Craigslist ad from nearby, For 1500 is it a worth while deal? They say it's a 9F, I'm not familiar with Cat blades this old. http://eastidaho.craigslist.org/for/2001373503.html
I think that seems like a pretty good deal. Around here it's hard to get running antique tractors for that much
Anybody know where I could find information on a '9F' model?
Check ACMOC The nice folks over on the ACMOC BB might be able to give you a bit more info -- 9F1967TSP looks like the serial number. This fellow also has some basic info on old Cat motor graders... http://www.chriscomachinery.com/Graders.htm Good luck!
