<p>The tow bar (1) is arranged with clearance between two plates (2) fitted to the plough frame, and can pivot laterally around the coupling bolt (8). When the plough is raised for transport or replacement, the bar can be locked so that the plough no longer is pivotable around the coupling bolt. The plates (2) for the coupling bolt (8) have rectangular holes (19) extending transversally in the towing bar longitudinal direction. The towing bar has two contact components (11,14) fixed to the plough frame, which are spaced apart in the bar longitudinal direction, being on one side of it. The coupling bolt is located on the opposite side of the bar to them.</p> |
