The Charles Machine Works, manufacturer of Ditch Witch, introduces the 420sx vibratory plow. The unit features a dual-speed attachment drive. With two speeds, the operator can quickly adapt to changing ground conditions, whether plowing or trenching. The 420sx is designed to closely follow the contour of the ground, which helps the attachment maintain a constant plowing depth on uneven terrain. Besides a standard vibratory plow, the 420sx can also run a Roto Witch boring attachment and a trencher.
