Hi Adam, welcome to Outdoorking.

We do not have any information on a Victa 8-30 in our manuals section. You are probably aware that Victa did not manufacture ride-ons, they imported them from the US and labelled them Victa. The first step in your project would be to find out who manufactured the 8-30 and what was the correct model name or number. Then we could try to find some information. I suggest that you begin by sending a Private Message (see My Stuff at the top of the page) to Bruce, the Outdoorking site owner. Bruce is a very experienced mower dealer, and he can probably supply the information you need on model number. He may even be able to find and upload some technical information.
