Ratings may include incentivized customer reviews.
The mower provides a good cutting performance for small to medium-sized yards, with convenient features like adjustable height settings and a folding handle. The battery life is generally sufficient, though some users report needing to recharge for larger properties. While it struggles with very thick or tall grass, it excels at providing an even, clean cut on regular lawns.
Customer review summary generated by AI, including incentivized reviews.Easy start without any physical effort!!
I needed a lawnmower to mulch my leaves and this mower is perfect. It starts up extremely easily without any physical effort; it pushes easily; and it does a good job with the leaves. An added plus is that it looks attractive.
It’s very quiet and easy to operate
It cuts great, love it
Got it on SALE!
Best lawnmower I ever owned.
Plenty of power
Does a good job of chopping leaves and bagging for the compost bin.
Don’t buy open display model not worth the hassle
Great product but had to pay full price for display model even after talking to store manager even drove to another store when they said they had 2 but they only had one that was out of box
Obviously a Return
Paid to have this delivered. Clearly the box had been previously opened by the way it was packed and re-taped. Upon opening the box there were no instructions and no battery. Nice job Lowes. If you are going to take a product return then put it back on the shelf how about making sure that everything is still in the box. Now I have to take the trip to Lowes to return it which is why I paid $40 to deliver it in the first place, to not make a trip.
