b) Adjusting the scraper plates
- The hard coated thick scraper plates have been
factory pre-set on a reference roller. Therefore, they
are nearly in the correct working position after
mounting the scraper bar (paragraph a, page 19).
When the machine is attached to the tractor, always
check that the roller can rotate freely.
- If necessary, readjust the scraper plates in order to
bring them close to the roller and tighten with screws
(V) (photo A, page 19) (torque 8 daNm / 60 ft.lbs).
Also check that the scraper plates are only slightly in
contact with the roller’s highest point when rotating so
that they don't interfere with it’s rotation.
- Also make sure that the scraper plates (P) are well
centred with regards to the stud rows (E) (photo C).
The scraper plate supports (S) are equipped with
oblong holes enabling to recentre them by sliding
them crosswise at the screw level (V) (torque 10
daNm / 75 ft.lbs).
When the scraper plates are replaced fit the new scrapers in the original position with the hard coating downwards.
c) Cleaning the scrapers
In case of crop residue build-up, it is recommended for cleaning that the scrapers be pivoted backwards around
the 2 upper bolt holes (R) (photo A). To do this, untighten the 4 lower bolts (R) and release the adjusters (Q) after
loosening their self-locking nuts (S) (photo B).
To ease pivoting of the scraper bar towards the rear, use a lever in holes (L) (photos A and B) placed at each side
of the scraper bars (H).
