If you do not know how to evaluate the tractor, most important the undercarriage, then you will be better off taking someone else with you to look it over. Even if you have to pay for someone to come out. Most likely be far cheaper to pay someone to than it would be to buy something only to find that it needs new pins and bushings or chains.

Hi rotorbob,
a list of things to start with are:
- check wear on the undercarriage: main points are pins and bushes, sprocket, idlers and rollers. For this, there is a tool (track gauge) that can be used to determine the amount of wear. There's also track frame alignment which can be checked if the machine can be moved
- does the engine run, does the machine move in all gears and steer as expected, and all controls/components work as expected including controls like the clutch/brakes and also the loader components
- leaks and/or broken items, worn/loose items, strange sounds/knocks etc.
As oldtanker wrote, a second pair of (experienced) eyes is always good, particularly if that pair of eyes can check things while you run the machine.
