Turn tractor

In the boom period of observation "Circles" around the world, the witnesses, yielding to the excitement, took them for a lot of ordinary things, like the antics of a wind, Pets on a leash or mycelium. All these reasons give a very simple structure and is relevant to the present. In this article we will examine another reason for the appearance of drawings in the margins of this category - the turning of the tractor.

Phenomenon it was adopted relatively rarely, mostly by accident and out of ignorance, witnesses who view the picture at a certain angle, see the pattern of the area or photos.

Let us examine the principle of formation of the pattern and its possible forms.

In the processing field of agricultural machinery moves along the treated area. Its edge technology is needed to unfold. Reversals are often carried out outside the territory of the field, but this is not always possible due to landscape. If idle cannot be performed outside the treated field, with one or two stand out sides of the headland, designed to turn equipment. The width of these bands depends on the radius of the rotation unit and a rotation.

The greatest width of the headland is obtained by the full loop rotation, the smallest – in the corners of the semicircle and the return journey [2]. In cases where the area may be treated in two ways, headland isolated from all four sides of the plot. [1]

Knowing basic shapes, locations and the principle of formation of the pattern left by agricultural machinery in the turn, it's easy to distinguish it from the "circles" that have emerged for other reasons.
