A bucket elevator adjustable guide system for efficiently dispensing grain from a bucket elevator with reduced grain dispersion. The bucket elevator adjustable guide system generally includes a head housing for a bucket elevator and a guide member attached to a lower portion of the head housing. The guide member is distally spaced from the head housing forming a lower vent and an upper vent between the exterior surface of the guide member and the head housing for air to pass through thereby preventing the accumulation of particulate material.
