Abstract: A clamp for hydraulic hoses having a base member formed with one or more substantially half-circle cutouts and a clamp member pivotally connected to said base member and formed with corresponding substantially half-circle cutouts, such clamp member being pivotable from an open position to a closed or clamping position wherein the half-circle cutouts form full-circle passageways for individually retaining a hydraulic hose. A locking pin retains the clamp in its clamping position by insertion thereof in aligned through openings, there being a loop member or ring on the end of the locking pin to at least partially encircle the base and clamp members to retain the pin in its locked position.

Abstract: Ground-moving equipment comprising an arcuate main blade to be fixed to suitable motive power means such as a bulldozer or the like, and an elongated auxiliary blade hingedly connected to said main blade and operable for forming or cleaning a slope which extends upwardly or downwardly from the position of the bulldozer. More specifically, it comprises a pivotal connection between the auxiliary and main blades, and a hydraulic actuator also connected between such blades and operable to enable the relative positions of such blades to be changed from a remote location.

Abstract: A ground-shaping system attachable to and usable with a back-hoe bucket to shape the upper portions of a ditch to be formed, and to provide flexibility in affording many alternatives. It comprises two, three or more ground-cutting members and clamp means for securing said members relative to the side wall of a back-hoe bucket, there being a back plate for cooperating with the bucket side wall to remove the ground cut by the cutting members.

Abstract: A drain ditch digging attachment which is used with a back-hoe and which is provided with a generally V-shaped bucket for removing ground to form an elongated drainage ditch down or along a slope. The attachment has a long transverse reinforcing bar across the bucket and extending beyond the opposite ends thereof, such extensions having ground cutting and moving members such that the attachment not only digs the ditch but also forms the edges or sides of the ditch in one single pass of the attachment without the need for additional manual labor.
