6.2.4.1 SM MODEL
This model is fitted with two types of coulter:
FIXED COULTERS
These coulters are not height-adjustable. Consequently, the
sowing depth will be defined by the adjusters on the coulter
unit's chassis (see section 6.2.1 DEPTH ADJUSTERS).
It is only possible to change the coulter pressure by adjust-
ing the nut at the top of the spring (1, Fig. 6.15).
THESE COULTERS HAVE A DUAL SPRING. RE-
MOVE THE INNER SPRING TO REDUCE SUB-
STANTIALLY THE PRESSURE EXERTED BY THE
COULTER.
The coulter is fastened to the bracket by a special SOLÀ bolt
(2, Fig. 6.15) with a self-locking nut. The coulter's side clear-
ance is adjusted using this nut.

FIXED
HEIGHT-ADJUSTABLE COULTERS
These coulters are aligned with the wheels of the tractor and
seed drill.
IMPORTANT:
IT IS ADVISABLE TO ADJUST
THESE COULTERS IF THE RUTS ARE VERY DEEP.
Adjust the spring nut to set the pressure exerted by the coul-
ter on the soil (1, Fig. 6.16).
THESE COULTERS HAVE A DUAL SPRING. RE-
MOVE THE INNER SPRING TO REDUCE SUB-
STANTIALLY THE PRESSURE EXERTED BY THE
COULTER.
These coulters are fastened to the bracket by a special SOLÀ
bolt (2, Fig. 6.16) with a self-locking nut. This nut is used to
set the coulter's clearance.
These coulters' depth can be adjusted individually, enabling
the coulters to be lowered to adjust their height, as follows:
1-
Remove the bolts and nuts (3, Fig. 6.16).
2-
Place the coulter in the desired position.
3-
Insert the bolts and nuts in the new position (3, Fig. 6.16).
