A while back I posted the ad below, and someone picked up the mower mentioned. I just discovered a box of stuff I had for the mower (including a blade), and I'm hoping the person who picked up the mower (or someone else) can use it. The mower is an Earthwise 60120 20-inch 24-volt cordless electric lawn mower.
Everything I have now for this mower is shown in the picture.
I moved a couple years ago from a small lawn to a big lawn. This mower was great for the 1/2-acre lawn, but I don't use it anymore with the big lawn.
I replaced the batteries in it shortly before I moved, six years ago. They still show good and report no bad cells or other problems on my BatteryMinder, and the mower shows that they charge and have fully charged, but they don't run the mower very long so they probably need replacement. I haven't looked into that so I don't know if the problem is fixable or not, but with the $0 cost of the mower, getting replacement batteries shouldn't be cost prohibitive. If you replace them, battery stores will recycle them for free.
