<p>The invention relates to a hauled two-row potato planting machine, meant for planting potato tubercles on two rows simultaneously with the administration of mineral fertilizers. According to the invention, the machine comprises a unique frame (A) having some supporting leading wheels (2 and 3), having between them a distance adjustable in three steps, a monoblock tank (C), penetrated by a vertical wall (15), which confines two compartments (g and f), one for potatoes and the other for the fertilizers, having the possibility of increasing the capacity of the potato tank (g) by removing the vertical wall, said machine allowing the potato planting at three various distances between the rows (d1, d2 and d3) arranged in arithmetic progression with the ratio r, two pairs of welding flanges (7, 8, and 9, 10) being located symetrically relatively to some axes (b and c) at the distances r/4, wherein the distances r/4 to some symmetry axes (d and e) are fixed in various combinations.</p> |
