(1) covington SD79A shaker pan. This vibrating pan is for the covington side dressers, not the planter. If you are unsure of which shaker pan you need you can look to see if your pan has a divider in the middle of the pan(as in the pictures). If it has the divider it is for a side dresser/ no divider is for the planter.
