My little gas lawn mower is starting to show its age, so I decided to try to replace it with an electric lawn mower this time. I'm way more eco-friendly than most of the people who live here (most of them are Republican, who usually spit on ways to help the Earth to somehow "show the liberals") and I heard good things about these rather newer mowers. For years, they only had these in push, and that would not do. I managed to get one that is self-propelled.
One of the advantages to an electric mower is that obviously there's no gas. There's also no oil, belts, or spark plugs. Where the engine would be, is where you need to insert the battery. It's also super quiet too, sounds like a low-key leaf blower when the blades start to move.
It's also very light weight. My old Husqvarna mower not only had the gas engine weighing it down, but pretty high quality steel in its make. Which is good in many ways, but it would make me exhausted often times, even when it would push itself, most of the time. As far as the Kobalt's power, it cuts pretty darn close to the power and speed of a gas mower of a similar size and shape.
The downside is the run-time. I made a foolish decision to get one without a battery because I already had two. All the 40 volt series use the same type battery, but I didn't realize the two I got for my hedge trimmer and string trimmer were 2.0 amp hours. The one that comes with the mower is at 5 amp hours. So even with both of my batteries, I'm at 4/5th the run-time of what I could have gotten if I hadn't been frugal without research. That being said, the lesser batteries can still mow a good chunk of the yard before dying out, even with the self-propelled in action. For smaller yards or if you're trying to get places where a riding mower can't go, this would be a good idea. For people with big yards, this isn't for you.
