Working procedures
Modern cultivators are equipped with regulators of depth of loosening and motion speed. If on the site the firm earth, recommend to carry out at first loosening on small depth, and then to increase it. The main tool of cultivator are mills, at the majority of models they are executed in the form of several sections. Changing their quantity, select the necessary width of processing. If soil clay and heavy, quantity of sections it is necessary to reduce. Carefully to plow the soil, it is necessary to choose the fast rotational speed of mill and slow motion speed. Following cultivator, it is necessary to provide its uniform movement. It is possible to leave back cover of the device to be dragged on the ground, it will help to level the plowed field. After the end of all works, the cultivator is cleaned from the stuck earth by means of wood scraper. Then stream from hose wash out milling operating parts. For corrosion prevention it is necessary to wipe metal unpainted parts with oil-impregnated fabric.
