Trolleys are the first tools to be used in a plowed field in spring, right after the snow melts. They are designed to create conditions for quick drying and heating of the soil, while preserving water in the deeper layers of the soil.. The work of the dragline consists in cutting the ridges of the furrows and leveling the recesses between them. These effects are best achieved when the trawl is led diagonally in relation to the direction of the plowing. The simplest harrow is usually made of several steel angles or flat bars, the so-called. belek, parallel to each other. These angles are hinged to each other, so that they can adapt to the unevenness of the field surface.
The first angle cuts the ridges of the furrows, the second and the next ones level and partially loosen the surface of the roll.
