FIELD: agriculture.SUBSTANCE: invention relates to agricultural engineering. The plough comprises a frame on which at least one plough beam is mounted, using an appropriate casing. The plough beam comprises a rotary axis at its front end, resting on the support. The support is formed in the casing. The plough beam is held on the casing by means of traction, on which an actuating cylinder operates with the traction force. The plough comprises a device for intentional lifting of the plough beam due to its rotation about an axis substantially corresponding to the said rotary axis.EFFECT: constructive implementation enables to change the plough width according to the properties of the treated soil.11 cl, 5 dwg |
