ABSTRACT:
A trenching apparatus comprises a boom assembly having a lower end mounted on a support base and an upper end connected to a boom mounting bracket which is joined by a coupler to a digger arm operative to form a trench alongside the support base following a trench line. Linear actuators are carried by the boom mounting bracket, the coupler and the digger arm to manipulate the digger arm about an X axis, a Y axis and a Z axis which are mutually perpendicular. Other linear actuators vertically raise and lower the boom assembly, and pivot it in an arc-shaped path relative to the support base, in the course of a trenching operation.
