Tool carrier for agricultural machines including a suspension device with a wheel (18) for contact with the ground and one or several tool holders (9), that jointly are suspended in parallel. The wheel is journalled in the tool holder or an extension thereof, that via two swing arms, (4,5) is journalled in a mounting device (2,3) for the suspension device so that a parallelogram suspension is achieved. In the travel direction the wheel is located behind the tool holder and the swing arms (4,5) extend in the work position rearwardly downwards from the mounting device. One or several springs are arranged between one of the swing arms and the mounting device effective to pull or push the tool holder forwards or downwards in the driving direction. The mounting device (2,3) is fastened to a crosswise relative to the direction of movement arranged beam (1), on which several mounting devices may be mounted. The beam is further turnable so that by a turning of the beam the inclination of the tool-holder may be changed in turn altering the relationship in height between wheel (18) and tool (13-15) for change of the working depth. |
