I am looking at buying a IH 500C. Shows 1300 hours on it. Comes with a 6 way blade and rippers. Starts right up but has a small water leak along the casing below the head (could be welded shut or JB pretty easily, leak is pretty small). The guy is asking $4500 for it and says he negotiable. I can't find any ads or prices on this dozer. Did some research and sounds like the torque converters are a main problem with them. Curious is anyone can give me a educated ball park figure of what it would be worth. Do not want to get ripped off and it seems to be a decent asking price from what I can tell. Don't plan on doing heavy work with it, minor grading, removing small 10 acres orchard type stuff. Any help or advice would be great!
