Needing operator/user manual for 1989 Roper/Rally

[Rallyrider]

I have a 1989 Roper/Rally 18 hp riding lawn mower. Mod#GT2500BR with SN# 0379501396. I seem to have "misplaced" the operator/user manual for it, and would like to know where I can get another one. I have tried the "google" route, but not being very savvy, with computer use, I haven't been able to locate one to buy or download a PDF file for a manual for this mower. If anyone can give me a link directly to a PDF of it, or know a sure link of where to call or order a manual for it, I would very appreciative if you could help me out. When I do get a link, it's usually one that takes me to several other links, which none of them seem to have anything to do with what I'm looking for. Thanks in advance to all, for any help you might send my way via this forum.
