We live in an area that tends to get a lot of wet snow - with temps that hover just above or below freezing for much of the winter. One of my relatively consistent problems with my BX2750 snowblower (front attachment on a BX24) is that a thin layer of ice tends to collect between the auger and the back of the chute - or in some cases right at the edge of the auger blade in the chute. If I stop for a bit and forget to check and clear this, it often freezes and ... there goes another shear pin. Annoying, but not a game-breaker. Anyone have a trick to stop this from happening?
