Rotary harrows, called Moslavka, are intended for family farms especially for finishing soil tillage before sowing of arable and vegetable crops, with the possibility of application in fruit growing. They are manufactured in different widths, depending on the tractor power, and are connected to tractors having power from 30 to 110 HP, depending on the working width. The depth of the treated layer is up to 28 cm. Rotary harrows come with one of two possible levelling rollers – packer or tubular. Rotary harrow operation is very simple and efficient because it replaces all other operations, such as harrowing, dredging, ploughing, etc. in one pass across the soil.
