NZG Caterpillar D9N fitted with metal tracks, idlers and sprockets. Metal grab rails added and detailed hydraulic hoses. One of my whitemetal angleblades c/w rubber hoses added, new metal exhaust stack. Undercarriage cleaned up and repainted with a 3D printed tow hitch added. EDIT-I added a fitting to connect the rubber hoses on any of my towed scrapers to the D9. Extra photos showing the models , please note the scraper shown in the photos is not included with the listing! Thank you. Edit-forgot to mention that proper brass grab rails have been added! The tractor would be suitable for one of my towed scrapers listed! Box for the model as well
