G'day Helweg,
welcome, what model Victa is it? Can we see piccies?
If they're are tonnes of mowers being dumped, they must be getting vacuumed up by many more eager scroungers then as I rarely come across any.
One time recently I came across two Victas in average condition and within a minute a car pulled up and the driver was asking me if I was taking them -as I was wheeling one to my car! He said ok in a resigned voice.
Another time I disposed of the decrepit remains of a Victa with missing wheels and stripped engine in a quiet street with no though traffic and within a couple of minutes a Commodore station wagon pulled up with the passenger quickly loaded it in. I couldn't believe it.
