My brother-in-law picked up a used Agri-king lawn vacuum to tow behind our cub cadet mower. When the leaves come down fast and furious it's the only tool in the arsenal. It has a standalone five horse motor on the tongue the runs the vacuum and it holds about 3 yards of chop leaves. It's probably the best thing we've ever purchased to use in the garden, as all those leaves go right on top of my mulch beds in the fall.
