The few leaf loaders I have found they want way too much for them. I do have a walk behind leaf vac but it doesn't do that well honestly and its the size for a push mower and about two strips fill the bag. I may try mowing them first and try sucking up the rest with my walk behind leaf vacuum.
I still think blowing them to the curb and sucking them up with a leaf loader seems like the fastest method. I mean really we can get usually have the entire lawn blown into piles within 20 minutes or less. But the tarping them into the back of the truck bed and taking a few trips to the dump site is very time consuming.
