I looking at buying what I think is a 2006 Monatana 4340C. There are no decals for the model #'s but the owner says its a 4340C. The chassis model# on the s/n plate shows N55D. I can't find anywhere on the tractor that says 4340c. It looks indentical to the 4340c on the website. What would this model sell for new and what would it be worth used with 700hrs, a loader, and 4wd. Good condition, no implements.
