I have now a snapper 21" residential right now. I don't have many lawns right now with all that's happened(I'm in a fema trailer across the lake). So, I'm staying small until the truck, money, and more lawns come in to get a commercial walk behind or rider next year. This year I need a good commercial grade 21". I'm staying with small lawns. So what 21" should I get. I'm welcome to any suggestions. For some strange reason I was thinking toro or honda. The snapper pro doesn't seem any better than the res models except for steel wheels and a commercial engine. Also, what engine is long lasting and easy to work on the 6 hp Kawasaki ohv with pressure lube or the 5.5 honda gxv? I thought the honda was more durable. Any help is appreciated.
