Remove soil from deposited plants and weeds

To control weeds and unwilted cover crops effectively, a layer of plant and root residues needs to be deposited on the surface of the soil. The optional tine harrow plays a vital role here. In addition to depositing the organic matter on the surface, it also removes soil adhering to the roots. All set with optimum conditions for sustainable weed control.

Rear harrow

The optional rear harrow with a tine diameter of 12 mm can be mounted behind the rear roller to leave a finely crumbled surface that provides the best germination conditions for seeds and volunteers. At the same time, the rear harrow combs out roots and plant residues pressed into the soil by the rear roller and distributes them across the surface to dry out. In addition, the structure left behind by the rollers is levelled again and only crumbled on the surface to prevent capillary action right up to the surface so that the water remains in the soil.

Heavy-duty tine harrow

When the PLANO is deployed without a rear roller, a heavy-duty tine harrow is available as an option to be installed in its place. The harrow is equipped with three rows of 12 mm thick tines. These ensure the necessary distribution of organic matter as well as levelling and crumbling the soil behind the tillage tools.

The heavy-duty tine harrow can be adjusted hydraulically and folded completely away from the working area. The angle of soil entry and working intensity of each row in relation to the other rows can be adjusted mechanically. The height of the harrow is adjusted automatically by linkage rods to match the setting of the depth wheels.

Despite the close tine spacing of 12 cm, the three-row configuration with an interval of 45 cm provides good clearance for high volumes of organic matter.
