To adjust the scrapers of the depth adjustment wheels,
operate on the screws (1, Fig. 6.35). They need to be adjusted
to be at 3-4 mm away from the wheel.
THE SCRAPER MUST NEVER BE IN CONTACT
WITH THE DEPTH CONTROL WHEELS.
Metering unit K is equipped with two seed discs. Each one
has two scrapers, one exterior and one interior.
To adjust the seed disc’s scrapers, follow these steps:
1-
Take apart the depth adjustment wheel using the screw
(2, Fig. 6.36).
2-
Loosen the screws (3, Fig. 6.36).
3-
Place the interior and the exterior scrapers so that they keep
a distance of 2 millimeters from the seed disc, without being
in contact with it.
4-
Repeat the former steps to adjust the two scrapers of the
seed disc placed on the other side of the metering unit.
PERFORM THIS OPERATION WITH THE PLANTER
IN RAISED POSITION.
6.8 PRESSURE OF THE METERING UNIT
ONTO THE GROUND
The pressure device assembled in each metering unit allows
to adapt the machine to several kinds of terrain.
The purpose of this device is to increase or decrease the
pressure exerted by the unit on the ground, to alter its
penetration capacity.
Operate on the lever (A, Fig. 6.37) to modify the pressure
of the unit onto the ground. Depending on the lever’s
position, the pressure exerted by the metering unit will
increase or reduce; The following table shows the pressure
in Kg for each lever’s position (Fig. 6.38).
