ABSTRACT:
An excavating machine is provided having an adjustable grooving device for forming a groove in the bottom of a trench. The excavating machine has a power unit, a supporting frame assembly operably attached to the power unit, an earth cutting device to form a trench behind the excavating machine, and a shoe assembly operably attached to the supporting frame assembly to prevent a cave-in of the sidewalls of the trench. The adjustable grooving device is attached to the bottom of and extends below the shoe assembly and is comprised by two arcuate groove plates which pivot relative to one another to form an arc of varying radius. A hand crank is operably attached to a linear actuator for pivoting the arcuate groove plates relative to one another to adjust the radius of the groove to be formed.
