Adjustments and operations
Cutting depth adjustment - disc gangs opening
The cutting depth can be adjusted in two ways:
1) By adjusting the opening angle (lock) of the disc gangs.
2) By activating the hydraulic cylinder so the tires can work as depth stops.
We recommend controlling the depth using the disc gang opening and to use
the tires only where the disk harrow penetrates excessively.
Increase the opening angle between the gangs to work over soils with greater difficult
to penetrate the disc blades. In light and loose soils, the opening angle must be smaller.
This adjustment is done by changing the disc gang fixation on the frames.
To start the harrowing, we recommend an average disc gang opening.
If a greater penetration is required, increase the opening angle of the
rear disc gang.
The front gang usually operates with a greater opening compared to
the rear one.
The harrowed ground is always on the left hand side of the operator
(harrow closed side).
Try to make a good finish between passes. Avoid the formation of furrows
or untilled strips.
