ABSTRACT:
A trenching apparatus is provided having a base support which mounts a boom structure carrying a digger arm operative to form a trench alongside the base support along a trenching line. The base support includes a pair of longitudinally spaced sleeve members connected to a first track assembly which slidably receive a pair of longitudinally spaced slider members connected to a second, wider track assembly. An adjustment mechanism is provided to move the slider members, and, in turn, the second track assembly, laterally within the sleeve members between a retracted, transport position in which the first and second track assemblies are spaced relatively close to one another and readily fit upon a trailer commonly used to transport heavy equipment along roads and highways, and an extended, operating position in which the first and second track assemblies are relatively widely spaced from one another to provide the apparatus with acceptable stability during a trenching operation.
