ADJUSTMENTS
6.9 SCRAPER PROSEM K
Metering unit PROSEM K is equipped with scrapers in:
- Depth adjustment wheels (A, Fig. 6.70).
- Seed discs (B, Fig. 6.71).
To adjust the scrapers of the depth adjustment
wheels, operate on the screws (1, Fig. 6.70).
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 the-
se steps:
1- Take apart the depth adjustment
wheel using the screw (2, Fig. 6.71).
2- Loosen the screws (3, Fig. 6.71).
3- P
lace 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 me-
tering unit.
PERFORM THIS OPERATION WITH THE PLANTER IN RAISED POSITION.
IMPORTANT: BE SPECIALLY CAREFUL WHEN DISASSEMBLING THE WHEELS. DEPENDING ON
THE SIDE OF THE MACHINE, THE SCREWING DIRECTION OF THE WHEELS’ SCREWS IS LEFT OR
RIGHT. THIS PREVENTS THE WHEELS’ SCREWS FROM BEING UNSCREWED DURING WORK.
