Just aquired a 1990 M8580 4wd and it has no manuals. Which manuals should I get, and where should I look ? I know some about tractors but nothing about Kubotas. Thanks for any help.
You need the Owner's Manual --- check E-Bay; www.kubotabooks.com or the dealer.
You should have a Workshop Service Manual --- check E-Bay or order from a dealer
You need a Parts Manual --- free pdf download from www.tractorsmart.com or E-Bay for the printed manual. In my opinion, the printed manual is worth buying.
