When Joseph mows, we have him use the grass catcher. Sucks those leaves right up, chops them up, and he can dump them right in the woods in the back! Heck of a lot easier than raking, that's for sure!
I've got a grass catcher for my mulching mower. The problem is that it's not very big. That and the mower won't start unless it's installed correctly and I've never been able to get it right.
