Just inherited my first Polaris Ranger. Its a 2013 Polaris Ranger Crew 900 Diesel. Has 800 hours on it, was used at a ranch in Austin for hauling stuff around and getting to the deer blind and back. I'm not sure when the last time it was serviced, or much about any of it. I figure the first thing I'm going to do is have everything serviced on it such as oil, filters, transmission fluid, and all that. How often should I service the engine, what things do I need to watch out for, and are there any helpful hints from anyone out there for a new owner of one of these diesels?
