We have too much land devoted to "the lawn" and too many trees that shed their leaves (and needles), and have used every leaf gathering/disposal device known to man-----including standing on our hind legs with leaf rakes in our hands----once---when we were younger and dumber.
THE SOLUTION: A DR LEAF and LAWN VACUUM a k a The Sucker-Upper (Google DR Power)
This device is towed by your riding mower which chops the leaves as many time as it chops them, and then discharges them as it does grass----only this time they're discharged into a chute carrying them to the Sucker-Upper. There they are met by a shredder powered by the Sucker-Upper's own engine (which also provides the power to create the vacuum), and then discharged into a hopper-----small, medium, or large, depending on how much you're willing and able to spend. And when I say a "shredder", what's left of the leaves varies from teeny-tiny pieces to powder.
Now if there's a downside to all this (and it will vary on the amount of leaves you have), it's what to do with what's left of the leaves. They're great mulch as noted above---if you have flower and vegetable gardens. We've used them to fill gulches and gullies, where they rather rapidly become plain old dirt capable of supporting 6-8-10,000 pound tractors. We've spread them in crop fields where they're disced into the ground. We have one little patch we call the burning pile field where we spread them out, and then run over them with a flail mower---and they eventually disappear.
And then there's this wrinkle which God thinks is hilarious. You Yankees are obliged to mess with leaves for two or three months (just like we are)----comfortable months. That's because you don't have Magnolia trees----those monsters the story books say we sit under and drink Mint Juleps. They dump their leaves in May, June, July---into August, and there'e enough of them on the ground now to have to tend to. We have three of those suckers---and one of them is a monster. I just went out and measured it----15 feet around about hip high----and 7 or 8 trunks from one base, and I have no idea how high it is; it just keeps on going----and raining leaves!!
Bottom Line: I have most every labor saving device there is, and the Sucker-Upper is my all time favorite. Aside from leaves, it also does grass clippings when your grass gets too long for whatever reason----and any and everything else that falls on your lawn. It even has it's own little wood chipper for when you come across a stick you don't dare run over with your mower.
