This is a pretty good example of what to look for, usually when this crack shows it's ugly head it has already been welded by the time I see it. This is a 2000 or 2001 Bobcat 763. A very common rental machine with a good history, radial lift arms but with the longer wheel base. I have seen this area crack in the past but not as common across the arms as it did in this case. Watch out for a step pad decal placement over top of the cracked area.
