Due to pandemic desired a mower which was battery-operated. This unit fits the bill perfectly. Have not run the unit to the point of total battery discharge but have mowed for 45 min. periods. Light weight. On slight slopes you almost do not need to use the self-propelled feature.
I am very pleased with this product after just one use. The battery charged in under an hour. Height adjustment is very simple and easy to do. Starting involves the push of a button...no more cord pulling. The speed adjustment of the blade takes a little getting used to. Some grass clippings are left on the lawn in thicker areas. I have 3/4 of an acre, and battery easily lasted as long as I needed.
No problem cutting 1/2 acre lot with two batteries provided even had surplus charge on the second battery. Unbelievably quiet compared to regular combustion engine.
I replaced my 20 year old Honda self propelled mower with the Greenworks 21" non self propelled and am very happy with my decision. My yard is very small and takes as much time to edge the sidewalks, driveway, fencing as it does to mow. It only took less than 1/2 charge from a 2ah battery to mow my yard! Disclaimer: I own several motorcycles and drive a gas guzzling suburban. This was never about my desire to save the planet, it was about buying a mower that is easy to use, easy to maintain, and does the job. Mission accomplished!
I purchased a Green works 21" Cordless, Brushless 80 Volt Self Propelled Lawn Mower 3 weeks ago. It is GREAT. This electric lawn mower is actually fun to use. I can mow the front and back yards and only use 2/3 of the battery. Recharging is really nice as it only takes approximately 45 minutes for a complete recharge. It is easy to use and clean.
I bought this a month ago and I've only mowed once but wow! It does everything my old Toro did, the battery lasted more than 1 hour. It recharges really fast. Only negatives are the release on the mower to remove the battery is really stiff. I already split a nail. The mulcher doesn't seem to do well with leaves but it may be a height issue. I need to play around with that some more but again, wow!
