This model gathers stones in rows to reduce the stone collection time for the stone picker machine, clearing stones in a speedier way. Works with stones less than an inch in size to 23 in. Depth can be controlled from the tractor. The windrower is equipped with a drive system that allows a regular speed of the rotor. Moreover, the machine has a double function, that is: further to place stones in rows, it moves and levels the ground, it breaks the sods and, eliminating the grass, it leaves the soil itself ready for seeding. By positioning the working unit centrally, by means of a hydraulic cylinder, the specific hoeing work can be carried out, the performances of which are similar to those obtained with milling machines and harrows.
