B) MAXIPACKER ROLLER
2,50 m - Kit No. 121 6690
3,00 m - Kit No. 121 6700
This roller is suitable for all soil types and especially humid and sticky soils. It provides an efficient ground packing,
a good levelling and crumbling.
Due to its large diameter cylinder, it provides a large ground contact area, hence reduced sinking and less
resistance to rolling, meaning a reduced traction power is needed. The scraperbar is part of the maxipacker roller.
The scraper plates located between the rows of studs ensure the cleaning of the roller. They are hard coated to
further increase their service life.
In case of blocking with crop residues, the scraper bar can be easily pivoted to permit cleaning.
a) Fitting the maxipacker roller and its scraper
(figures 28 and 29 and photo 30).
When fitting the roller, be sure to check its direction of rotation. The direction of rotation is indicated by a sticker
on the side of the roller (see arrow on figure 28).
Using 8 bolts (U) and M12 nuts and mount roller arms (B) and scraper bar arms (D) on the bearing housings (T)
placing spacer (N) as shown on drawings 24 and 25
(torque 10 daNm / 74 ft.lbs)
.
Then fit the swinging arms (A) on roller arms (B) with 6 bolts (C) and M16 nuts using the 3 holes (C)
(torque 22
daNm / 160 ft.lbs)
(fig. 26, page 23).
Then fit scraper supporting bar (H) onto the 2 support arms (D) with the 6 bolts (R). Do not tighten the bolts at this
stage (figure 28).
b) Adjusting scraper plates
- Slightly loosen fixing bolts (V) of the scrapers (P) so that they slide freely (figure 24, page 23).
- Check that their position is central relative to the rows of roller teeth. The scraper supports have elongated holes
to allow readjustment if necessary.
- After having checked that the scraper bar is in its furthest forward position (photo 27, page 23), position scraper
plates one at a time so that they are all in contact with the roller. Retighten bolts (V) to
8 daNm / 50 ft.lbs
(figure
24, page 23).
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 be pivoted to the rear around
the two upper bolts (R) (photo 27, page 23).
- Loosen the self-locking nuts (S) (photo 27, page 23).
- Release the two eyebolts (Q).
- Remove the two lower bolts (R) (photo 27, page 23).
- 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) (photo 27, page 23).
