I Love This Mower!
There are so many things to love about this mower. First of all, I’ve always hated the smell of gasoline every time I opened our storage shed, so I was thrilled when Hart offered up this mower for review through the Spark team. When the machine arrived, the first thing I noticed about it was it’s very cool, somewhat space-agey look. After reading through the instructions and charging the battery, which only took a few hours by the way, we decided to try it out. According to the instructions, remove the key put the battery in its slot and put the key in. Select the mowing height you’d like also. There are very clear instructions on the top of the unit also as far as how to start, which levers control the self propulsion and the blades, and there is also a speed control of the self-propelled mode, which is very cool also. I engaged in the slowest speed which was a perfectly good pace for me, you may want it a little faster. There is a mulch plug or a bagger that comes with the unit so you use either/or. And one of the biggest things I noticed about this was how quiet it is when it’s running. I think I could even more with 6:30 in the morning and not disturb my neighbors. I can’t say enough about this mower, so easy to use, it looks good and cuts well. And you can even store it upright so it doesn’t take up as much space as you might think. No negatives at all to report, give it a try.

Easy-to-use Hart SP Mower for a Disabled Female
I am a disabled female and was concerned about the weight of the mower, and whether the Hart mower would work for me even though it was self propelled. I bought it on Walmart.com. I did not load it into my car. A very nice man named Scott at the McCart Ave store in Fort Worth was on Walmart pick-up duty to load the mower into the car. My next worry was about unloading it because of my disabilities. I was able to push/slide the smooth-bottomed box out of my car. I slid the box out of the car onto my feet. It did not feel heavy at all. I already had another item to let the mower drop onto so there would be no impact to the floor.The smooth bottom of the box made it easy to slide around with my feet to allow enough room to roll the mower out, I sliced the packing tape, opened the box, and pried the heavy-duty staples out which was the hardest and most time-consuming part. I discovered that the mower was already assembled and ready to push out. All I had to do was extend the handle which snapped into place without any trouble like the instruction diagram indicated. I was worried about turning it on end to check for the piece of wood that the illustration indicated was underneath. They could change that. That part indicates how to change a blade, but confuses the buyer into thinking there is a piece of wood lodged like a safety piece you find while unpacking other items like printers or toaster ovens. Anyway, I put my foot on one tire and lifted. It wasnt any heavier than lifting my 13-lb bag of cat food . I rolled the mower out and nervously began doing something my disability has prevented years. The motor started right up with the push button. I set the Cruise Control on the lowest because I was afraid it would take off too fast for me. I pulled the self-propel bars toward me, and off we went on a nice leisurely pace. I didnt even have to push or pull to turn. Holding down one of the self-propel handles was like leading a horse in the direction you want to ride. The only problem I had with this experience was that I didnt place the bag correctly. I finally figured out that it was a user problem. My grass was mostly weed growth and quite tall. This mower tackled the job with ease. There were a few resistant-weed areas that I had to re-mow, but from what I remember about a heavy-duty gas mower, the need to re-mow a few areas again was the same. Weeds with stickers are awful, argh! I took a phone call and could hear above the noise; otherwise, the only thing I could hear were the stickers clicking underneath. It passed my disability test and the weed/sticker test. I can't wait to mow again, and to buy the blower weed-eater combo. That will have to wait to save up money again. When I go into my garage, I see my new mower stored on its end. I cant wait to mow again. I was a little sore the next morning, but Yay! I did it thanks to Hart and their building a mower that even I can use.
Best way ever to cut grass
This is the best lawnmower ive ever had. No gas which is so much better for out climate. Charge this mower in a few hours then cut my whole yard in one hour. It practically mowed the yard by itself, all I had to pretty much do was guide it where I wanted it to cut. I have to say this is the best way ever to cut grass.
