Going to look at NH running Gear Friday...

Hey Guys, Going to look at some NH running gear on Friday. The craigslist seller wants $600 for the gear and claims its 10 Ton. Besides checking the obvious, (cracks, welders bends). Anything else on these running gears problematic? The seller says its 10 ton, but if there aren't any decals stating it, is there any way being able to tell? I am hoping to make this into a 20' deck to be used with my accumulator/grapple. Thanks
