Abstract
An agricultural device is couplable to a tractor vehicle with carrier arms. The agricultural device comprises a carrier frame with a set of wheels and a coupling device for coupling the agricultural implement to a tractor vehicle. The agricultural device further comprises a coupling frame having at least one coupling point for coupling of the coupling frame to both carrier arms of the tractor vehicle. The coupling frame is connected to the carrier frame so as to be rigid in rotation in the vertical plane, wherein at least one coupling point of the coupling frame is positioned on or above the center line of the carrier frame. Owing to the fact that the carrier arms extend horizontally or upwards, the carrier arms will not or will hardly get out of position as a result of the travelling of the vehicle.
