2) PACKER ROLLER
HR 5002 DR / 5002 DR - S : Code 123 6720, quantity 2
HR 6002 DR / 6002 DR - S : Code 123 6730, quantity 2
This roller is particularly intended for use in wet or sticky soils. Efficient packing, proper levelling and good crumbling
are achieved.
The scraper bar forms an integral part of the roller packer.
These scrapers, placed between the rows of studs, ensure that the roller is cleaned.
a) Installing packer rollers and scrapers (photos 10 and 11)
When fitting the rollers, be sure to check their direction of rotation (see arrow on photo 10). (The direction of rotation
is also indicated by a sticker on the side of the roller).
Fit the rollers and scraper supports (D) to the 2 arms (B), using the guide housing and the 8 bolts (U). Then fit scraper
supporting bar (H) onto the 2 support arms (D) with the 4 bolts (R). Check that all the scraper plates (P) are fully
retracted (towards the rear). Fit the 2 adjusters (Q) photo 11).
Using the 2 nuts (S) on the adjusters, pivot the scraper bar towards the roller until it is almost bottomed-out in the
2 slots (photo 11). Then tighten the 4 bolts (R) to a torque of 22 daNm / 160 ft.lbs, and adjust the scraper plates
(P) as described thereafter.
b) Adjusting the scraper plates
- Slightly loosen the 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 teeth. The scraper supports have slotted holes to
allow readjustment if necessary.
- After checking that the scraper bar is in its furthest forward position (photo 11), position the scraper plates one
at a time so that they are in contact with the roller. Retighten bolts (V) (torque 6 daNm / 44 ft.lbs) (photo 10). Check
that the scrapers only lightly touch the roller, and do not interfere with its rotation.
If hard coated scrapers are used ensure that the coating is towards the front and downwards.
c) Cleaning the scrapers
In case of crop residue build-up, it is recommended for cleaning that the scrapers are pivoted backwards around
the 2 upper bolt holes (R) (photo 10). To do this, remove the 2 lower bolts (R) and release the 2 adjusters (Q) after
loosening their self-locking nuts (S) (photo 11).
To ease pivoting of the scraper bar towards the rear, use a lever in holes (L) (photos 10 and 11) placed at each
side of the scraper bar (H).
