Rated 5.0 out of 5.0 by Great Mowjoe! Goodbye heavy, smelly, noisy, gas guzzling, polluter! Just right to mow my 250 sq.yd. lawn twice on a charge. This machine is light, quiet, mulches or not, and makes mowing a bit more enjoyable. It has very simple features and controls. August 19, 2014
Rated 5.0 out of 5.0 by What a little miracle mower I have been mowing lawns on my own for 20+ years. I'm a short gal and have used gas and electric corded mowers. I'm sick of them ALL. So I decided to be done with the gas and electric cords and try something new. I purchased the leaf blower with this so that I could have the charger and battery as well for the lawn mower-it was worth it because the other 2 components on their own were just as expensive. So I get the lawn mower home yesterday, and my grass was in such bad shape. It's May now and the very first time I've even begun to look at the lawn. No joke-it was at a minimum of 6 inches of outgrowth. This little bad boy cut threw it like a hot knife through butter. Make sure your battery is fully charged for a 1/2 acre lawn. I used the highest setting-and to date I have never seen a mower have such GREAT clearance for an overgrown lawn. What a solid product. Just amazing. May 15, 2014
Rated 3.0 out of 5.0 by Could be better... I am coming from a corded 20" mower, which I loved, but wanted to try a cordless to see if it was faster, easier. I bought another cordless, but it weighed 100lbs - exhausting for maneuvering - even with self propelled. This one is SUPER light for turns and maneuvering around shrubs, etc. This one is 16" and means I have to make 25% more passes - the front end is about 13" and the rear is 16". Not a workhorse - battery drains for higher grass or good, thick St. Augustine in Texas. If you mow every 5-6 days, you're good, anything else - more work, battery runs out. Cuts big 1" chunky pieces, not a fine mulch - must bag if more than 6 days growth - extra work and trash bags. Does not cut St. Augustin crawlers - see pic. Battery charges fast, but drains fast - I had to buy an additional battery $$$$ to get through my front yard in one session. Good for tiny condo yard or a smallish yard with Bermuda grass or weedy grass - not for a good, healthy LAWN. It is light and you can go pretty fast, but I'm not happy with it overall. It's not very powerful, so you don't get a really clean cut lawn, just a passable looking result. I'm not gonna mow 5 times a month to make this a good mower... July 22, 2014
Rated 5.0 out of 5.0 by The right tool for my yard! I was skeptical of whether or not the battery and power would hold up, but this mower handled the job with ease and battery reserve to spare. Smooth push mower! Great battery life! Easy to assemble. I got the set and the interchangeable battery is wonderful!! October 22, 2014
Rated 5.0 out of 5.0 by Way better than priming and starting an engine! I have the mower and complimentary edger. I got battery and charger with the edger, so I ordered the mower without charger and battery on line since the store didn't carry it. I used the same battery to edge, then put it in the mower and mowed our yard on the same charge. My wife even likes it! She couldn't get our old gas mower started, let alone push it around our sloped yard. The mower is so light my wife can even mow and she just has to grab the handle to start it. No cords. One grab handle sets the mower height like shifting my hot rod! Super easy! Charge the battery when done and its ready to go next time, no delays! It folds up with quick release handles and I store in a little corner in the garage. July 11, 2013
Rated 5.0 out of 5.0 by Love the Mower I've used it twice since my purchase works just like I expected runs smooth and quite compared to my gas mower plus no more oil or gas to deal with and/or store, and no extension cords, Happy April 9, 2013
Rated 4.0 out of 5.0 by Good for Small Yards. I ended up having to buy this mower because the one with batteries was out of stock. I also purchased the blower and trimmer to get the batteries. Good news is I now have 2 chargers and 2 batteries. I have a pretty small lot, with maybe 0.1 acre of grass. The first time I used the mower, the grass was pretty long as I did not have a mower and the previous owner did not mow recently. This mow took over 3 battery charges to get through. The second time I mowed, a couple days later, the grass wasn't as long, but a bit damp. This mow took over 1 battery to get through as well. I was hoping to get the (tiny) yard mowed on a single charge, but that doesn't seem like it will happen. Perhaps bagging would be slightly more efficient? I am on the highest height of the mower, which is 2.75". I wish it at least went to 3". The mower is simple and light enough that my wife can use it to mow as well, which was a bonus going for electric. One complaint I have is that the quick-release knobs stick out a bit from the side on the handle, so it is a bit difficult to get close to the wall (or my neighbors picket fence). November 4, 2013
