Model XL3300 Track Star excavator is engineered for mobility on and off paved surfaces as well as on rails. The machine quickly switches between a wide range of attachments, including mowers, buckets, grading blade, 4-foot-extension, and a grapple that can remove and replace rails and ties. Because the Gradall boom telescopes into position, the unit works efficiently in low-overhead conditions. It does not require working mode selection like conventional models.
