Ridging ploughs with attachment for ridge forming Noctu are designed for ridge forming on the potato plantation and vegetables planted in ridges. They can be used alone or with an attachment that profiles and compacts the ridges. Ridging with attachment can only take place till the potato sprouting, because later the elements levelling the ridge can damage the plant. On the first beam of the frame is fixed legs with spring teeth used for loosening the soil between rows of potatoes. On the second beam coulter and bodies covering the rows of potatoes. On the back, on the connection arms there is an attachment that forms the final shape of the ridge and limits the countersinking of the teeth. The machine with elements arranged in three sections forms 2 rows (2-row version), and in five sections 4 rows (4-row version). The width of cultivated rows can be adjusted in the range of 62,5 cm to 75 cm.
