Belt drives have their place, but the beauty of being able to back up a hill and not have to see a doctor for a hernia afterward is very, very nice. I would be interested in a 30" push mower. We actually have a few yards that the customer demands they be push mowed. All of them are less than 1/4 acre, so it's not bad, however it is still time consuming. Their saving grace is that they are all clumped in with adjoining properties that we service, so one guy is push mowing and one guy in on the ZTR/WB and one is trimming.
