I just bought an ancient Bobcat Ransomes 36" w/b with a 12hp Briggs and Stratton Engine. The thing looks like crap but seems to run pretty solid for 400 bucks. I want to learn as much as I can about maintaining it before the season starts. I don't wanna be mowing somebody's yard and then a belt snaps and I don't know how to fix it. It also has an electric start with no battery or charging system to support a battery so I have to find a pull starter for it and install it. I ran a search online and couldn't find a B&S Dealer near me - can I go somewhere else. Where can I find info on how to work on this thing. Besides the belts, I need to know what to lube, how to remove and replace the blades for sharpening, etc... Any ideas/suggestions?
