Abstract
The slide 4 of a centrifugal distributer, which controls the flow of fertilizer from a hopper 1, is adjusted by means of a lever 5 which is loaded by means of a spring 11 so as to give it a snap action in the manner of a toggle. In one position, to close the slide, the lever 5 abuts against a stop 10 and in the other position the lever 5 abuts against a stop 9 which may be placed in any one of holes 8 to vary the open position of the slide.
