I've got a 100 X 200 lot. 22 Oak trees. I know about leaves, ok? I have had every tool known by man; blowers, vacs, mulchers, back pacs ad nauseum. None of them are ideal.
I have a Husquevarna riding mower, YTH 150 Automatic. I purchased the Cyclone Rake. It hooks up behind the Husky. Google Cyclone Rake.com for info. This machine is the berries. You sit on your behind and it picks up everything. It has a hose attachment so you can suck up leaves in difficult places around the house or in flower beds. When you are finished, it collapses down, the engine comes off on its own wheeled carriage, store the hoses etc. Takes up almost 0 space when taken down in a matter of minutes.
Trust me, this machine I should have found 20 years ago. Worth every penny and then some.
