I'm looking at a used Oliver with a loader/backhoe but i'm not sure of the year and model.  It maybe an industrial model but i'm not sure.  Its got lots of plate steel, fenders and sheetmetal are all heavy.  The backhoe seat is up high behind the front driving seat.  It looks really heavy duty. Any info will be welcome or give me a direction for pics???  I'm not sure what these are worth?  They say it runs and all the hydraulics work.  Its yellow and has square metal fenders over the rear tires, the owner says its an Oliver.  This machine looks as rugged as a dynahoe.  It seems to have two trannies(hi/low).  I think its also a deisel engine too.  I'm sorry i'm new to olivers i mainly collect and use international harvester stuff but i'd like to branch out to other equipment too now, much bigger than my cubs and cub cadets. I looked at the oliver pics and the model 550 seems to be close to what i'm looking at to buy.  Are there parts still available for it too? 
                                                     Thank's Bill

I can't do pics my puter is running but not at its full potential.  Its outdated and i need a new puter soon.
