I mow residential homes (senior citizens who only want lawn cut once a week).I am looking to go from a standard 22" to a 32 to 40 inch walk behind. However in the area in which I live the dealers seldom sell them and are of little help in helping me decide what to or not to look for. What do you the professionals suggest? I like the idea of going hydro over gear, don't really want to go over 36" deck due to maneuverability on small lots. Prefer to mulch over bagging. I never side discharge since grass is normally 3-5 inches tall and it looks bad. The brands I am currently interested in are:Billy Goat 33", Simplicity 1534 pacer, Wright Velke, and also have considered the Ariens mini zoom 1534 rider. I also have had some trouble with carpel tunnel in my hands. Thanks!!!
