I really like the Hustler line of mowers and could use some advice as to what particuliar mower to purchase. I will be mowing a church (about 4 acres) once a week, a neighborhood common area (about 5 acres) once every two weeks, and my home's yard (1/3 of an acre) once a week. This will probably last for two years max. I want to purchase something big enough so that I'm not spending my entire weekend mowing but I also don't want something that is too big for my small yard. I also want something that's going to last. I had budgeted around $4k but could pay more if the machine lasts me a good long while. I forget what my dealer said prices were since we looked at so many models. Could somebody give an estimate on the different Hustler model prices? I know they'll very, but I don't want my local dealer to rip me off. I know nothing about lawn mowers. Do I need a commercial grade or residential? I'd appreciate any advice.
