July 25, 2024: Sharing a little trouble-shooting info.
If the battery gets overheated, the mower will just stop. I had this happen & I thought the battery needed recharging. If you pop the battery into the charger this way, you'll get the red indicator light. The battery simply needs to cool down first & then it will work again. I'm now storing the battery inside the house, not out in my garage in 90+° temps. Overheating it, as well as keeping it sitting on the charger 24/7, will eventually deplete it's capacity to hold a charge. Hope this helps.
Update #2: The mower powered through a huge area of thick, knee-high grass in the backyard. First time cutting it this year. I also did the front at 7am & the grass was wet. Mower ran like a champ. After removing the battery, I tipped the mower on its side, cleaned the underside with a small putty knife, gently rinsed it with the garden hose & let it dry. Mower still works great.
Update #1: Mower continues to perform very well. The battery is tricky to remove. It has a release button on it that has to be pressed down at the same time as it's pulled out. I put the handle of the mower up against the siding of my house & it keeps the mower from rolling as I get the battery out.
OG Review: First time I've ever tried out any kind of battery operated yard equipment. I'm tired of paying the lawn guy to cut my entire yard when it's only the front area that needs to be consistently mowed.
This mower arrived brand new in the box. I had trouble with the handle assembly & the two sets of cam locks because they don't tighten and clamp down the easiest. That took a few tries. The battery slides into the charger which blinks green when charging, and then stays solid green when charged. The battery clicks into the top of mower much the same way. The battery has a power indicator on it - press the small button on the end of the battery and there are 4 lights that show the amount of charge. Starting the mower is sooo easy. It takes about ~5 seconds to get it powered on & instructions on how to do so are printed on the mower by the starter button. If you need to stop the mower, release the bar. Stopping & starting the mower up a few times was no problem for me. The lever on the deck that adjusts the mower height moves easily and locks firmly into place.
My first test run of this mower went well. I did my entire front yard and around the side of my house in 35-40 minutes with a battery that was still going strong. The mower will speed up if the grass is thicker & runs slower for less dense areas. I'm not using the grass catcher, so no idea how that hooks on or performs. What I really like is how lightweight the mower is and how quietly it runs. I doubt my neighbors across the street could even hear it.
One important piece of info that I'll pass along. After watching a YT tutorial and review on this mower, it was recommended not to keep the battery sitting in the charger 24/7. Charge the battery just before use, recharge it again after and then take it off the charger & store it separately. Doing so extendss the life of the battery.
Overall impression on this mower:
Easy startup, runs super quiet, it's lightweight so that you hardly exert any energy pushing it along and it has a long-lasting battery charge. For me, this mower will pay for itself in just 3 uses (I got it on sale) and I'm excited to finally be able to cut back on yard expenses. I'm also thrilled that I don't have to be bothered with the fuss of fueling & and winterizing a gas-powered piece of equipment.
