Anyone here own or use a walk behind leaf vacuum? Leaves are coming down and the beginning of my annual fall nightmare are here. I've been really thinking about buying a machine to handle the work this year. Are they worth the money? Before anyone suggests a tow behind that attaches to a lawn tractor, I don't have a tractor because my yard is just too tight for one and a trailer behind it would make it that much worse. So I am pretty much relegated to something that is walk behind like a billy-goat vac.
