The service (Workshop) manual for your B6200 also covers B5200, B7200, and the HST versions of 6200 & 7200. As it is a manual for relatively popular tractors, it can usually be found on eBay over a period of several weeks/months. Last full Kubota shop manual I purchased off of eBay costs me around $45. Good luck in your pursuit...
