Try a quality battery operated mover. I own several 40W Greenworks products like chainsaw, pole saw, drill etc., all are very good and require almost no effort. I presume the mowers are good too. I'd probably go a little higher end on a mower for durability.
Battery tools are really trending. There are country boys all over Youtube trading out their gas chainsaws for battery operated ones. You'll be shocked by the power, lack of effort and relative quiet of them. The best thing is they work perfectly after months of non-use. I have a chainsaw and a weed whacker in Vermont that I only use a little bit in Summer and Fall when on vacation there. Both are worry free, just charge the batteries and go. They are the future.
