As far as mulching leaves in the fall, I would say with the exmark 30 you could do small to moderate leaf mulching if you slow the machine down. I had a few birch trees dropping leaves and some after storm trees losing there leaves and the exmark 30 did a great job mulching the leaves. I was surprised. As far as large amounts I would say no. Your idea of cutting in the fall weekly and mulcing leaves is what we do. Alot times what we do is mulch first then bag and drop them on the street. We have curb side pick up with all our properties. I charge extra if there is a large amount of leaves. I charge a mowing price if the leaves are not bad. I figure you don't have edging and string trimming to do at that time it works out well in our favor. If any one skips a week I charge more. I cut weekly on most of my properties till the end of November. The people like it because there property always looks good. The last cut I will blow the beds out mulch and bag leaves and charge some extra. Some people have me blow the beds out during my weekly cuts were I will charge extra. People like this method better then them raking and there not being hit with a five hundred dollar bill and there property always looks good. If there is a large amount of leaves we blow them to the street or blow and tarp to street, then we go over the property with the mowers. Our properties are all half acre and down, most are 10,000 to 12,000 square feet so it doesn't take long to maintain this size. Last point if it's real wet I do think it would be a problem to mulch with the 30's.
