For the amount of usage, it wouldn't have been a bad idea for you to have fuel stabilizer in your fuel cans. Ethanol attracts water. Water no goody for Mr. engine. In all seriousness, with your space, I wish ya well. I'm sure those fold up nicely too, less mess ETC. If "I" had 900sqf of grass, I'd be using my wacker. I'm kinda fancy with the wackageWe don't have winter here. We have warm and not so warm. Sort of boring if you ask me but people seem to like it.
I had a gas mower and I was constantly fixing it, fueling it, something it. I'd spend an hour getting it out for the bi-monthly mow and 15 mins actually mowing the lawn.
It has it's place in suburbia where the water is scarce and the yards are small. The yard is small enough that I can mow, whack and blow on one battery.
I'm about ready to plant rocks to be honest.
