Robust frame design
Robust frame design from the cultivator range
Strong headstock from the CLC pro range
The roller arms are linked to the front of the
frame for better dilution of the strains
Rigid version:
-Available in 3m, 3.5 m and 4 m
-100x100x8 mm box section
-Bolted frame concept to avoid weaknesses
Fold version:
-Available in 4m, 5m and 6m
-100x100x8 mm for the extension
-Bolted frame concept to avoid weaknesses
-200x200x10 mm for the central frame
-4 hydraulic cylinders on the 6m version for folding
Strong and reliable bearing
Fully integrated bearing
Oblique contact ball bearing (40°) for high radial and
axial load capacity
No maintenance (no grease nipple)
Hub locked by special washers
Perfect sealing system with 5 lips set-up as a
labyrinth + 1 extra bearing seal + one 0-ring on the disc
side
 Big shaft ø35 mm for heavy load capacity
2 ball bearing with
oblique contact 40°
Shaft ø 35 mm
 Hub nut protected into the disc arm
Seal with 5
lips
The access to the bearing is simple and easy. Only
one nut to remove : it is not necessary to remove the
complete arm
O-ring
2 years warranty due to the reliable bearings
Kverneland heat treated disc
Conical disc for keeping a constant cutting angle
whatever the depth and the disc diameter are.
Good cutting quality even with shallow work (3 to 5
cm).
Good penetration of the disc thanks to the
aggressive angles (not necessary to add weights)
Can work with high stubble (maize, rape, sunflower),
on ploughed lands and can destroy green fertiliser
stubbles without get blocked.
Small notched on the disc to ensure good
penetration, good cutting effect on the whole working
width and small holes in the ground to avoid a pan
profile
 Disc studied for long life time
- Heat treated discs : very high hardness (55-58
HRC)
- Big diameter disc 573mm x 6mm thickness
- Disc 520 mm x 5 mm for more aggressive

Mechanical depth adjustment
The depth adjustment is made with 14 spacers that stops the roller arms to
adjust the depth
A bush is used to maintain the roller weight on the machine
Working depth from 2 to 15 cm
Easy and friendly setting adjustment
Hydraulic depth adjustment
The depth adjustment is made with 14
spacers that stops 2 hydraulic cylinders
(rigid) or 4 hydraulic cylinders (fold)
Working depth from 2 to 15 cm
Easy and friendly setting adjustment
Easy to use the roller weight to improve
the penetration
The machine can be lift up with the roller in
wet conditions
Lateral disc adjustment
The overlapping is adjustable with
spanners delivered with the machine
The discs are able to cut the ground
on the full working width
The overlapping of the disc must be
adjusted depending of the disc size to
ensure the full cut of the soil whatever the
disc diameter is.
Good cutting effect
The disc can not move sideways in cutting
position: the disc has always the same cutting
angle
If the disc hits an obstacle, the disc arm is
able to move sideways and the safety system
works as a 3D auto-reset system
Strong torque of the safety system for high
disc diameter

Competition
Good levelling control
Important : No working discs are used to control the levelling : all of them are working at the
same depth. The lateral levelling is managed by lateral deflectors
 The deflector limits the soil flow in the working width
 They are mounted on parallelogram to follow the ground contour, to retract when stones or
accumulation of straw
 Lateral adjustment for accurate setting
 An axle limits the deflector working depth to avoid damaging it when reverse. Friendly, easy
and reliable. No tools are necessary to adjust it.
 The deflectors have a wearing plate at the bottom
 They are foldable on rigid version
Finger harrow
The finger harrow regulates the soil flow in
a way that the fine soil stays on top layer for
better re-growth of weeds
Fitted on a strong 50x50x5 mm tube
4 different positions available depending
the residues and the soil flow
 The central tine located in the middle of
the 2 rollers avoid any kind of ridges for
perfect levelled surface
Wide roller offer
Actipack roller  560 mm
Make it as aggressive as you want
• Skid and knives between discs clean even in wet conditions.
The knives are cutting bigger clods coming in the disc spacing of
12,5cm leaving a ready seedbed
• Knives pressure can be adjusted as high as the disc pressure to
the ground to make equal pressure through the working width to
achieve a nice and firm seedbed, and can also be put in a non
working position to leave a rough ground surface with more clods
(weather protected)
• Maintenance free bearings with 5 lips labyrinth sealing system +
steel protection cover
• 3 different positions of the knives aggressiveness are proposed +
1 “OFF” position. They are adjusted thanks to the long spanner
• Can work with or without knives
• No limitation in stony conditions
• Discs with aggressive notched shape to ensure good driving
Wide roller offer
Actiring roller ø 540mm
• Light and active due to the skids between the rings that avoid
blockages.
• The knives are cutting bigger clods coming in the disc spacing
of 12,5cm leaving a ready seedbed
• Ring made with L profile.
• Light and strong construction
• Good recompaction (160 kg/m)
•Shaft diameter: 50 mm
Unique knives pressure adjustment
• Knife pressure can be adjustable to ensure a fine crumbled
seedbed or rough surface
•3 different positions for the knives pressure are available. They
are adjusted thanks to the long spanner delivered with the
machine
• Maintenance free bearings with 5 lips labyrinth sealing
system + steel protection cover
