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 24).
- If necessary, adjust the scraper plates so that they are in
contact with the roller and tighten the screws (torque 8
daNm / 50 ft.lbs) . Make sure that the scraper plates
only lightly touch the roller and do not interfere with
its rotation
.
- Also make sure that the scraper plates (P) are well
centred with regards to the stud rows (E) (photo 31). The
scraper plate supports (S) are equipped with oblong
holes enabling to recentre them by sliding them cross-
wise at the screw level (V)
(torque 10 daNm / 74 ft.lbs) .
c) Cleaning the scrapers
In case of crop residue build-up, it is recommended for cleaning that the scraper be pivoted backwards around
the 2 upper bolt holes (R) (figure 28, page 24). To do this, untighten the 4 lower bolts (R) and release the 2 adjusters
(Q) after loosening their self-locking nuts (S) (photo 30).
To ease pivoting of the scraper bar towards the rear, use a lever in holes (L) (photo 30) placed at each side of the
scraper bar (H).
C) CRUMBLER ROLLER : 2,50 m - Kit No. 121 6670
3,00 m - Kit No. 121 6680
The crumbler roller is ideal for dry and slightly humid conditions. It is made up of fixed welded tubes (F) and
removable bars (G), held in place by round support rings (figure 32, page 26).
With removable bars in place :
Recommended in dry conditions for fine tillage and levelling with good ground packing.
Without removable bars in place :
Recommended in more humid ground, less risk of roller clogging. Tillage and levelling are coarser.
Bars can be removed as follows :
- Remove inside roll pins
- loosen the bars using a hammer
- pull out the bars.
Fit the 2 adjusters (Q) (photo 30). Using the 2 nuts (S)
on the adjusters, bring the scraper bar towards the
roller until it is almost bottomed-out in the 2 slots of the
support arms (D) (photo 30). Then tighten the 6 bolts
(R) to a torque of
22 daNm / 160 ft.lbs , and if required
adjust the position of the scraper plates (P) as shown
thereafter.
Then mount the complete roller assembly with arms
(A) on the roller arm brackets (K) by means of 2 pins
(X) secured with 2 self-locking screws (J) (M10 x 16)
(photo 23, page 22).
