Please forgive me for asking a question that's probably been asked before, but I can't find it in this forum. I need guidance on the best mowers to consider for a nonprofessional. I have a double city lot on a hillside in West Virginia. The yard is rather steep in places. I wear golf shoes to mow because of the slopes. Please advise me on the best commercial or non-commercial mowers to consider. I don't wish to spend more than about $500, but will consider spending more if you all think it's worth the extra money. I really don't want a two-cycle mower because of the high noise and pollution produced by two-cycle engines. I want a self-propelled mower, with variable speed being my first preference, though not a requisite. Mulching is not something I've been doing, so it's not a factor for me. I currently use a cheap, $100 Southland mower with a Briggs & Stratton engine. I very much appreciate your help.
