The Plate that partially covers the left or right exit point of the chute prevents any snow entering the chute and impeller drum while the impeller paddle is rotating and throwing snow out through the chute and spout of the snow caster.
EDIT: It should read "the plate barrier covering a portion of the impeller drum opening prevents snow from escaping while the impeller is turning and casting the snow out of the chute and spout"
Whoopsie on my part
