This product is great for the cost, easy to store as it folds to a smaller size for storage in a smaller shed. Cutting adjustment is perfect to get the job done. Very reliable, and the power level is great. I can get a great majority of my yard done in the use of the battery provided. Charging of the battery is easy and quick. I would recommend it to others.

From a Joke to a Believer

From a Joke to a Believer I'll be honest — when I first bought this HART mower, it was kind of a joke. I didn't expect much. I figured it would get me by until I bought something “serious.” But let me tell you, I was wrong. Dead wrong. This machine has turned me into a believer. It cuts clean, runs strong, and has flat-out surprised me with how much work it can handle. If you want to really unlock her potential, do yourself a favor and invest in two 6.0Ah batteries. That's the sweet spot — plenty of runtime, plenty of power, no stalling out on you halfway through the job. Another thing I love? She doesn't tear up the yard when it's damp. I've run plenty of mowers in wet grass, and most of them leave ruts, clumps, and a mess to clean up after. Not this one. She glides over the yard, gets the job done, and keeps the turf looking clean. Bottom line — I went in laughing, but I came out impressed. This mower is the real deal, and I'm proud to say I'm a HART believer now.

I LOVE my lawn mower

I was honestly super nervous about buying this because I've never owned a lawn mower let alone mowed grass lol. I've either lived in apartments or my parents/bf did it over the years. I didn't want a gas mower because I didn't wanna deal with refilling it and having an electric mower seems easier because you just charge the battery and it's good to go. Just store it safely and clean out the bag when it's full. Simple right? Right! I have had absolutely no issues so far!! It was easy to put together, charges overnight and is ready to go by morning, it's not super hard to push, it takes very little effort and I love the different settings! I bought an extra key for it on Amazon as a backup since the key is small and I'm scared I'll lose it or my cats will hide it lol but I'm actually really happy with this!!! I just rented a house with a big yard and one charge mowed the whole front yard, back yard and the yard around the outside of me fence. I'm so happy with this! And it's PRETTY. It was the closest thing I could find to a white lawn mower and it's honestly so nice. I highly recommend it! I now enjoy mowing my grass haha JUST PLEASE DO NOT LEAVE THE BATTERY PLUGGED IN TO CHARGE IF YOU ARE NOT HOME! IT IS NOT SAFE!!! FOR ANY BRAND, ANY BATTERY!!! Unplug it once it's done charging and you'll be fine. But if you don't unplug it, these batteries can burn down your whole house. I LOVE this electrical lawn mower and I will continue to buy this brand. Give it a try! It's nice and easy (: once I figure out how to add my photos I'll upload some! Before and afters too!!
