<p>The present invention relates to a multi-furrow plough which is particularly suitable for working the surface soil and at the same time tilling the ground in order to facilitate the drainage, the oxygenation and the storing of humidity during the summer months. The main characteristic of the present plough is the ambiversatility and the variable angle displacement which permits on the one hand to carry out consecutive passages on the soil, both onwards and backwards, the direction of cutting of the tools being automatically varied, and on the other hand to automatically adjust both the angulation of the ploughshares and the distance among, the furrows. In general, the present plough comprises a fixed support (5) on an end of which a central part of an arm (6) is pivoted. The arm (6) is arranged horizontally and may be pivoted at least 90 DEG in both opposite directions. The aforesaid arm is moved in both directions by a piston (8), which may be hydraulic, pneumatic or the like. Moreover, the arm supports a series of ploughshares (15), the distance among them being adjustable. A tilling blade (20) is arranged under each ploughshare. <IMAGE></p> |
