Hmmm, showed up as a 1995 or 1996 model when I tried, but wouldn't open when I tried the serial number range. Did you try any other model numbers? I tried just opening a random model number from the model list, and same thing, it wouldn't open the manual when I tried the serial range. I'll try on another day, and if it still doesn't work, I'll try emailing Toro.
I have contacted Toro and told them of the trouble that seems to occur in getting their manuals online. This was their response.

Toro has been very responsive in sending pdf of the manuals I have requested of them via email since they would not download from their site. If anyone else is trying to get an owner's manual, and cannot get it to download, try contacting their customer service via email.
For fairly modern mowers, you can often find the owner's manuals on the Home Depot website. Just search for your model, and scroll down to the bottom of the page until you see the link for the "Use and Care Manual" and click on it.
