7.4 LEVELLER (OPTIONAL)
The work of the leveller is
essential to obtain a uniform
seed planting depth.
There are two leveller models;
FLAT or TINES.
The leveller can be adjusted
by operating the spindles
(3), which modify height and
pressure of leveller’s three
sections.
It is recommended to use the FLAT leveller on dry fields and
the TINE leveller on damp fields.
EARTH DRAGGED BY THE LEVELLER SHOULD
NOT PROTRUDE OVER THE PLATE.
WHEN USING PNEUMATIC MACHINES, THE AIR
PRESSURE ALONG WITH ABSENCE OF STOPS
IN THE TINE COULTERS’ SOWING SHOES
WILL CAUSE A GREATER PLANTING DEPTH
THAN ACHIEVED USING CONVENTIONAL MA-
CHINES. AFTER SOME MINUTES WORKING,
CHECK THAT THE PLANTING DEPTH IS ADE-
QUATE.
7.5 SEEDING ARM
There are several types of row; each type is designed for op-
timal sowing depending on the type of land to be sown.
7.5.1 TINE COULTER
A
Fixed tine coulters:
These tine coulters have a
non-adjustable depth, but their
pressure can be adjusted by
using a nut placed in the lower
part of the spring (A). Sowing
depth will be determined by
the adjustable central ratchets.
Adjustable tine coulters:
These tine coulters are aligned
with both the tractor’s and the
seed drill’s wheels. They are ad-
justable levels of depth which
allow the tine coulters to be
lowered:
1-
Turn the nut with a wrench to
lose the screw (B).
2-
Turn the screw stop to control
depth (B).
3-
Tighten the nut to secure the
position (B).
B
C
The row pressure is adjusted by means of the nut (C).
7.5.2 PT
D
Fixed tine coulters:
These tine coulters have a
non-adjustable depth, but their
pressure can be adjusted by
using a nut placed in the lower
part of the spring (D). Sowing
depth will be determined by
the adjustable central ratchets.
