Beg to differ on the lawn mower issue. When speed is of the essence, as you will find out one day when you have children running around your feet, a lawn mower does a stirling job. I have done it every year, with the same mower, and it is still going strong. Also, the leaves get mixed up with some grass cuttings which warm up nicely and help the breaking down process along.

If it's not entirely rotted down next spring I don't worry
