Adjustments and operations
IMPORTANT
•
To start the harrowing, we recommend using an average disc gang
opening. Adjust then, if necessary.
•
The harrowed soil is always on the left side of the operator (closed
side of the harrow).
•
Try to make a good finish between passes. Avoid the formation of
furrows or untilled strips.
•
The tractor and harrow drawbar should be as aligned as possible
to the work direction.
The cutting depth is adjusted by the
disc gangs opening.
Increase the opening (A) between the
gangs to work in soils with greater difficult
to penetrate the disc blades. In light and
loose soils it is appropriate to work with a
smaller opening angle.
To open or close the harrow, activate
the adjusting bar by pulling the rope and
move the harrow forward or backward to
the desired setting.
