Adjustments and operations
Cutting depth - Disc gangs opening
The cutting depth can be basically adjusted in two ways:
1) Adjust the opening angle (lock) of the disc gangs.
2) Activate the hydraulic cylinder so the tires will work as depth limiters.
We recommend controlling the depth through the disc gangs opening and to
use the tires only where the disk harrow penetrates excessively.
To start the harrowing, we recommend using an average opening on
the disc gangs. If more penetration is needed, increase the opening
angle of the rear disc gang.
The front disc gang usually works with a smaller opening compared
to the rear disc gang.
The harrowed ground is always on the left hand side of the operator
(harrow closed side).
Try to make a good finish between the passes. Avoid the formation of
furrows or untilled bands.
IMPORTANT
NOTE
The opening angle should increase between the gangs to work over soils with greater
difficult to penetrate the disc blades. In light and loose soils, it is appropriate to work with
a smaller opening angle.
This adjustment is done by changing the fixation of the disc gang carriers on the frame.
