assembly
Check the singulator, seed plate and seed
ejector assembly. Always use these components
to match the type of culture that are about to
be sowed.

Check the condition of the seed ejector and
replace it if worn out. Always use a seed ejector
to match the type of culture that are about to
be sowed.
System spring
Check if the spring is installed correctly, pushing
the singulator to the center of the disc blade
direction.
Excessive wear on
the seed singulator
Check and replace the seed singulator. Always
use a seed singulator to match the type of
culture that are about to be sowed.
Vacuum excess on
the system
Reduce the vacuum pressure and check if there
is any improvement on the seed deposition. It is
recommended to adjust the pressure according
to the culture need, aiming for a great seed
distribution on the soil.
Equipment speed
The equipment speed is one of the main
factors that cause problems on the number of
plants. Always keep the ideal plantation speed.
Marchesan recommends a speed of 5 - 7 km/h.
