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 mould-boards ( 10', 10 ''), the shaft extending substantially in the direction of the longitudinal axis of the frame ( 6 ); and mould-boards ( 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.
