It is a conceptually simple machine whose rotation is given by the insertion of specific inserts in the ground, which allow it to self-adjust the rotation speed according to the progress of the tractor.
In case the machine is applied behind the inter-row disc, it performs a completion work, levelling the ground and removing the earth in the immediate vicinity of the plant. The star does not damage the plant as the rotation is not supported by a hydraulic motor but is simply carried out by contact with the ground.
The machine is easily adapted to different shapes of the ground by means of a piston that regulates its inclination.
In this way a finished work is obtained, which allows the ground to be broken and levelled in the row.
