A centrifugal distributer is provided with means on the frame of the implement for indicating the angular setting of the sector through which material will be ejected from the spreading member. As shown the means comprises a plate 28 which is moved by contact with the material. This may be replaced by a funnel leading to a measuring cylinder or a pressure plate may be provided which operates a switch on impact of material on the plate. The devices are situated outside the spreading arc when it is in its correct position so that when material contacts the devices it means that the spreading arc is incorrectly position. |
