Abstract

Additional road-grader unit for a vehicle, in particular for a tractor excavator 1 or similar. The invention is characterized in that the unit includes a frame which supports a working part 22, whereby the said working part consists, for example, of a road-grader blade and the frame has been detachably coupled to the vehicle, partly by devices 2, 6 and 32 which operate the frame, and partly by the frame itself and devices 3, 4, 16 and 17 which control the blade level. The said level-control device is formed partly of extensible support arms 16 and 17 or of hydraulic cylinders, and partly of support legs 3 and 4 on the tractor excavator. With the additional help of the said level-control device, adjustment of the blade in relation to the ground surface can be fine- tuned. At the same time, the unit can be operated by the control devices 2, 6 and 32 on the vehicle. <IMAGE>
