9000 Hrs on a 1983 6620SH. May not be a lot for the engine but for the rest of the machine....

It was one of two machines a couple brothers had from new. They claim they never touched the engine.  They went through them every year replaced what was needed themselves. Most of their ground was fairly rough as well, running 6 row corn heads and 20ft platforms. Traded one a few years ago for a 9550 SH. I was never up close to one but other than having faded paint they didn't look to bad.
