Have used it twice on my yard, which is not the nicest yard. Sloped a bit, more weeds than grass, small branches galore. First mow took 1 1/2 hours, used 2 and a quarter batteries to get it done. Second mowing, things were a bit shorter, 45 min to mow, all on the battey that came with it. Mower works great. No issues at this point. I own several grren works tools and have been happy with them. I bought this mower specificaslly because I can use my existing batteries with it.
I have a relatively large yard, around an acre, and I have been able to complete the mowing on one charge with spare battery left. I really appreciate the quiet while mowing after many years of noisy mowing.
The mower is great except for a few minor issues: When it is propelled forward and you stop, it takes a long moment for it to disengage It would handle a bit better with swivel wheels optional on the front. The forward motion clutch is a bit cumbersome with a lever to engage but also another button to set the speed of the forward motion In the end, I have mowed lawns professionally and I own all Greenworks lawn equipment and would buy then all again The battery power is very good, it cuts the grass great,
I have spent a lifetime using gas mowers. I take pride in adding gas stabilizers, drawing fuel in the fall for the next season. Still many times I needed to rebuild the carbs. This unit is a beast and quiet. I will never do gas land scape equipment again as mine fail
