Gooch I have the Greenworks 19" 40V battery powered mower and the 40V weed eater. My yard is only about 2500 sq feet. I have 2 batteries but one will mow the yard and weedeater. Takes about 40 minutes for all. I've used them for 2 years and they are great. I get the blade sharpened twice a year. Works like a champ, light, fairly quiet. No issues. I also have the leaf blower, trimmer, and chain saw. Happy with all of them.
