b) Adjusting scraper plates
- Slightly loosen fixing bolts (V) of the scrapers (P) so that they slide freely (photo 10).
- Check that their position is central relative to the rows of roller studs. The scraper supports (M) have elongated
holes to allow readjustment if necessary.
- After having checked that the scraper assembly is in its furthest forward position (photo 10), position scraper
plates one at a time so that they are all in contact with the roller. Retighten bolts (V) (photo 10). Make sure that
the plates only lightly touch the roller and do not interfere with its rotation.
c) Cleaning the scrapers
In case of crop or soil build-up, to clean, it is recommended that the scraper assembly is pivoted to the rear around
the two upper bolts (R) (one on left-hand side of scraper assembly and the other on the right) (photos 10 and 11).
- Loosen the self-locking nuts (S) (photo 11).
- Release the two eyebolts (Q).
- Remove the two lower bolts (R) (one on left-hand side of scraper assembly and the other on the right).
- To facilitate pivoting the scraper assembly, use a lever in each of the two holes (L) situated at each end of the
connecting tube (H) (photos 10 and 11).
a) Assembly of the packer roller and scrapers
When assembling the roller, take particular care
concerning the direction of rotation. The direction of
rotation is indicated on the decal affixed to the side of
the roller.
Fit the roller and the scraper bar holders (D) onto the
2 swinging roller arms (B) using the bearing housing
and the 8 screws (U) (torque to 10 daNm / 74 ft.lbs).
Then bolt the scraper bar (H) onto holders (D) using
the 4 screws (R). Do not fully tighten these bolts at
this stage. Check that all the cleaners (P) of the
scraper are in the retracted position.
Position the 2 eybolts (Q) (photo 11).
Using the two nuts (S) tighten against the tensioners
to pivot the scraper towards the roller until the two
elongated holes almost butt out (photo 11). Thereaf-
ter tighten the four bolts (R) and adjust the scraper
plates (P) as described below.
