I'm glad I chose this lawn mower.
I'm a 69 year old woman, so having an electric lawn mower is great. I can't handle the self-propelled gas lawn mower any more. The batteries are small and lightweight and recharge quite fast compared to other batteries. The lawn mower is a little hard for me to push if the grass is longer and I have to go up an incline. I've only cut with it twice, but I really like this lawn mower.

Good Mower
I'd highly recommend this mower for ubran use and small lots. I've got .25 acres in Washington, DC and the battery lasts for a mow in front and back on the lot. It has a second battery that I keep charged, but even with a heavy/wet grass and it being taller, I haven't need the second battery for a single weekend mow yet

I love my mower!
I have 1/3 acre property and even when I let the grass grow tall, I can cut most of it on one battery. I love how quiet it is. No gas can or fumes to deal with. It cuts, bags, mulches great. I mow the leaves under the trees to chop them up and it has never had a problem with twigs. It's not so heavy that I have trouble pushing up/across some of the steep [parts of the yard. Turns on a dime with the larger wheels in back.

Of course I'd like a wider deck, but it isn't a deal-breaker. It is simply easy to use.

I've had my mower now for a year.

Electricity. Duh.
One day we'll look back and say " When I was your age we still used oil and gas." that was of course before drones mowed our lawns for us...

Does the side discharge chute need to be used with the mulching plug? I want it to mulch, but am unsure if it would work better with the discharge chute closed or open.
