I need an owners manuel for a wizard tiller Model #
GIS 6990A27 can ay one HELP.
It doesn't appear there are any manuals online-
It's a Gilson tiller.
Don't have that one, But most of the gear drive front tine tillers of the era used the same belt arrangement shown in Bills post. The reverse belt was twisted ( crossed) to change direction. Standard Briggs engines. If the lower unit is your problem, it will be difficult to get parts.
