In this video Ted from Everything Attachments shows how to use a Bradco 625 Trencher. This skid steer hydraulic driven trencher attachment is digging a 6 inch wide hole that is approximately 18 to 24 inches deep. This trencher is shown with standard cut tooth and can be ordered with shark or solid carbib bullet teeth. The hinged cast crumber assembly is an important part of the trencher, keeping the dirt back to the teeth so that the auger can pull the dirt out of the hole. br Order a Bradco Trencher attachment for your skid steer at .
