This machine is developed next to the existing pneumatic precision sowing machines. The "3-punt" sowing machine is especially made for sowing seeds in the open field. The machine is pulled by a tractor, which also supplies the current and drives the sowing part on. The sowing part can be connected and disconnected separately by means of a display in the cabin of the tractor, as also the adjustment for the sowing distances. The parallelogram is adjustable over the whole width of the machine. Also is the depth adjustable with fine and coarse institution. 

The parallelogram has a special construction so that you always have (under any circumstances) an optimum depth of the seeds. By means of a menu-operated program will it be possible to make several different adjustments on a LCD-screen in the cabin of the tractor, like for example: quantity seeds per hectare or per square meter, separate adjustment per unit (rows on the outside, more or less seed) and it is possible to stop more sowing units at the same time, self-adjustable parallel run of the sowing units, and sowing distance, hectare, square meter and ground-speed are adjustable. The sowing distance in the row is adjustable per millimetre from 0,6 till 35 cm (depending on the type of sowing disc). The minimum distance between the rows is 11 cm. The machine is deliverable with single or double parallelograms.
