Hi,
about 15 years ago my old mower died and I couldn't afford a good quality new one.
I knew one neighbour had a very old one, and another neighbour had an old victa that he used to cart off to mow the grass at his shack every so often.
I priced a new Greens professional mower (about $600 at the time) and put the idea of sharing the mower in thirds to the other neighbours.
Our sharing works well, but it may not do so for others.
I do the servicing every year, neighbour A pays for all the parts, and neighbour B stores the mower in his shed.
We each clean and refuel the mower after use.
Recently neighbour B sold his house, the real estate agent explained to a prospective purchaser that the mower in the shed went with the property, but as a one third share.
It was the mower sharing idea that clinched the house sale.
cheers
