I have a
B7100 manual scanned into word perfect. If you don't have that, let me know what format you have. I can convert it into almost any format. Think it'll work. The reason I asked the year, is that the early models didn't have hydrostatic. So, if your's is hydro, then this owners manual won't help you. It only covers 5100, 6100 and 7100 2 and 4 wheel drive. Let me know. I do have a service manual that isn't scanned in yet, but it does cover both gear and hydro models.
Also, the file is pretty big, 80 meg, so I'd have to break it up and zip it. Let me know if that would be a problem.
Keep the greasy side down.
