A trencher includes a drive mechanism, a detachable digging box, and a digging support member. The detachable digging box receives power from an intermediate drive member transferring power from the drive mechanism to a trenching chain coupled to the detachable digging box. The drive mechanism and the detachable digging box are coupled to the intermediate drive member. The digging box support member includes a first end and a second end. The digging box support member is pivotably coupled to the detachable digging box at the first end of the digging box support member via a detachable coupler and pivotably coupled to a frame of the trencher at the second end of the digging box support member. The detachable digging box is detachable from the digging box support member via the detachable coupler without decoupling the intermediate drive member from the trencher.
