Oh, heck! If I had to shred my leaves, I'd be lazy too. In the fall, DH uses the lawn mower with a bag to catch shredded leaves. I did buy a leaf blower/vacuum thingie but it doesn't shred the leaves that well. I have oak leaves which are quite leathery and take a year or more to break down if not shredded. But supposedly adding coffee grounds is supposed to help them break down and turn into some mighty fine compost.
