Stone, I garentee you, you couldnt mulch those leaves!!! Just from blowing out all the perimiter beds in the back yard i had 2-3 ft of leaves around the perimiter of the back yard. My guess is that you would need to go over this lawn about 8 times with double blades to mulch those leaves to an eceptable size....and even that would be useless because it wouldnt mulch the acorns and sticks everywhere! Btw, why is that the wrong mower for the yard? If it fits...I use it!
