    • Cuts in more ways & Fits the Bill
Size: 21" Mower (2 x 4.0Ah)
Cuts in more ways & Fits the Bill My Greenworks 40 Volt Self-Propelled 21" mower was purchased with 2 - 4Ah Batteries + charger from Amazon as an Earth Day Special 4/22/2021. The shipping weight of the unit was 82 Lbs, packed well/secure and received new the next day. Batteries were at 1 LED when indicator level was depressed. Assembly was quick and straight forward. The build felt solid and heavy duty for me -- having upgraded from a substantially lighter corded plastic 13 amp 16" push mower. The decking of the Greenworks is steel, along with the welded wheel frame, single levered height adjustment, grass catcher basket and hardware. All four wheel spindles are encased with steel ball bearing races. This machine is robust and sturdy. My long wait is over, yes, I've graduated to cordless mowing! After 4 mowing sessions in the couple of weeks of my roughly 102' x 48' NE back lawn consisting of mainly dense established fescue, I am very satisfied. Here's are the pro's: 1) The cutting power and torque of this brushless mower powered through my well-watered spring growth, impressively. There were no bog downs, unlike my underpowered corded mower past, which caused me to pop "Wheelies" over the dense high spots of the lawn. I had to go over the thick growth, with the old mower, at least a couple of times or mow at a higher setting first and then drop down a notch to make a second pass, or more. The Greenworks hums through and ramps up when needed but it is still much quieter than my old machine. I opted not to use the rear wheeled self-propulsion which was too slow for my taste (my goal is to mow the back lawn cordlessly in 35 minutes or less) maximize cutting /+battery economy and push the hefty steel unit hard and fast to get a good aerobic workout, as well. No fumes, oily mess and extension cords to worry about running over! 2) Battery life is as expected. I can cut about 65-70% of the backyard on one 4aH battery with 1" - 2" of growth with a fully charged battery at around 41.2 Volts according to my meter. This is as expected. I will probably just mow half my back yard in the future, empty the grass catcher then alternate batteries to prolong overall battery longevity and prevent life-shortening battery overheating and overdischarging. I always mow near sunset to help keep the batteries cool. As a routine, wearing leather gloves, I sharpened the blades with a fine flat file for 1-2 minutes between each of the three mowing episodes to assure cutting efficiency on that chosen day. The fourth cut was done after a rainy day without the usual sharpening and the last 25% was done in a light, but steady rain. 3) The center-mounted grass catcher fills very well. I never used the side discharge plastics. I am very pleased that the cut clippings end up in the bag and not strewn across the lawn. My third session averaged about 14-18 Lbs of moist clippings around five bagfulls, close to a hundred Lbs. The blade rotation and angle design is very good, forcefully blowing the cut lawn clipping into attached the mesh grass catcher. Emptying is fast and easy. During the rainy day cut, I was duly impressed. The machine handled the abuse and cut admirably. My bag fills were heavy, full of wet clippings, probably double the normal weight of the bagfulls accumulated during my other 3 sessions. I would never mow like this with my corded unit (electrocution hazard). I alternated the batteries every one or two bagfuls to keep them cool and charging since the system had revvvved-up significantly due to the resistance of the stickier wet grass. The bag was surprisingly filling to the full and the trails of grass left in my lanes were amazingly minimal. For all 4 mowing sessions since my purchase, the cut height was set at the "3" level. 4) Black plastic handled spring mounted pull clips with steel pins make storing the mower vertically convenient, as well as, giving sturdy access to sharpen and clean as needed. (The three position handle adjustment plate has a fourth set of holes in it that transforms this steel bracket into the mower's vertical kickstand. Pre and post maintence is a snap for me, because of this feature. 5) The self-propulsion can be initiated without the blade spinning. After being winded from a good pushing series of laps up and down my slightly graded yard , I was pleasantly surprised to find that the rear-wheeled drive works when I turned the center gray circular knob to the "Unlocked" position and welcomed the assistance at the end of my mowing workout. 6) What incredible foresight and consideration on behalf of the designers and engineers of Greenworks, that each of the 4Ah batteries come with a 5-volt USB charging port! Being Green works... I have paid extra for this feature for an attachable device that's connected onto a competitor's batteries in the past. The self-closing USB slot provides a dustless connect for owners to charge their devices. I've been storing my mower batteries at their happy place at either two or sometimes three bars and getting double duty from my mowing investment by charging my portable electronics at home. I have now cut off the AC power to my DC chargers since the batteries have juice to spare and provide worry-free clean power that is essentially free from potential device damaging storm/transformer failure induced spikes and surges and now I just burn the Kwh's I will actually use for the small electronics. No more wasted Kwh's idling. I just top off my Greenworks batteries when needed to prevent overdischarges and keep them at the preferred best storage voltage of around 2 LEDs to assure a long productive life. I charge them to 4 bars at 41.2 Volts right before I mow. I've discovered that according to my meter a starting voltage at 3 bars must be less than 40.3 volts to initiate a top off charge. Here are my cons: a) Batteries when heavily used will overheat. Alternating batteries if possible and allowing for cooling time between heavy use, I believe from my research will prolong the batteries overall longevity. https://www.protoolreviews.com/lithium-ion-battery-maintenance-tips/ b) Batteries tend to get hot when charging. Interval charging is what I've found useful and have programmed a timer to "baby" my batteries to coax the highest level of productivity from them. I like the mower and have anticipated hotter working conditions and purchased a set of Greenworks Bluetooth mobile device (iOS & Android) connectible 3Ah batteries to meet my mowing needs. For my future mowings I have the option to wirelessly monitor power reserve levels and temperatures. I will be rotating my batteries frequently between bag changes to get the most life and capacity from my mowing investments. c) Charger can time out when overheated and must be given time to cool. I've found that once cool, the charger should be unplugged for 10-15 seconds to clear the protection circuit. Now, I can begin charging, as long as, the battery is cool and within the recommended charging range. d) Self-propelled mowing may be out for user's that have larger areas to cut. The pace maybe simply too slow for many like me, whose territory and priority is to cut and bag, as much as possible, quickly. Mowing efficiently and promoting the longevity of the equipment is my key priority. I want the batteries and mower to last for many, many seasons and cutting the most square footage per charge while getting a good cardio workout. Users with smaller properties to cut or hilly terrain or perhaps folks who are physically not inclined to be pushing and pulling a mower in the near 65-100+ Lbs range (side discharge only- full grass catcher plus two batteries), the slower pace, in all fairness, is not necessarily a "Con." The cut and control are good for this unit. The self-propulsion is smooth enough but when reversing, "pull gradually." A hard pull in reverse on the handle will be tough on your wrists since hard plastic yoke control slides and can "slam" against the steel handle assembly. If yanked abruptly, however, if you anticipate your reversing... and reverse gradually and purposely---the rear-wheeled drive system will work along with your course direction. It's kind of like dancing with a good partner but can be feisty and hesitates in reverse if you want to move faster with back and forth pivots and pull backs in tighter areas. Summary: This unit is a vast improvement from my corded experience. It is a well-built and powerful machine that cuts and bags well. It has saved me time keeps me in shape, lowers my electric bill, preserves my personal electronics and is built to last. The batteries and charging system can do the job that I am asking them to do. But I must manage them and have bolstered them. The limitations of the batteries and charger are evident for my needs and my environment but worth the effort and the price I paid along with the consideration and extra set of batteries I've already added to prolong the investment. It has surpassed my expectations and has given me more benefit despite the extra burden of taking little breaks swapping batteries and dumping clippings. I need the rest anyway and my mowing sessions are more like a "Tabata-Styled" interval workout. For those who live in hotter, drier environments with heavy or very hilly or large areas to cut, this unit may not be as workable or care-free as you would want and may be a pass, but for me it works. This system keeps me, my electric bill and my yard "Fit and Trim." ... show more

    • Great Mower
Size: 21" Mower (6.0Ah)
I have had this mower for a few months now, so I feel like I can finally write an informed review. Pros: - it looks like a normal mower, that may or may not matter to people, but I like what I'm familiar with. - It is quite. I no longer use ear protection mowing the lawn. - It is light, so my son that had a hard time manuevering an ICE mower has no problem with this. That means I don't even have to mow the lawn if I don't want to and my son wants some extra money. - I got a really good price here on Amazon and it came with this 6AH batterty, which is a battery with a lot of reserve. This battery will mow my entire lawn by itself if I don't use the self-propelled function too much. I have a 0.18 acre lot with a typical two-story 4 bedroom/2 car garage lot. - The batteries are interchangeable with the 40V Greenworks leaf blower and chainsaw I have. I had to use a backup battery I already had one time, which came in handy. - The battery has BlueTooth! I have never seen that before, but you can use your phone to get vital battery stats. Who knew that was even needed (it really isn't)? - Since it is light I don't feel the need to use the self-propelled function much, which is a good thing (see cons) - It srotes vertical, which is really nice when your garage is space limited like mine. - No Oil Changes, Spark Plugs, or Gas Needed! Cons: - If I use the self-propelled function on my average lawn, the 6AH battery it comes with doesn't do the whole job. However, The one time this happended was the first time I used the mower using the self-propelled funtion mostly the whole time like I used to do with my old ICE mowers. I realized with how light this is, you really don't need the self-propelled function except for hills, and I haven't had the battery run out on me since. - The blade isn't very substantial. WIth the old mower I ran over sticks and stuff, not thinking about it. With this I make an effort to make sure there are no sticks in the way. Some would say that is what I should have been doing all along. - This biggest issue I have, which I don't have much, is the self-propelled function is not good. I'm used to pulling the bar and off it goes instantly and being able to feather the speed. This has a bit of warm up and then full oomph lifting the front. It's like nothing, nothing, okay something, and then full speed. The throttle is adjustable via old school rabit/turtle slide switch, but I find it hard to find the sweet spot. Ultimately, I learned that I really don't need to use the self-propelled function much. I'll update this review if I have any break downs or broken parts. Edit: 1 year update, still running great. Wish I would have converted to battery a long time ago. ... show more
