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 Hart 20" Mower!

I absolutely LOVE my Hart 40-Volt 20-in Brushless Push Mower. It provides an awesome cut that is so clean that my yard looks like carpet when I'm done mowing (a nice and even cut over my entire yard). This mower is easy to set up and collapse for storage! This mower provides plenty of battery charge time (40 minutes), it is a low noise mower which I also love and it's easy to maneuver! I would definitely buy the Hart brand again! Thank you Hart, well done!🙂

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!!
