Arrived defective
I like the stats on this mower. I am 75 and thought it would not require muscle to start or operate. It arrived and looked good. However it was inoperable because the safety was frozen in the down position. It is supposed to always be up except when squeezed to operate. I wrote the manufacturer with pix. They said get Amazon to give you a new one. Called Amazon. They said talk to the manufacturer. After repeating myself that I had talked to them and could send the email with the manufacturerâs notion that I should be sent a new one, Amazon said I should send them back the mower. I had already told them I was 75 and not going to find a box, the time, or strength to repack the unit. They said if I repacked the unit, they could pick it up. Again did not understand that I was not going to search for a huge box. I had cut open one side of the box to roll out- not lift – the mower. I threw that box and the packing out before I understood the problem. I have done the pick up thing before and waited around 3 hours for a pickup window that they missed. I have already spent 11/2 hours trying to address this. I make 70-150/ hour. The mower was a little over $200. Your circumstances may differ.

Perfect fit for my lawncare!
This mower is fabulous! Easy to push, light weight and can tackle overgrowth with ease. I’ve used it all last year and started using it again this year. I’m impressed with the battery strength and the two speed motor! Yes, the motor will kick into a higher gear when cutting taller grass. I love it over my Toro self-propelled gas mower. (which I got rid of, due to annual starting issues.)
