This is our second year in business (two sons and myself). I have a full time job and do this after work and on Saturday. Last year we had about 10 accounts and we were mowing with a Kubota 40" tractor mower. This year we would like to get more accounts and I am looking for a good ztr. I ask the dealers and they always say theirs is the best. I asked one repair shop here in town and he said grasshoppers are great because of lower repair cost. Also, would anyone recommend buying used and what is the best size for residential? Any suggestions. Thanks.
