For mobility on and off paved surfaces, as well as on rails, the Model XL 3300 Track Star hydraulic excavator from Gradall, New Philadelphia, Ohio, will get the job done. The Model XL 3300 (Circle 901) can quickly switch between a wide range of attachments that can include a mower to clear away vegetation or various buckets to clean up landslides and maintain trackside slopes and grades. Because the Gradall boom telescopes into position, the Model XL 3300 requires only minimal headroom, allowing it to work efficiently under bridges, signage and in tunnels. A 148-hp turbo-charged John Deere engine powers both the upper structure and the four-wheel-drive undercarriage, and both axles are equipped with internal wet-disc-type service and parking brakes.
