Abstract
An adjustment that includes preferably a pair of spaced, resiliently supported, holders for supporting a cut-off brush against the perforated inner periphery of an air charged, seed containing rotatable drum to remove excess seeds therefrom. The holders rotatably support a pair of brackets having rotatably mounted gauge rollers that engage the inner periphery of the drum. One of the brackets is rotatably adjustable relative to one of the holders to vary the position of the holders and thus the brush in relation to the drum interior for different size seeds.
