yeah mulching the leaves up first is a GREAT space safer.
I have a 6 foot bed and I can fit roughly 8 houses worth of leaves in it at the beginning of the season doing them weekly.
by the middle I have to empty the truck twice a day and by the end I'm back to emptying once a day.
next fall I'm gonna talk more people into letting me dump at the curb. our city picks leaves up twice during the fall season and tax payer dollars pay for that. so they might as well get that benefit.
