Troubleshooting guide
TYPE
PROBLEM
CAUSES
POSSIBLE SOLUTIONS
Seed and
fertilizer
spreader
Slippage
Ballasts
Check the liquid ballast on the tires.
Tires inflation
Inflate the tires appropriately.
Tire design
Check and replace worn tires or if they are not
matching the design. Always use equal tires.
Wheels with low
friction on the soil
Check the wheel springs, retighten them and
replace them if necessary.
Sprockets are
not activating
Worn out gears
Check the conditions of the gears and replace
them if they are worn.
Unactive gears
Check if the gears are activated and, if not,
activate them.
Row units
with different
dosages
Different
combination of drive
and driven shafts
Check the combination of drive and driven
shafts on every sprocket.
Oxidized chains
Lubricate and unlock the chains.
Variation on
the suction
pressure
Oscillating turbine
RPM
Check and adjust the pressure as needed. If
the pressure is activated by the PTO, keep
a constant 540 RPM rotation; if the pressure
is activated by a hydraulic motor, check the
working pressure, flow rate and the free return
to the reservoir.
TYPE
PROBLEM
CAUSES
POSSIBLE SOLUTIONS
Fertilizer
spreader
Clogging
Improper operation
by the tractor
operator
Performing maneuvers being the equipment
lowered (either forward or when in reverse
gear) may lead to a clogging on the metering
system.
Product quality
Be sure about the fertilizer quality. Normally
when a product has excess of powder, it may
get in contact with humidity and transform to
a pasty product, thus clogging the metering.
Strange material
inside the fertilizer
metering
Check the existence of strange objects that
may eventually fall inside the hoppers during
the filling process.
Excess
or lack of
fertilizer
Sprockets
Check the drive-driven shafts combination.
Carry out a practical test on the field to
determine the correct amount.
Springs pitch
Check the condition of the springs as well as
their pitch.
Heavy/hard to
turn metering
Lack of lubrication
Check and lubricate the metering mechanism.
Cobbled fertilizer
Clean the fertilizer meterings.
