What Customers Are Saying
The electric mower offers powerful and efficient cutting performance, able to handle moderately tall and thick grass. The self-propelled feature provides good traction and maneuverability, especially on slopes and uneven terrain. It has long-lasting battery life, with most users able to complete their entire lawn on a single charge. The mower is lightweight and easy to use, with simple height adjustment and intuitive controls. However, it may struggle with very tall or overgrown grass, and the self-propelled feature can sometimes be too fast or sensitive. The battery life could also be improved, especially when using the self-propelled mode extensively.

Problems
No way to shut off self propelled. there are times when self propelled does not help but causes problems. Due to weather, I've not been able to mow much but cutting up leaves seems to be a problem for it and that was the main reason I bought it.

Thank you Lowes for providing the sale of this Kobalt Gen4 40 volt, 20 in Self Propelled Battery Mower. I have a Cobalt 40 volt mower but I needed Self Propelled. Kobalt in my opinion is the BEST!

Expected more
For the cost, I was very disappointed in the overall performance of this mower. I purchased it for mowing a small ditch that was too steep for my zero turn mower. I kept my grass mowed regularly, so it was never overgrown. However, this mower would cut off when I would mow, grass would build up underneath instead of throwing it out the side. Also, the battery worked great the first 5 or 6 times. After that, it gave out after 45 minutes

Lawnmower,
Not as as good as the first one, I bought 2 1/2 years ago, the lawnmower looks a little cheaper. I understand that you gave me a little bit bigger battery, but the whole unit was not as good as the other lawnmower I had, which is the same lawnmower, different. I can tell.
