I just scrapped an ICE mower for a battery powered one. No more winterizing, changing oil, or worrying about filling with gas. I still don’t like mowing, but it sucks a little less now

Sure, but you're just deferring moderate yearly maintenance cost for a rig that will need to be totally overhauled in 5 years due to battery degradation with current battery tech offered in mowers

At least, that's the conclusion I came to this year when researching ride-on battery mowers vs ICE. Electric push mowers seem like a no brainer though

That's actually the situation I was in though. When your electric mower breaks you're probably on your own. I would not want to go back, but going forward definitely has it's own issues.
