....for one that failed and was replaced under warranty. (I don't know where to dispose of the failed one for magical "recycling." )
The lawn mower uses one battery at a time, and I cycle through all three in a typical mowing session. Mowing my lawn can, and sometimes does, require three fully charged batteries. (I don't run them until they're completely discharged. Because of my bad back and bad hip, I'll run them down two levels, and take a break.)
For years, I insisted on shoveling the driveway and sidewalk by hand, since it was "carbon free." However my back and hip wanted no part of my ersatz holiness in the end, and I broke down and got the snow blower, under the quasi-mystical theory that if I spent money on a snow blower, it would no longer snow heavily. (For a while it seemed to work out that way.)
The snow blower doesn't throw snow the advertised 30 feet; with the wet snow I've used it for, it's more like five to ten feet, which is plenty for my purposes.
I don't want or need a leaf blower. I use the lawn mower to pick up the leaves and also "mow" the sidewalk in that way as well. I keep the mulched leaves to maintain the nitrogen cycle. Pine needles in particular are apparently rich in arginine or so I've read. (I'm a big time composting guy; at night when no one's looking, I confess to pee on the lawn for nitrogen and phosphorous for the trees. I rarely use commercial fertilizers, as I'm concerned for phosphorous and nitrogen for agriculture.)
I use an electric chain saw (corded) and a corded electric hedge trimmer. I would like an Ego chain saw, since it's a pain in the ass to string the cords out to the wood pile.
I can still split wood manually with an axe, an enterprise I used to enjoy in my youth as a stress reliever. However, there is, again the back and hip, no longer the possibility of splitting enough wood for half a winter in a single session of a couple of hours. A session might last only three or four thick logs, an hour at best.
I have never bought firewood, since we've had a lot of big trees come down over the years. Last autumn, that of 2024, I had the pleasure of teaching my son how to split wood with the axe. His girlfriend - also a nuclear engineering Ph.D. student - is from a semi rural area, and he made a point of calling her while splitting wood to let her know he was "manly" despite being from suburban New Jersey. I was greatly amused.
