I have a 2003 B-7800 and got a parts manual from Ronnie at Tractorsmart.com. He sent me a link and it was in PDF format. I also got the parts manual for the loader (LA-402) and the 60" mid mount mower (can't remember number). I have all of them in PDF format that can be e-mailed. If you want the files that I have send me a pm with your e-mail address. You can print them out or look at them on the computer.
I didn't bother with the service manual as I've asked questions on here and never had a need for one. /forums/images/graemlins/grin.gif
