Abstract:
An agricultural appliance, in particular a field sprayer, that includes a boom construction (1) with a central portion (20) which may, by means of a suspension device, be mounted on a support construction (40), such as a tool bar on a tractor or the like, which is located posteriorly of the boom construction (1). The suspension device includes a pivot (150) that allows for turning of the boom construction (1) about the axis of the pivot which extends substantially perpendicularly to the boom construction (1) and horizontally. The agricultural appliance has a system of at least two rigid push/pull rods or struts (35-38), each of which connects a point on the boom construction (1) to a posteriorly located point on the posteriorly arranged support construction (40) by means of swivel joints (39), said push/pull rods (35-38) being so arranged that at least one rod is influenced by a pull simultaneously with at least one other rod being influenced by a pressure by turning of the boom construction (1) about the pivot axis (150).
