Despite the fact that I still go out and mow my parents lawn, my mom still wants/needs a new push mower. My dad refuses to do the Wal-Mart special so I have to find him a commercial quality push mower. I'm picking up a new turf tracer in about a week and I was wondering if I should just add one of their push mowers to my order. So, good, bad, indifferent. Is the 26in that much better than the 21. Is it worth the Exmark price?
