Brushing machines remove the awns (stiff, slender, sometimes barbed stalks) when grass seeds are cleaned. Rotating brushes cut off the awns by scraping the seeds against the brushing machine’s wire mesh mantle screen. The improved brush cleaning combs keep the awns from clogging the rotating brushes.
