I don't have a dainty little suburban lawn to mow. I have about 3 acres of hilly, rutted, sometimes overgrown Appalachian field around my house. I've always resisted riding mowers simply because cutting the grass is such good exercise, but I've always used gas-powered beasts for the job. But...I've had an EGO chainsaw and trimmer for years and have been very impressed with them, so after watching dozens of Youtube videos and reading reviews of this mower, I took the chance and got it.First impressions - I love it. On the first session with a brand new, freshly charged 10Ah battery, I wore out before the battery did. (Hey, I'm 69 years old. Gimme a break.) After a full hour of mowing the battery had just dropped to the 20% mark, so I have no doubt it would have made it the promised 75 minutes (if I'd been up to it myself). And having a second battery charging up and ready means I'll never have to worry about it.I was using the mower in the setup it ships with - mulching blade and plug, and the grass looks perfect. I understand that using the "extended runtime" blade should make the battery go even further. I'll try that next time.The EGO is much quieter, lighter, and more maneuverable than my Husqvarna mower and, on first impression, more powerful. The self-propulsion got me up hills with no effort, and the mower is light enough that I didn't really even need to engage the propulsion on level runs.I have only two minor gripes.1) If you look closely at a photo showing the bottom of the mower housing, you'll see lots of little baffles and crevices where cut grass accumulates. This makes scraping the bottom of the mower off a bit aggravating. No big deal but still - I wish they'd made that a smoother surface.2) The EGO mobile app that should monitor the battery status on my phone while it's charging has so far failed to connect to my wireless network. I've followed directions exactly, and a quick google search tells me there are plenty of others who've had the same problem. Not a major issue (it's easy to see the charging status on the charger itself) but still, they need to work on that.Other than that, I'm much impressed. I will not miss dealing with gasoline, oil, air filters and spark plugs. Well done, EGO.
