Abstract
A trailer device for an agricultural vehicle includes a frame part and a guide part longitudinally, displaceably mounted in the frame part. The guide part includes a coupling element provided on an end face. The frame part is pivoted by a lifting apparatus for raising and lowering the coupling element relative to a base frame for attaching to a load-bearing vehicle structure. The device includes at least one spring element arranged between the base frame and the frame part such that the spring element exerts a pretensioning force on the frame part for assisting the raising of the coupling element.
