May not be helpful if you can't tow it, but I use a zero turn mower towing a lawn sweeper. My driveway is lined with a Beech and 8 Sugar Maples and I have a 250+ year old Oak next to the house. Mowing over the leaves so they're confetti then sweeping them in the same pass was an absolute game-changer for the amount of time I had to spend on leaf pickup. It went from a dreaded chore to a 2-3 hour task.
