Cat 247B3 SharpGrade Extraks and SharpGrade laser grader 

Cat 247B3 fitted with SharpGrade Compact 1.8DGR laser grader pushing out a pile of sand.
SharpGrade is working in full automatic mode and resets as soon as it receives a signal again.
Machine is fitted with Extrak sprocket extensions. Note how the tracks lay flat on the sprocket and do not flex. The Extraks drive on the outer set of lugs, eliminating drive lug failure and reducing track split. This allows the operator to achieve maximum life from their tracks, instead of discarding them through failure.
These units have done 3000 hours with no maintenance to the sprockets. The original tracks have only recently been replaced.
ExTraks fit Terex PT50,PT60, ASV RT60,RT75 Cat 257B,B3,D
