1. An excavating machine including a main frame mounted for pivotal movement to a chassis, a digging implement arranged along a longitudinal axis of the main frame and is removably mounted to said main frame in a manner for effecting lateral movement therebetween so that the digging implement is arranged for excavating longitudinally of the machine at a location selected within a range of lateral movement that at least includes a generous portion of the width of the machine;

  • upper and lower guide means attached in spaced relationship to said main frame, said guide means extend perpendicular respective to the longitudinal axis of the machine and are arranged in parallel relationship respective to one another;

    a support structure has upper and lower journal means by which said support structure is supported from said main frame and by which said support structure is connected for low friction slidable lateral movement respective to said upper and lower guide means;

    mount means pivotally supported to said support structure;

    said digging implement is supported by mount means which in turn are supported by said support structure;

    whereby;

    said upper and lower journal means moves said digging implement, mount means, and support structure along said guide means to selectively position said digging implement laterally of the chassis.
