I don't concur about the World Lawn mower, a 5 x 10 trailer or a cheap blower, but that is one way to go.
But the bottom line is that you can "go as you grow". Just don't expect to be putting much if anything in your pocket at first. I started out with a $10k investment in my business and didn't take anything out of it for the first year. There are lots of little things that eat through cash too.