Rated 5.0 out of 5.0 by Easy, convenient, and cost-effective... To start off, I'd like to disclose that I have only had my mower for a few months. Being it is so new, I could not - in all honestly - rate the product "Excellent" with the "Quality" tag and "Value" tag. I am comfortable in stating that the "Ease of Use" was / is in fact "Excellent" ... a simple push of a button and flip of a safety lever and the mower is off and running. I was also in agreement that the "Features" are "Excellent" in my opinion in that what I was looking for in a battery operated machine with ease and low costs was truly presented in the Ryobi 40-Volt model. Now, on to my "review"... I have a fairly small suburban lot size. In Florida, that pack the homes tightly together to accommodate all the demand. Therefore, I was okay with attempting to tackle the Saint Augustine thick ground cover with a battery operated machine. My yard - including front, sides, and back - is no more than 1/8 of an acre (an acre being slightly over 43,500 square feet). I am able to cut the front, both sides, and part of the back yard on one battery life, then swap it out for my spare to complete the back, then use it with my Ryobi edger and then swap it out to use in my Ryobi weed trimmer with still some battery life left over. I was truly amazed that the batteries lasted as long as they did. Again, my yard is rather small, but I do edge all my driveway, sidewalks, and landscaped areas ... then, trim with the string trimmer, the house edging, around power boxes, etc., and mailbox, et al. My next purchase will be the Ryobi blower so that I don't have to sweep up the driveway and sidewalks with a broom. I am pretty frugal; thus, did not want to spend unnecessary financial resources on gas, oil, and maintenance of my tools. I have had the experience of owning gas mowers and trimmers and edger devices ... and in the end, there is much to consider with these powerful alternatives to a battery powered device. For me and my particular yard, the Ryobi 40-Volt line is all that I need. The final test will be how long the batteries last and / or retain their charge. In Florida, it is rather hot in the garage; therefore, I store my 2 batteries after they are fully charged in my indoor laundry room. There they are cool until use the following weekend. I want to again lead with the reminder that my yard is not very big, but for double the size, I still feel that my Ryobi would handle the task with easy and low cost. I may choose to buy the 2 battery option though. Since I already had an edger and trimmer with a battery and charger, I chose not to buy to combined mower with 2 batteries and charger station. Again, a larger yard and I would have another battery on hand. Secondly, when using the mower without the bag attachment (see my pictures), it seemed the mower was not as efficient and easy to push (blocked air flow or circulation?). Once I decided to use the bag (the following weekend) I was much more happy with the ease and power of the machine. Knowing that my yard is the tough and thick Saint Augustine variety, my neighbor - who's family has a landscaping business - thought the battery powered mower would not be able to tackle the job ... I was optimistic, but honestly did not know if it would. The product has a 90 day return policy, so I took a chance and am satisfied. My neighbor, too, is quite amazed as its strength. In addition, with our lots so tightly designed, the quietness of all my Ryobi devices - especially the mower - is astounding. I could cut my lawn at 7:00am and would never be concerned that I was waking my neighbor. I tested this by having my wife advise me whether she could hear me cutting the grass ... her response: "I didn't know you had even started" ... she thought I was "off doing something else" as she did not hear either the mower or the other devices. A welcoming feature in a world that is becoming more and more filled with noise. I can proudly say that I do not disturb my neighbors when I am manicuring my property. Lastly, the mower is light. After use in the hot sun, I can simply pick up the machine by its handle and walk around with it with ease to place it in a tight spot in my garage. I could never attempt to do that with a gas powered mower. Furthermore, with the ease of swapping batteries from one device to the next and then the simplicity and lightness of the entire 40-Volt Ryobi product line, I may now be able to pawn off my lawn duties on my wife (wink). I will end my review stating that after only 2 months of ownership and use, I would recommend the Ryobi 40-Volt battery powered mower (and other devices) for manicuring a lawn nestled in a suburban neighborhood such as mine!
