I'm looking for recommendations for a service manual for my b6000. I have the owners manual with a complete parts listing according to group ie. mission group, took me a while before I figured that it was the transmission that was being referenced. I have what sounds like some kind of scraping noise in the front end and it does not seem to matter if the tractor is in 4wd or 2wd. I want to look into it before the snow comes but would like to have some kind of manual before I start taking things apart. Thanks for the help.
