ABSTRACT:
A cable burying machine having three plow blades which are mounted on a rotating disk. The disk is restrained from movement in normal operation, but if the active plow blade encounters an obstacle which imposes more than a preset force on the blade, the disk will automatically rotate, preventing damage to the blade, and bringing the next blade into position. A remotely operable tripping mechanism can be used to reduce the amount of resistance to rotation which was preset, thereby allowing an operator on a surface vessel to command a plow rotation to remove debris from the active plow blade.
