A double-deck plough comprises plough bodies of a plough of the upper deck and the lower one comprised by a ploughshare, a mould-board and a stilt. The plough-body of the plough of the upper deck is provided by a horizontal plate and a vertical curvilinear dashboard, mounted between the ploughshare and the moulboard, fixed on the stilt by means of a spring-loaded bracket on the side of a heel of the ploughshare. In doing so, forming curvilinear dashboards are parallel to forming mouldboards. |
