Here's my cheaper, lower tech method for getting leaves. It involves a little sweat, but is not back-breaking work.
Each fall my wife and I rake the leaves into sizeable piles, (gloves are a must with rake handles by the way, unless you like blisters)
then we get a king sized blanket or sheet, lay it on the ground, rake the leaf pile onto it, pull the corners together, dump it in the pickup, smash it down by walking on it, repeat. We usually can fill up a full-sized pickup bed and a 7'x4' trailer in one hour or less. Then we back up to the garden and dump it right on top. If we need more leaves, we go down to the forest service road, and get the leaves from the side ditches using the same approach. It is amazing how quickly large quantities of leaves can be gathered in this fashion.
I have my power mowers, riding mowers and such, and I love using them, and I'm still excitedly looking for my first tractor, but sometimes I think we all use these things simply for the sake of using them. In many cases, simple labor is faster, more efficient, cheaper, and in my opinion, more satisfying.
