Like magic, the vertical vibratory motion of the Power Potato Digger's digging pan fractures the soil ahead of itself, and enables BCS two-wheel tractors to eliminate the effort required to hand dig potatoes. The angle of the pan is adjustable, allowing for a maximum penetration of 6” below the level of the two support wheels, which are 14” in diameter and can straddle hill widths ranging from 20” to 30”. Located behind the 18”-wide pan is a set of horizontally vibrating bars through which the dirt and small stones fall. Plant residues are efficiently moved over the horizontal rods and deposited behind the unit. Operating with the handlebars offset, turning at the end of the row requires the addition of the Bumper Weight Kit. The attachment weight is 198 pounds and fits models 739 and up. The unit is manufactured by Italian company Spedo, which specializes in potato planting, ridging, and harvesting equipment.
