5.2.5 Automatic
overload
safety device for the tines
The automatic overload safety device for the tines protects the frame and the tines
from overload. The spring of the overload safety device has been preset. This set-
ting must not be changed.
5.2.6 Hollow
discs
The hollow discs protected by shear bolts are serrated and level the soil behind
the tines. They level the ridges which are thrown up by the tines on the back row.
The hollow discs are also available with an automatic overload safety device.
5.2.7 Edge
discs
The depth and pitch angle of the edge discs, protected by shear bolts, can be ad-
justed. They should retrieve the soil which has been thrown out. The edge discs
are also available with an automatic overload safety device.
5.2.8 Rollers
The rollers ensure reconsolidation and additional crumbling of the soil. During op-
eration on the land they bear the weight of the implement if the implement has
been lowered for work and they ensure exact depth guiding. The weight of the
rollers can also support the feed behaviour of the implement. The implement can
be fitted with different roller types.
5.2.9 Hydraulic transportation lock
In the folded in transportation position the hydraulic transportation lock prevents
the side parts of the device from unintentionally folding out.
5.2.10 Drawbar
The drawbar has optionally the category Cat. 3, Cat. 3N or Cat. 4N.
The drawbar mounting position influences the implement's intake behaviour, lifting
height and the roller pressure load as well as the tractor slip when working.
5.2.11 Feeler wheels
Feeler wheels are used to improve the depth guide.
