This invention relates to a cultivation device intended for the cultivation of soil and pulled by a vehicle, the device comprising a frame (6) with a drawbar (4) attached to the frame, or which frame (6) is intended to be coupled to a drawbar (4); an attachment shaft (8) for mouldboards (10', 10'), the shaft extending substantially in the direction of the longitudinal axis of the frame (6); and mouldboards (10', 10'); and a drawbar (4) which is coupled or can be coupled substantially centrally to the frame (6) so that the angle, between the longitudinal axis of the frame (6 ,) being substantially transversal regarding the driving direction during cultivation and the drawbar (4) being substantially in parallel with the driving direction, is arranged to be adjustable. A cultivation device according to the invention is characterised in that there are two types of mouldboards (10', 10'); first mouldboards (10') which during cultivation turn the soil to the right in relation to the driving direction; and second mouldboards (10') which during cultivation turn the soil to the left in relation to the driving direction; that the mouldboards (10', 10') are fastened to the mouldboard attachment shaft (8) so that the first mouldboards (10') are substantially parallel in relation to each other, the second mouldboards (10') are substantially parallel in relation to each other, and the first mouldboards (10') are directed in a substantially different direction in relation to the second mouldboards (10'); and that the mouldboard (10', 10') attachment shaft (8) is arranged to be rotated around its longitudinal axis so that there are at least two attachment shaft (8) positions to be used in the cultivation; a first position where the first mouldboards (10') are arranged during cultivation to turn the soil to the right in relation to the driving direction; and a second position where the second mouldboards (10') are arranged during cultivation to turn the soil to the left in relation to the driving direction.
