I bought this Makita lawnmower (this exact one on this site, so I was informed by Galaxus that you had asked a question) last spring because we moved to a place with 500sqm of lawn, half of it almost 80% slope. I was very sceptical about the wheel drive on this steep slope (I can hardly walk there myself, it's so steep, but the mower goes up there all by itself and pulls me along) and about the battery power... But when I mowed for the first time with 4 full 6Ah batteries (a total of 24Ah, more is not possible), and after 500 square metres I had not even used 50% of the 24Ah capacity, I was totally thrilled and celebrate this lawnmower to the fullest. I can only recommend the device and have not discovered any disadvantages or negative features so far.
