thus ailing to transmit
enough power to the tines.
I a gear looks marginally damaged, the operator must replace it immediately
• Check f rotors are free from fore gn bod es
It is possible that objects, such as clods, stones, metal parts etc., are attached to
the rotor sha ts or tines prevent it works in the best condition. I it is happened this
above mentioned please remove the oreign parts
• Check advancement tractor speed
A less-than-adequate result can be produced by an incorrect working speed. The
speed must be set up in relation to the rotor turns, type o soil and tractor power.
Advancing too quickly doesn’t allow the tines to grind thoroughly
