Oliver 550 Weak Points

I'm going to take a look at a 550 diesel that's for sale tomorrow. I'm not real familiar with Olivers. Any common weak points on this model I should watch out for? Thanks for the help.
 
Does it run? 1958 is the first year for the 550. They use a 144 cubic inch engine. In 1959 the displacement was increased to 155 cubic inches. So get a serial number. Many owners never adjusted the PTO clutch like it should have been. See how much effort it takes to snap it over-center. How does it start? In late 1960 the fuel system was changed from American Bosch to a Roosa Master system. The Roosa Master is easier to get parts for. Does it have power steering? How about a drawbar?
