Nylon scraper plate
- Packer PK2 roller: Nylon scraper plate
(Part no. 52570200).
- Maxipacker roller: Nylon scraper plate
(Part no. 52592300).
The nylon scraper plate is permanently in contact with
the roller tube for cleaning it.
The nylon scraper plate is particularly well suited for
light, silty or chalky soils, or soils with a small amount of
plant residues or stones.
Fitting and adjusting the nylon scraper plate:
- Place nylon plate between 2 metallic scraper plates:
• Packer PK2 roller (Part no. 52532130).
• Maxipacker roller (Part no. 52598910).
- The nylon scraper plate must protrude the metallic
scraper plates by approximately 10 mm (0.4’’).
The nylon plate is reversible for longer service life.
Side deflector anti-ridging plate adjustment
The deflector anti-ridging plate is factory fitted in the
forward position (1) and medium height position (2).
The deflector anti-ridging plate position must be adapted
to:
- The working depth.
- The blade wear.
The lengthways position of the deflector anti-ridging
plate must be adapted to:
- The position and type of roller.
Remove bolts (3).
Adjust side deflector anti-ridging plate in the required
position.
For safety reasons, it is not allowed to fold
the side deflectors over the trough.
The anti-ridging plates must be positioned at the
nearest of the roller, without interference.
Adjust both sides to the same setting.
