I got most of my mower fleet off the leafy streets of Melbourne's South Eastern suburbs, East Malvern, Armadale, Toorak, Caulfield and Kew on Hard Waste days, was able to pick and choose, if it looked complete and had a bit of compression when pulling on the starter it was mine.
Maybe find out when there's a HW day in those areas and take a drive Norm.
Since I left Melbin for the bush in 2016 my reputation as a scrounger and fixer has led to people giving me more stuff, I seldom say no.
Works both ways, I have given away some perfectly functional fixed-up mowers, chainsaws, brushcutters to people down on their luck,and oddly enough they have then given me devices they have found which they have no use for.
I gave one fellow a good Victa Quantum mower. He has since given me around a dozen thingies which needed TLC and are now sitting here ready to be used, or given away.
For me it's not a business, just my penchant for keeping things out of landfill if possible.
