Looking at a JD 790 excavator, is there anything to look out for other than the obvious things like oil leaks bad pins and bushings or undercarriage. Went to the JD part's page and found out it was made by Hitachi. I've ran a John Deere 892Elc and 992 Elc, which were alot newer, and bigger, just haven't messed with the earlier models before and would like some insight from someone if this model is one to stay away from.
